Colophony allergy from paper has been implicated in hand dermatitis schedule 6 medications eldepryl 5 mg buy, and the use of cotton gloves is suggested if this is a possibility [21]. However, the list of potential exposures is so extensive that it will often be a case of establishing whether any of the sources identified in Box 128. It was used as an industrial solvent but has now largely been replaced by petroleum derivatives and dlimonene. In certain producing countries such as Spain and Portugal, turpentine is still more widely used than elsewhere, and it remains a common allergen there. The threshold of reaction varies in each individual case and depends on the dose given and the level of sensitivity. Reactions may occur not only after systemic exposure to the primary allergen but also to closely related allergens. The most frequent types of reaction are focal flares of previous patch tests and sites of previous dermatitis, vesicular hand eczema, or more widespread eczema and erythema, sometimes with additional urticarial features. In severe cases vasculitis [1], erythema multiforme [2] and systemic upset may occur. Probably all contact allergens can cause systemic reactions, provided the patient has a sufficient degree of preexisting sensitivity and the dose administered is sufficiently large. The causes are many, and include medicaments that may have been given not only by mouth but also parenterally, rectally, intravesically or as an inhalant. Systemic contact dermatitis from medicaments [6] has decreased as a result of reduced use of topical sensitizers such as the antibiotics streptomycin, sulphonamides and penicillin, and topical antihistamines such as promethazine. Nevertheless, exposure to other topical and systemic medicament sensitizers continues to give problems. However, nickel release from stainless steels, apart from those containing sulphur, is very low [19]. Vitallium, a cast cobalt/ chromium alloy, and titanium may also be used for implants. There are two potential concerns in relation to metal allergy and these implants: namely allergic skin disorders and loosening. There is little doubt that static implants Erythema multiformelike reactions the characteristic presentation is that of a spreading eruption from the primary site, which may also involve distant sites. The rash has features of erythema multiforme, in that single lesions appear targetlike, but the distribution is not necessarily acral as in classic erythema multiforme nor is the histology characteristic.

Anaphylaxis and anaphylac toid reactions are often associated with skin or mucosal changes: in less severe cases symptoms ibs purchase eldepryl 5 mg with mastercard, there may be premonitory dizziness or faint ness, skin tingling and reddening of the bulbar conjunctiva, fol lowed by urticaria, angiooedema, bronchospasm, abdominal pain and vasomotor collapse. Intravenous administration is associated with more severe reactions and rapid progression, over minutes, to cardiac arrest. In cases of insect stingrelated and foodinduced anaphylaxis, the syndrome evolves more slowly [45]. Epidemiology Urticaria is the second most common type of adverse cutaneous drug eruption [46,47]. It has been estimated that 1 in 1500 of the population of Eng land has experienced anaphylaxis at some point in their lives [48]. The incidence of anaphylaxis during general anaesthesia has been estimated to arise in 1: 4000 to 1: 25000 cases [43]. Differential diagnosis Druginduced urticaria needs to be distinguished from other causes of urticaria, especially infection. Druginduced anaphylaxis needs to be distinguished from other causes of anaphylaxis. However, it is critical that causation is addressed and investigated as necessary to prevent accidental recurrence. Pathophysiology the mechanisms underlying druginduced vasodilation, oedema and itch in urticaria are identical to those seen in angiooedema (deeper in skin) and anaphylaxis (systemic circulation). On exposure to the drug, crosslinking of IgE on the surface of mast cells (and possibly basophils) is followed by inflamma tory mediator release (including histamine), which induces vaso dilation, neuronal activation and smooth muscle contraction (see Chapter 8). Cyclooxygenase inhibitors, such as aspirin and indo metacin, may also cause urticaria or angiooedema by pharmaco logical mechanisms. Other drugs, such as radiocontrast media, local anaesthetics and dextrans (in plasma expanders) may release mast cell mediators directly. Deaths from druginduced anaphylaxis are uncommon (<2%); the major predisposing risk factor for poor outcome is coexistent severe asthma [53,54]. Investigations the investigation of immediate drug allergy reactions (charac terized by urticaria, angiooedema or anaphylaxis) is well estab lished and various guidelines represent consensus approaches to the investigation of the culprit drug [55]. The general approach is based upon a careful documentation of the exposure history in the hours preceding the reaction to establish the most likely causa tive drug. Testing involves an escalation of exposures which is stopped if any positive result is identified, thereby minimizing risk. In many circumstances, it is more useful to prove a negative through testing than confirm a drug allergy through testing, so as to establish what is safe for the patient to take. The testing process involves plasma sampling for drugspecific IgE, skin prick testing, intradermal testing and challenge testing. Betalactam allergy reactions are due to IgE recognition of the drug bound to a carrier molecule. Although penicil lin avoidance is not difficult for the majority of cases, adverse outcomes of mislabelling with penicillin allergy are increasingly recognized and confirmatory testing is recommended in specific groups [56].

The common epidermoid cyst is the result of squamous metaplasia in a damaged sebaceous gland symptoms parkinsons disease cheap eldepryl 5 mg amex. Multiple cysts can therefore be seen in patients with more severe lesions of acne vulgaris. Some may result from deep implantation of a fragment of epidermis by a blunt penetrating injury (inclusion cysts). As they are situated in the dermis they raise the epidermis to produce yellowish, white or skincoloured, firm, spherical, smooth, elastic, domeshaped protuberances that are mobile over the deeper structures. They are tethered to the epider mis, and may have a central keratinfilled punctum. The size var ies from a few millimetres to more than 5 cm in diameter and the lesions may be solitary but are commonly multiple. Traumatic inclusion cysts usually occur on the palmar or plantar surfaces, buttock or knee. Investigations Diagnosis is usually clinical and can be confirmed on excision biopsy. Inflamed acne cysts may respond to intral esional triamcinolone, thus obviating the need for excision. On rare occasions, metastatic cancers to the subcutaneous or dermal compartments may simulate a cyst. Complications and comorbidities Suppuration may occur which may lead to an offensive smelling discharge. Cysts that follow acne and have been subject to recurrent inflammation may be difficult to remove completely. They are usually situated on the scalp, and their wall resembles external hair root sheath; hence the name. Inflamed cysts may become tender and the cyst wall can rupture following an infection. The cyst wall may fuse with the epidermis to form a crypt (marsupialized cyst), which can occasionally ter minate by discharging its contents and healing spontaneously. In contrast, the contents may protrude above the surface to form a soft cutaneous horn. Clinical variants Proliferating trichilemmal tumours are uncommon solitary, mul tilobular, large, exophytic masses with a predilection for the scalp in elderly females. Pathophysiology Pathology Trichilemmal cysts are lined by stratified squamous epithelium.

Serum proteins are often abnormal medications causing thrombocytopenia discount eldepryl 5 mg with amex, with a low serum albumin and polyclonal gammopathy. Chest computed tomography or head imaging should be considered depending on clinical symptomatology. Management Treatment is only necessary when a vital organ is being compromised or nodal enlargement leads to significant problems such as airway obstruction [11]. For intracranial duralbased lesions, surgical excision alone is successful in most cases [2]. There is currently no consensus on guidelines for systemic treatment when indicated. Surgical debulking of resectable lesions achieved complete remission in eight of nine patients [11]. Systemic corticosteroids are useful in decreasing size and symptoms, but regrowth often occurs within a short period of discontinuation. Complete remissions achieved with interferon plus chemotherapy [12,13], thalidomide or aciclovir have been reported in case reports [14]. Retreatment and prolongation of therapy, similar to cases of follicular lymphoma, may be indicated in these refractory patients, but this approach is obviously experimental. The cells usually arise from sinusoidal histiocytes, although very rare cases of malignant histiocytosis of Langerhans cell phenotype have been reported. Epidemiology Sex Malignant histiocytosis is a rare disease with a male to female ratio of 3. The disease tends to occur earlier in women (second to third decades) than in men (third to fourth decades) [4]. Ethnicity Reports have suggested an increased incidence of this disease in parts of tropical Africa, with reports from Malawi and Uganda [5,6]. These diseases are separated into monocytic leukaemia, malignant histiocytosis, true histiocytic lymphoma and histiocytic sarcoma based on clinical criteria, but there is an enormous overlap and it may not always be possible to differentiate them. In monocytic leukaemia, the malignancy primarily affects the bone marrow and blood but extramedullary involvement is common. This is classified as part of the myelomonocytic leukaemias and will be covered Chapter 140 on leukaemia cutis. In malignant histiocytosis, the histiocytes retain their ability to migrate through the body, which results in widespread involvement of the reticuloendothelial system. In true histiocytic lymphoma, the cells are derived from fixed tissue histiocytes and the tumours are localized, although they may disseminate. In histiocytic sarcoma, it involves mature histiocytes and represents a highly aggressive disease. Pathology the histological picture in the skin and lymph nodes is similar and the diagnosis can be established in either site. Characteristically, there is an infiltrate of histiocytic cells showing varying degrees of atypia that are typically noncohesive. Cells are large (up to 50 m in diameter) with abundant cytoplasm and distinct cytoplasmic membranes.

A small number of patients may experience a protracted course of cutaneous involvement treatment for plantar fasciitis order 5 mg eldepryl with visa, characterized by a chronic exfoliative dermatitis. Prognostication has been attempted by several researchers in the domains of morphological features, drug characteristics and laboratory results. There is conflicting evidence as to whether or not higher viral titres are associated with a more severe course of disease [22,30]. A number of haematological markers such as eosinophilia, pancytopenia and thrombocytopenia have been proposed to be poor prognostic indicators. A further study linked lymphocytosis, eosinophilia, elevated ferritin and elevated creatinine with greater disease duration, and higher mortality rates [5]. A number of organspecific chronic sequelae may arise following involvement of these organs in the acute phase. In addition, a number of autoimmune phenomena such as alopecia areata and autoimmune thyroid disease are described. In some cases where polypharmacy has been in place, this may not be straightforward, but all efforts must be made to ascribe causality to a likely culprit, based on latency and notoriety data. In all cases, supportive care should be prioritized, placing the patient in a clinical area equipped to provide an intensity of clinical care and monitoring appropriate to the severity of disease. This may involve intravenous fluids, thermoregulation, catheterization to facilitate fluid balance management and supplemental oxygen. However, the majority of patients will require systemic corticosteroid therapy, either via the oral route or the intravenous route, as guided by clinical state. A dose oral prednisolone of 1 mg/kg/day is recommended as initial treatment, with a taperingoff period varying from 1 to 3 months [32]. Where intravenous therapy is required, or where institution of oral therapy has failed to produce a satisfactory clinical improvement, methylprednisolone is indicated [26]. One study using 1 g/day methylprednisolone for 3 days demonstrated safety and improved clinical outcome with this dose [85]. Ciclosporin has been used in this capacity, and is useful in patients where a protracted course of illness. Alternative immunosuppressants such as cyclophosphamide [96], may be used for their steroidsparing effect. Valganciclovir has been used, in theory to combat virus reactivation described in this syndrome [97]. In cases of severe liver involvement, Nacetylcysteine has been used as an adjunct to other treatments [97]. Careful surveillance for coexisting infection, either in an organ or arising in the skin, should be undertaken. However, in the absence of indicators of infection, no empiric antibiotic therapy should be given.

They are typically between 1 and 3 cm in diameter and asymptomatic treatment 10 eldepryl 5 mg purchase overnight delivery, although they may interfere with function. Disease course and prognosis In the largest series of cases reported so far it has been shown that local recurrence occurs in 9% of cases, metastases in 9% and mortality in 2% [6]. It seems that areas with higher grade morphology do not confer a more aggressive behaviour. Metastatic spread may occur many years after the original diagnosis and therefore longterm followup is indicated. Disease course and prognosis the rate of local recurrence varies from 5 to 15% [3,5]. The diffuse variant of this tumour that involves joints is not discussed further in this chapter. Definition and nomenclature Fibrous histiocytoma is a benign dermal and often superficial subcutaneous proliferation of oval cells resembling histiocytes, and spindleshaped cells resembling fibroblasts and myofibroblasts. Their line of differentiation remains uncertain, but these lesions are descriptively classified as fibrohistiocytic tumours because of the microscopic appearance of the tumour cells. Ordinary fibrous histiocytoma is probably the most common cutaneous softtissue tumour. Important clinicopathological variants (cellular, atypical and aneurysmal) are much more uncommon. Note the increased cellularity, fascicular appearance and focal extension into the subcutis. The latter displays different patterns including changes mimicking a squamous papilloma, a seborrhoeic keratosis and lichen simplex chronicus. Occasionally, the epidermal proliferation is associated with immature follicular structures, which are often confused with a basal cell carcinoma. In the dermis, there is a localized proliferation of histiocytelike cells and fibroblastlike cells, associated with variable numbers of mononuclear inflammatory cells. Foamy macrophages, siderophages and multinucleated giant cells are also variably present. Collagen bundles at the periphery of the lesion are surrounded by scattered tumour cells and appear somewhat hyalinized. Focal myofibroblastic differentiation is often suggested, particularly in the cellular variant.

Pathology the central component of the naevus is that of a junctional or compound type treatment for bronchitis cheap eldepryl line, while the periphery of the lesion is composed of junctional nests and may present increased pigment in the dermis [162]. The peripheral halo demonstrates extensive haemorrhage with haemosiderin and fibrin deposits combined with slitshaped vascular channels that dissect in between collagen bundles. Differential diagnosis the differential diagnosis includes targetoid haemosiderotic haemangioma, cockade naevus, traumatized angiokeratoma and melanoma. Jetblack areas with irregular shape and size as well as commashaped vessels are also seen. The periphery of the lesion representing the ecchymotic halo shows an illdefined, pale area surrounded by a reddish zone with jagged edges. Management Part 12: NeoPlasia Management includes reassurance of the patient and the use of a topical antibiotic or steroid preparation until the inflammatory/ haemorrhagic changes have resolved. Currently the entity of Spitz naevi remains a subject of controversy due to their clinical and histological variability, their overlapping histological characteristics with Spitz naevus 132. Refinement of the various clinical and histological subtypes of Spitz naevi has resulted in a highly complex morphological classification of these tumours [171,172]. Epidemiology Incidence and prevalence Spitz naevi account for 1% of excised naevi in children [176]. Approximately 50% of lesions occur in patients under the age of 14 years, 25% between the ages of 15 and 30, and 25% over the age of 30 [177]. Ethnicity Spitz naevi occur predominantly in white populations, but they have also been described in black, Hispanic and Asian groups [181,182]. Pathophysiology Most lesions are acquired, but up to 7% of Spitz naevi can occur congenitally [185]. Naevomelanocytic nests are neatly located between keratinocytes, unlike their disorderly arrangement in melanoma. The naevus cells may be either spindle shaped, streaming into the dermis in interlacing bundles, or epithelioid, arranged in clusters, with giant and multinucleated naevus cells seen among them. The dermal component has prominent cellular pleomorphism and evidence of maturation in the deeper portion of the lesion. Eosinophilic, partially coalescent, Kamino bodies are present in the junctional area and upper papillary dermis. Their presence is neither sensitive nor specific for Spitz naevi as they may also be present in early melanoma. Dermal vessels are dilated and the stroma is oedematous and infiltrated by lymphocytes [180]. Several histological features have been considered to indicate a more aggressive behaviour. A Spitz naevus thicker than 1 mm in depth, with asymmetry, poor circumscription, deeper extension and ulceration is considered to have increased metastatic potential [189].

Varek, 24 years: Pathophysiology Clinical features Mostly solitary, they take the form of a nodule or plaque, flesh coloured or with a bluish colour and angiomatous appearance. A patient can also present with the signs of metal toxicity occurring as a consequence of deliberate poisoning. Two types of cells are easily recognized: small round blue cells with scanty cytoplasm in a fibrillary matrix, and large epithelioid cells with pink cytoplasm and vesicular nuclei. Management Treatment ladder First line · Topical azoles if nonhairbearing skin Clinical variants Giant molluscum lesions may occur and these can be mistaken for large genital warts.

Fabio, 49 years: These include acids, where the stinging may be a pro drome to the development of more severe cutaneous damage. Management the modern treatment approach utilizes a risk stratification strategy based on the extent and severity of disease, which represent the main determinants of outcome. Substance use, health and social problems of service users at 54 drug treatment agencies: intake data from the National Treatment Outcome Research Study. Cholesterol clefts are common in the keratinous material which on immunohisto chemistry is positive for keratin K10 and K17.

Vasco, 60 years: Pathophysiology Disease course and prognosis More than 50% of acute fissures heal spontaneously with conservative management [2]. Although most of the cases in which a primary carcinoma is found result from an underlying sweat gland adenocarcinoma, it is necessary to examine the patient for evidence of an adenocarcinoma elsewhere, particularly of the cervix and rectum. The commonest cutaneous stigma of drug use is a line of puncture scars distributed over a vein, or parallel to it. Patch testing, which is actually a bioassay, remains, at present, the only practical scientific procedure for the diagnosis of allergic contact dermatitis.

Jerek, 22 years: Of note, cholestyramine and other bile acid exchange resins may contribute to malabsorption of vitamin K with possible bleeding complications, and should therefore be avoided [8]. Operative management Once the thermally injured patient has been admitted, resuscitated, all wounds assessed and managed appropriately with escharotomy and dressing, the surgeon needs to determine the most efficient course of action in regards to excision of burn and coverage. Clinical features are not distinctive and eyelid lesions may be confused with a chalazion. When the tumour is attached to the epidermis, the diagnosis may be suspected on clinical grounds, especially if there is a history of discharge.

Copper, 39 years: Occasional desmoplastic trichoepitheliomas are combined with a benign melanocytic naevus and even blue naevus [7]. The prevalence of allergy to nickel in under18s attending for patch tests in Denmark has decreased considerably, from 24. A wide age range is seen, with young children prominently represented in many studies. The incidence is about 7/100 000 live births and up to 40% of such infants are premature [1].

Dawson, 35 years: Early lesions demonstrate oedema, haemorrhage and neutrophils within the septae, older lesions are characterized by fibrosis, periseptal granulation tissue, lymphocytes, histiocytes and multinucleated giant cells [146]. A discoid pattern around the lower trunk and thighs from metal studs in clothing is quite frequent, although the involvement of the thighs from metal suspenders has all but disappeared following the advent of tights (pantyhose). Vehicles and other cosmetic and medicament excipients Lanolin [1] Lanolin is a natural product obtained from sheep fleece. It is characterized by asymptomatic, symmetrical papules on the face, trunk and arms, usually sparing the flexures.

Seruk, 65 years: Clinical features History and presentation Tumours present mainly on the hands with a predilection for the fingers. Investigations: histopathology the most complete study of the histopathology of pressure ulcer and its antecedents in humans is given by Witkowski and Parish [20]. Symptomatic relief for perianal symptoms can be achieved with topical agents including lubricants and mild topical steroids. Nevertheless, exposure to other topical and systemic medicament sensitizers continues to give problems.

Bram, 29 years: Areas of cutaneous atrophy or scarring are not infrequent in the intrauterine form, and vesicular lesions may continue to appear within or at the periphery of these areas [4,10]. Examples of this include the lack of pressure offloading devices or expected patient difficulties in adhering to the treatment plan. Giant melanotrichoblastoma is a variant, which, demonstrates pigmented colonization by dendritic melanocytes [4]. Clinical features Presentation Mycosis fungoides is characterized by polymorphic patches and plaques usually involving limb/girdle sites, the breast and especially the buttock area.

Sven, 37 years: In order to reduce the risk of relapse, the ingredients of all topical medicaments should be established. The vaginal lesions are velvety red erosions or bright red, glazed erythema, which is friable and bleeds when touched. If questioned directly about sunbed use (this information is often not volunteered), many patients will describe sunbedinduced episodes. Ethnicity Reports have suggested an increased incidence of this disease in parts of tropical Africa, with reports from Malawi and Uganda [5,6].

Armon, 26 years: When the tumour is attached to the epidermis, the diagnosis may be suspected on clinical grounds, especially if there is a history of discharge. Pine trees are the source of two significant allergenic materials, colophony and turpentine. It is likely that it represents a reaction pattern to another inflammatory condition. Histological involvement of the central lymph nodes and other organs is a very poor prognostic sign.

Kaffu, 64 years: Facial dermatitis has occurred from steaming chamomile tea, and hand and arm dermatitis from herbal compresses. Most lesions involve the second or third web of the right hand, forming tender nodules and discharging sinuses [11]. Confirmed varicella should be treated early with aciclovir either orally or intravenously for pneumonia or other complications. Prevention of occupational skin disease through use of chemical protective gloves.

Asam, 30 years: Pancytopenia is seen in some cases, and is a negative predictive factor in terms of outcome [49]. When subjected to stretch it is only slightly extensible [1], deformation occurring by flattening out or redistribution of these depressions [2]. We have only seen it as a sensitizer from topical medicaments, although it may be used in hand cleaners, metalworking fluids and occasionally cosmetics. Rarely, individual plaques may become eroded or ulcerated and painful, which is often associated with secondary bacterial infection and such patients may Part 12: NeoPlasia 140.

Orknarok, 52 years: Other reported skin manifestations of congenital rubella have included cutis marmorata, seborrhoea and hyperpigmentation of the forehead, cheeks and umbilical area [7], and discrete deep dimples over bony prominences, particularly the patellae [8]. The mucolytic Nacetylcysteine used to alleviate dry eyes may sensitize, as may mydriatics, especially phenylephrine, with which false negative patch tests occur. Futility in adults or elderly burn patients is usually determined by the sum of age (years) plus burn size (%) plus presence or absence inhalation injury (±14) being greater or equal to 140­150 [11]. Risk factors include diabetes, intravenous drug use, trauma and haematological malignancy.

Surus, 38 years: The condition is due to haemolytic streptococcal infection and should be easily distinguished from napkin dermatitis, although the two can coexist. Jetblack areas with irregular shape and size as well as commashaped vessels are also seen. Vascular lumina are reduced, probably by both internal thickening and smooth muscle hypertrophy [25,33,34,35]. The ultrastructural and histochemical characteristics of these cells mark them as hair matrix cells maturing towards the cortex or root sheath [3,22,23].

Taklar, 40 years: Epidemiology (a) Incidence and prevalence the incidence was determined to be 26 per 100 000 in a study from Norway [1]. Patients most frequently present with pulmonary symptoms associated with systemic malaise, arthralgias, weight loss and fever. Preventative management Topical Systemic Treatment Topical Systemic Fluocinomide 0. This occurs in up to 25% of patients and causes dyspnoea, haemoptysis, increased bronchial secretion and hypoxaemia [32].

Altus, 48 years: History the lesions are pruritic, and flaccid bullae occur which then rupture and crust over. Early recognition and intervention is crucial as delay in diagnosis increases mortality. Giant cell angioblastoma: three additional occurrences of a distinct pathologic entity. In this report a 30yearold patient presented with leukonychia affecting the proximal half of the nails on the fingers and toes.

Kan, 51 years: However, this inflammatory myopathy responds poorly, if at all, to systemic corticosteroids or other immunosuppressive drugs. Investigations Liver function tests are usually normal, while alkaline phosphatase may be raised (which is normal for pregnancy due to placental production) [6]. Randomised controlled study of early pulsed dye laser treatment of uncomplicated childhood haemangiomas: results of a 1year analysis. Severe cases may require a short course of systemic corticosteroids and antihistamines.

Vatras, 50 years: Beryllium usage in dental material has resulted in beryllium stomatitis and hypersensitivity reactions [5]. Immunofluorescence studies are usually negative or demonstrate nonspecific fibrin deposition at the dermal­epidermal junction. Disease course and prognosis the common belief that malignant blue naevi are more aggressive than other subtypes of melanomas was not confirmed in Malignant blue naevus Definition this descriptive term corresponds to malignant melanomas that arise within a blue naevus or resemble a blue naevus. Other chemicals, however, will cause stinging without any significant cutaneous damage.

Knut, 57 years: Lowgrade fibromyxoid sarcoma and hyalinizing spindle cell tumor with giant rosettes: a clinicopathologic study of 73 cases supporting their identity and assessing the impact of highgrade areas. Postirradiation morphoea is a potential complication after radiotherapy, particularly radiotherapy for breast cancer [10,11]. Patients with established photosensitivity who have a flare of their dermatitis may have reacted to an increase in light levels or reexposure to their primary allergen or a crossreacting allergen by airborne contact. Pathology Halo naevi are usually compound melanocytic naevi, although junctional or dermal naevi are occasionally noted.

Treslott, 55 years: Management Treatment depends on the stage and severity of the disease and aims to control pruritus and to prevent blister formation. Among occupations, foundry workers and bakers and the various tasks that involve carrying heated coals are sometimes relevant. There has, on occasion, been a difficulty with nomenclature such that the term Kimura disease has been applied but this condition is now viewed as distinct from angiolymphoid hyperplasia with eosinophils. Incidence and prevalence [2] Paget disease of the nipple is an uncommon occurrence, considering the frequency of breast cancer [3,4].
