Atypical Myeloma Casts Myeloma Cast (Left) these casts are atypical permatex rust treatment order 250 mg diamox amex, but they do not have the hypereosinophilic appearance of usual light chain casts on H&E. No amyloid was present in other areas of the kidney biopsy, and the patient did not have systemic amyloidosis. Atypical Myeloma Cast With Amyloid Myeloma Cast (Left) the light chain casts in the tubules stain strongly blue with a granular and coarse appearance in the toluidine blue section submitted for electron microscopy. Some casts have substructural organization with a lattice framework (not shown), but the absence of this finding is not unusual. Atypical Myeloma Cast Ultrastructure of Cast (Left) At higher magnification, this tubular cast is composed of numerous randomly arranged fibrils, which can be observed in myeloma cast nephropathy whether or not the casts have amyloid. Casts, Tubulopathy, and Histiocytosis Cryocrystalglobulinemia (Left) An unusual case with 3 diagnoses related to a lambda paraprotein shows light chain cast nephropathy, light chain proximal tubulopathy, and crystal-storing histiocytosis. By immunofluorescence, these structures stained for kappa but not lambda light chain. Escape into the cytoplasm may be due to lysosomal rupture, which would be expected to injure the cell. Intracytoplasmic Crystals Intracytoplasmic Crystals (Left) Intracytoplasmic crystals are seen on a silver stain. Lack of high-magnification electron micrographs of tubules may result in the diagnosis of light chain proximal tubulopathy being overlooked. Note the absence of finely granular deposits along the basement membrane, which if present would indicate concurrent light chain deposition disease. The difference in localization of the monoclonal protein is probably related to its physiochemical properties. In this field, the tubular epithelium shows reactive nuclei and cytoplasmic thinning. Mottled Lysosomes Positive Lambda in Tubular Cytoplasm (Left) Light chain proximal tubulopathy without organized inclusions is shown. Basnayake K et al: the biology of immunoglobulin free light chains and kidney injury. Proximal tubules have scattered cytoplasmic inclusions that stain blue on Masson trichrome stain. This patient did not have amyloidosis deposition outside of the proximal tubule cytoplasm. Positive Congo Red Staining Congo Red Staining Under Red Fluorescence (Left) Amyloid proximal tubulopathy is shown. Congo red-positive cytoplasmic inclusions are easily appreciated under red fluorescence. Fibrillary Aggregates in Tubular Cytoplasm Inclusions Positive for Lambda (Left) Amyloid proximal tubulopathy is shown. Cytoplasmic inclusions stain positive for lambda by direct immunofluorescence on fresh tissue. Eosinophilic Inclusions in Silver Stain Kappa Restriction in Proximal Tubules (Left) Light chain proximal tubulopathy with fibrillary aggregates is shown.

On low power ombrello glass treatment diamox 250mg, there is a vaguely nodular appearance, but this is likely caused by the tissue infiltration rather than true nodularity. The neoplastic cells are in the interfollicular area with rare residual follicles. This is a case of myeloid sarcoma, a malignant neoplasm composed of myeloid cells. Conventional cytogenetic analysis of a case of Burkitt lymphoma reveals a karyotype showing the most common translocation, the t(8;14)(q24;q32). Epub ahead of print, 2014 Greenough A et al: New clues to the molecular pathogenesis of Burkitt lymphoma revealed through nextgeneration sequencing. A dominant monoclonal peak was observed, indicative of the monoclonality of Burkitt lymphoma. A normal nucleus produces 2 yellow signals; the red and green signals remain together. The lymphoma cells have round nuclear contours, multiple nucleoli, and basophilic cytoplasm. Typically, Burkitt lymphoma cases have a very high proliferation rate (Ki-67 index > 95%), whereas cases of diffuse large B-cell lymphoma will not typically exceed 80%. This is lambda in situ hybridization staining showing scattered lambda-positive plasma cells. This is a corresponding image from a kappa in situ hybridization with only rare positive cells. In situ hybridization staining often shows less background staining than immunohistochemical staining. The associated serum immunofixation has discrete bands in G and, identifying the M component as IgG lambda. This is the bone marrow aspirate showing sheets of plasma cells, which were clonal by immunohistochemistry. A clonal plasma cell population is necessary for the diagnosis of plasma cell myeloma. Biopsies of bone near lytic lesions show prominent osteoclastic activity adjacent to the trabeculae. Knowing the pattern of aberrant antigen expression is helpful for monitoring residual disease after therapy. The aspirate shows numerous plasma cells, which were clonal on immunohistochemical stains. The main differential in this case is lymphoplasmacytic lymphoma/Waldenstr m macroglobulinemia. The primary differential in this case is lymphoplasmacytic lymphoma/Waldenstr m macroglobulinemia. The cells are intermediate in size, but larger than a normal small mature lymphocyte. There are residual germinal, sometimes making centers differentiation from a reactive process difficult.

Rare Plexiform Perineurioma Intraneural Perineurioma (Left) Rare cases of plexiform perineurioma have been reported medicine 101 order 250mg diamox overnight delivery. This case arose on the lower lip of a 60-year-old woman, and shows the unique multinodular and serpentine growth pattern. Their incidence is likely underestimated given their morphologic overlap with pure nerve sheath tumors. It often resembles perineurioma architecturally yet contains an admixed Schwann cell component. Hybrid Nerve Sheath Tumor S100 Protein Expression (Left) S100 protein expression is common in hybrid tumors due to the presence of Schwann cells, as in this example of hybrid perineurioma/schwannoma. Expression is often greater than that of perineurial markers; however, in some cases it is less abundant. Kacerovska D et al: Hybrid peripheral nerve sheath tumors, including a malignant variant in type 1 neurofibromatosis. Hybrid schwannoma/perineurioma often contains areas of prominent collagenization, as shown. Myxocollagenous Stroma Myxocollagenous Stroma (Left) Some cases of hybrid nerve sheath tumor are extensively myxoid and may histologically and clinically mimic a myxoma. There is minimal to no cytologic atypia, and there are no mitotic figures or necrosis. Diffuse Myxoid Stroma Neurofibroma-Like Areas (Left) Areas of hybrid nerve sheath tumor may resemble neurofibroma, particularly when small, separated collagen fibers are present, as depicted in this image. Perineurioma-Like Areas 530 Hybrid Nerve Sheath Tumor Peripheral Nerve Sheath Tumors Corded S100 Expression Pattern Minor S100 Protein Expression (Left) A cord-like pattern of S100 protein expression may be seen in hybrid perineurioma/schwannoma, due to alternating rows and thin layers of Schwann cells and perineurial cells. Rare Fat Infiltration Rare Hyalinized Vessels (Left) Most cases of hybrid nerve sheath tumor are well circumscribed; however, occasional cases show limited infiltration and entrapment of mature adipose tissue, as depicted. Degenerative Atypia Hybrid Schwannoma/Neurofibroma (Left) Degenerative nuclear atypia ("ancient change") may be seen in some cases of hybrid nerve sheath tumor similar to pure nerve sheath tumors. Of note, some cases of these particular tumors may be associated with neurofibromatosis or schwannomatosis. Most cases are dermal or subcutaneous, and some may extend directly up under the overlying epidermis. Nuclei are generally small and may be dark with dense chromatin or vesicular with a small nucleolus.

A midline lesion may travel to bilateral inguinal nodes symptoms white tongue generic 250mg diamox, but a lateral lesion will almost always be isolated to the ipsilateral nodes. Lichen sclerosis is a chronic condition characterized by thin, cigarette paper-like, crinkly epithelium. Frequent surveillance of the vulva is necessary as to prevent squamous cell carcinoma of the vulva. Vulva cancer is staged surgically including dissecting the ipsilateral inguinal lymph nodes. Bartholin gland cysts are treated by Word catheter or marsupialization so that drainage for several weeks can occur. The explanations to the answer choices describe the rationale, including which cases are relevant. Surgical therapy and removal of an ovarian tumor A 32-year-old woman is noted to have 1200 cc of blood loss following a spontaneous vaginal delivery and delivery of the placenta. Surgical repair via vaginal route A 32-year-old woman comes into the office not having menstruated for 3 months. H er menarche occurred at age 11, and she had regular menses each month until 3 months ago. If the patient in R3 is prescribed and takes a 28-day package of combination oral contraceptive pills, which of the following is most likely to occur Oral progestin is given for 7 days leading to vaginal bleeding after the progestin therapy. Atrophy noted of the vulvar and vaginal epithelium A 55-year-old woman is noted to have an abdominal mass and increased abdominal girth. On examination, her heart rate (H R) is 120 bpm and respiratory rate is 32 and labored. The chest radiograph reveals bilateral pulmonary infiltrates and also an enlarged cardiac silhouette. On ultrasound, there are two cystic structures noted in the fetal abdomen- one on the left side, and another cystic structure on the right side. The patient is noted to have an ultrasound that reveals no gestational sac and no adnexal masses. W hich of the following statements is most accurate regarding the management for this patient This patient should be offered methotrexate for ectopic pregnancy provided her vital signs are normal.

Approach to Reading the clinical problem-oriented approach to reading is different from the classic "systematic" research of a disease 5 medications that affect heart rate diamox 250mg buy line. Patients rarely present with a clear diagnosis; hence, the student must become skilled in applying the textbook information to the clinical setting. In other words, the student should read with the goal of answering specific questions. Likewise, the student should have a plan for the acquisition and use of the information; the process is similar to having a mental "flowchart" and each step sifting through diagnostic possibilities, therapy, complications, and risk factors. The method of establishing the diagnosis has been covered in the previous section. One way of attacking this problem is to develop standard "approaches" to common clinical situations. It is helpful to understand the most common causes of various presentations such as "the most common cause of postpartum hemorrhage is uterine atony. With no other information to go on, the student would note that this patient has postpartum hemorrhage (blood loss of > 500 mL with a vaginal delivery). Using the "most common cause" information, the student would make an educated guess that the patient has uterine atony. Now the most likely diagnosis is a genital tract laceration, usually involving the cervix. Thus, the first step in patient assessment and management is uterine massage to check if the uterus is boggy. If the uterus is firm, and the woman is still bleeding, then the clinician should consider a genital tract laceration. Now, the student would use the Clinical Pearl: "The most common cause of postpartum hemorrhage with a firm uterus is a genital tract laceration. This question is difficult because the next step has many possibilities; the answer may be to obtain more diagnostic information, stage the illness, or introduce therapy. It is often a more challenging question than "W hat is the most likeyly diagnosis Another possibility is that there is enough information for a probable diagnosis, and the next step is to stage the disease. H ence, from clinical data, a judgment needs to be rendered regarding how far along one is on the road of: Make a diagnosis Stage the disease Treat based on stage Follow response Frequently, the student is taught to "regurgitate" the information that someone has written about a particular disease, but is not skilled at giving the next step. Make a diagnosis: "Based on the information I have, I believe that this patient has a pelvic inflammatory disease because she is not pregnant and has lower abdominal tenderness, cervical motion tenderness, and adnexal tenderness. Stage the disease: "I do not believe that this is a severe disease because she does not have high fever, evidence of sepsis, or peritoneal signs. An ultrasound has already been done showing no abscess (tubo-ovarian abscess would put her in a severe category).

In some cases medicine ball chair generic 250mg diamox visa, the tumor cell nodules are separated by thick fibrous septa, as seen in this image. Together with the cytologic features, this morphology can raise suspicions for melanoma. Extensively myxoid examples can closely resemble soft tissue myoepithelioma or myoepithelial carcinoma. Much less commonly, it may arise out of a benign nerve sheath tumor, particularly a schwannoma. Stellate and multinucleated forms are common and are often seen close to the overlying mucosa. This variant has been described as cellular pseudosarcomatous fibroepithelial stromal polyp. At low magnification, the classic morphologic pattern is that of irregular zones of cellularity within a myxoid or fibrous stroma. Circumscription Alternating Zones of Cellularity (Left) the neoplastic cells of angiomyofibroblastoma are characteristically clustered around small thin-walled capillary channels, which can often be recognized by the presence of intraluminal erythrocytes. Magro G et al: Vulvovaginal angiomyofibroblastomas: morphologic, immunohistochemical, and fluorescence in situ hybridization analysis for deletion of 13q14 region. This pattern may mimic the growth of lobular carcinoma of the breast or a Sertoli cell tumor. Cording Growth Mature Adipose Tissue (Left) A component of mature adipose tissue is seen in a minority (~ 10%) of cases of angiomyofibroblastoma. These tumors have been referred to as "lipomatous angiomyofibroblastoma" when the fat is prominent. Vasculature Vasculature (Left) In rare cases of angiomyofibroblastoma, larger dilated vessels forming an ectatic "staghorn" pattern may be apparent. This finding is generally nonspecific, but it may raise the consideration of a solitary fibrous tumor. Subtle Perivascular Arrangement Desmin Expression (Left) this image of angiomyofibroblastoma in a postmenopausal patient demonstrates a marked drop in overall cellularity but also shows how the tumor cells (more spindled rather than epithelioid) congregate around the capillary channels. Cellular Angiofibroma Deep (Aggressive) Angiomyxoma (Left) In contrast to angiomyofibroblastoma, cellular angiofibroma is more uniformly cellular. The vessels are often of a larger caliber, and usually show at least focal hyalinization. Unlike angiomyofibroblastoma and aggressive angiomyxoma, cellular angiofibroma is well described in men. Cellularity can vary widely from field to field; however, cells are usually evenly distributed regardless of the overall cellularity. Conspicuous Vasculature Hyalinized Vessels (Left) Perivascular hyalinization or fibrosis is seen at least focally in most cases of cellular angiofibroma and may affect both small and larger vessels.

A glycosylated hemoglobin level (H bA1c) < 7% correlates to neonatal morbidity and mortality rates similar to the general population medications 73 diamox 250mg low cost. In contrast, those with HbA1c levels >10%experience rates of congenital anomalies (typically cardiac, skeletal dysplasias, and neural tube defects) as high as 20%to 25% Folate supplementation is extremely. Other important tests include: thyroid and renal function, 24-hour urine for protein, and an ophthalmological examination for retinopathy. It can occur with blood glucose levels as low as 200 mg, and should be suspected with an arterial pH of <7. This type of hormonal imbalance enhances hepatic gluconeogenesis, glycogenolysis, and lipolysis. Decreased serum bicarbonate levels to compensate for the primary respiratory alkalosis, which reduces the buffering capacity. Increased tendency for ketosis with increased lipolysis and free fatty acids and ketones. Precipitating factors include emesis, infection, noncompliance or unrecognized new onset of diabetes, and maternal steroid use. Fluid replacement should begin with 1 to 2 L of isotonic saline during the first hour followed by 300 to 500 mL/ h of normal saline. When glucose levels approach 200 to 250 mg/ dL, the insulin infusion rate may be decreased to 1 to 2 U/ h. Inevitably, the total body potassium is depleted, even though the serum potassium may be normal or even elevated due to the shifting of potassium extracellularly as the excess hydrogen ions move intracellularly. If serum potassium is elevated, potassium replacement should be provided at 20 mEq/ h after urine output is established. If serum potassium is below normal, replacement should be initiated immediately at the above rate. Delivery of the fetus for heart rate abnormalities should not be performed unless the abnormalities are persistent even after maternal stabilization. Selective screening based on risk factors would reduce the number of women requiring screening by 10% to 15%, however, it would fail to identify one-third to one-half of affected individuals. The first step involves a 50-g 1-hour screening test, and the second step utilizes a 100-g 3-hour diagnostic test for those women identified via the initial screening test. The diagnosis of gestational diabetes depends on noting two abnormal values on the 100-g 3-hour test with variations on the cutoffs.

There is marked mesangial matrix expansion but no appreciable mesangial hypercellularity medications used to treat adhd buy diamox 250mg free shipping. The glomerular capillary loops and mesangial matrix contain numerous subendothelial and intramembranous lipid of differing density, size, and shape. This produces the thickened foamy appearance of the capillary loops on silver stains by light microscopy. Ultrastructural aspects of a new syndrome with particular reference to lesions in the kidneys and the spleen. There is mild mesangial matrix expansion and a mild increase in mesangial hypercellularity without obvious vacuolization. There is mild mesangial matrix expansion without obvious vacuolization or hypercellularity. This is due to extraction of the lipid deposits during processing for paraffin embedding. Severe Glomerular Involvement With Vacuolated Mesangial Matrix Severe Mesangial Lipid Deposition (Left) There is prominent mesangial matrix expansion and vacuolization. This results in a vacuolated appearance to the mesangial matrix and capillary loop basement membranes. Although the mesangial and subendothelial lipid deposits, in this case, stain faintly, most often they will not stain. The matrix contains electron dense lamellar material and lucencies resulting from incomplete lipid extraction. The mesangial matrix has a vacuolated appearance with lucent and lamellar material. The rounded deposits are solid or have a lamellar substructure and are unusually electron dense. Fat Stain Shows Lipid in Glomeruli Lipid "Thrombi" (Left) In lipoprotein glomerulopathy, glomerular capillaries are filled with vacuolated lipoprotein thrombi. Goto S et al: Marked elevation of serum hyaluronan levels in collagenofibrotic glomerulopathy. Alchi B et al: Collagenofibrotic glomerulopathy: clinicopathologic overview of a rare glomerular disease. The tannic acid highlights the randomly arranged, curved, and banded collagen fibers within the mesangium. The interstitium also stains, but this is a normal feature of interstitial fibrosis. The capillary loop basement membrane shows marked thickening and irregularity with basement membrane lucencies that contain tiny cell remnants. There is a small segmental sclerosing lesion with hyaline accumulation and tiny lipid droplets. There is diffuse podocyte foot process effacement with microvillus transformation. The glomerulus on the left shows mild mesangial matrix increase with mild mesangial hypercellularity.

Normal splenic tissue is present surrounding the lesion treatment 5th metatarsal base fracture purchase generic diamox pills, and a normal capsule overlies the spleen. Neoplasm shows increased cellularity with mildly atypical endothelial cells associated with poorly formed vascular spaces with features intermediate between angiosarcoma and hemangioma. Yu L et al: Kaposiform hemangioendothelioma of the spleen in an adult: an initial case report. Kumar M et al: Hemangiopericytoma of the spleen: unusual presentation as multiple abscess. Goyal A et al: Hemangioendothelioma of liver and spleen: trauma-induced consumptive coagulopathy. The original designation of the tumor for those cases combining endothelial and myoid features was myoid angioendothelioma. High-power image shows vascular lumina and pleomorphic endothelial cells with irregular nuclear shapes. Hamartoma Benign lesion of uncertain etiology Composed of red pulp without white pulp Rarely shows bizarre stromal cells 4. Malignant vascular tumors including both malignant epithelioid hemangioendothelioma & angiosarcoma have proclivity for multifocal involvement of visceral sites. The heterogeneous appearance characteristic of malignant vascular lesions correlate with extensive areas of necrosis, vascularity and solid tumor growth are seen histologically. The finding of a tumor with both solid areas and vascular areas is characteristic of angiosarcoma. The lesions of splenic peliosis preferentially localize to the parafollicular areas. Report of a case associated with chronic myelomonocytic leukemia, presenting with spontaneous splenic rupture. Lymphangiectasia Dilated lymphatic vessels filled with proteinaceous fluid Positive for D240; cases of peliosis will be negative 7. Note the absence of any endothelial lining with only the presence of splenic parenchymal cells along the edge of the space. Diffuse staining of the lining of the cystically dilated spaces is generally not present. Diffuse vascular marker staining of these spaces should warrant consideration of a true vascular neoplasm. At this power, the lung may look within normal limits, and in a cursory review, the pathological process can be easily missed.

Jens, 35 years: The activation of complement by the IgG:antigen complexes generates the complement component C3a, a potent stimulator of histamine release from mast cells, and C5a, one of the most active chemokines produced by the body. These are seen in human, nonhuman primate, pig, and mouse renal allografts (shown) after tolerance induction by a variety of protocols. Selye H et al: Pathogenesis of the cardiovascular and renal changes which usually accompany malignant hypertension. The brown staining highlights the preserved basal cells that express cytokeratin 5 and p63.

Daryl, 55 years: The vessels are most prominent in areas populated by the neoplastic small round cells. Separations of the subcutaneous tissue anterior to the fascia are usually associated with infection or hematoma. Myoglobin Cast Diabetic Glomerulosclerosis (Permanent Section) (Left) the donor of this kidney died from trauma and the kidney had severe tubular injury, with granular eosinophilic casts that stained for myoglobin. A large cardiac silhouette may indicate peripartum cardiomyopathy, which is treated by diuretic and inotropic therapy; pulmonary infiltrates may indicate pneumonia or pulmonary edema.

Vatras, 49 years: Wang G et al: Gastrointestinal tract metastasis from tubulolobular carcinoma of the breast: a case report and review of the literature. With genuine stress urinary incontinence, the proximal urethra has fallen outside the abdominal cavity (B) so that the intra-abdominal pressure no longer is transferred to the proximal urethra, leading to incontinence. Use of cell lines as batch controls helps ensure proper assay performance, sensitivity, and dynamic range for each staining run. Laboratory tests revealed profound anemia (Hb: 3 g dl­1) and thrombocytopenia (platelet count: 8 x 109 l­1).

Abe, 65 years: Note the maintained lobular architecture, with fibrous septa creating the separation. Podocytes are densely arranged, forming a corona at the periphery of the capillary loops. The size of the ovary is enlarged with a dominant follicle related to stimulation from residual maternal gonadotrophins. Since pregnancy and delivery is a normal physiological process, the purpose of the prenatal care is to educate and build rapport with the patient and family, establish gestational age, screen for possible conditions that may impact maternal or fetal health, and monitor the progress of the pregnancy.

Felipe, 37 years: Myxoid Stromal Change Stromal Hyalinization (Left) Stromal hyalinization and hypocellularity is another common finding in leiomyoma and may be focal or diffuse. This case shows the characteristic collapsing glomerular lesion that is seen in this disease. Fibrin thrombi identified in several arterioles likely precipitated cortical necrosis. The patient died shortly after the diagnosis of intravascular large B-cell lymphoma was established.

Agenak, 58 years: Migraines with aura increase the risk of strokes in patient who take combination hormonal contraception. There is diffuse interstitial fibrosis & tubular atrophy with persistent inflammation. However, due to the dyscohesive nature of the cells, edge enhancement can be seen. Nail-patella syndrome, 259, 436­437 - diagnostic checklist, 437 - differential diagnosis, 437 - Galloway-Mowat syndrome vs.

Kan, 62 years: An abnormal eccrine unit wraps around abnormal capillaries that are variably ectatic, with red cell extravasation and features of traumatization. The lesions have ragged edges, a necrotic base, and there is adenopathy noted on the right inguinal region. Hence, a palpable breast mass in the face of a normal mammogram still requires a biopsy. She has no rashes on her body and is diagnosed as having probable intrahepatic cholestasis of pregnancy.

Grim, 47 years: Know that an unengaged presenting part, or a transverse fetal lies with rupture of membranes, predisposes to cord prolapse. This pattern is likely due to rapid growth resulting in ischemia in the center of the tumor. Tumor cells may form sheets, short fascicles, loose storiform arrays, or a variety of other unusual patterns. The lesions are often plaque-like, as seen on the soles of the feet with skin breakdown resulting in fungating lesions.

Baldar, 22 years: A hysterosalpingogram visualizes the inside of the uterus and would not be helpful in the diagnosis of endometriosis, since it manifests outside the uterus, tubes, and ovaries. Allograft Hilar Venous Thrombus Hemorrhagic Necrosis From Venous Thrombosis (Left) Necrosis of the cortex with congestion and hemorrhage are seen in a renal allograft removed for renal vein thrombosis on day 5 post transplant. She is asymptomatic until postoperative day 9, when she develops profuse nausea and vomiting, and is noted to have ascites on ultrasound. The normal ducts show strong membrane immunoreactivity and provide a good internal control.

Killian, 40 years: The irregular border is due to infiltration of the tumor cells into the adjacent stroma. The mucosa shows marked inflammation with scattered lymphocytes invading the epithelium. The contours of the endometrium are altered and therefore, less favorable for implantation. It inhibits microtubule-dependent processes in the cell, including the division of neutrophil precursors and the secretion of pro-inflammatory mediators by mature neutrophils.

Asam, 48 years: There is abundant vascular proliferation on both sides of a region of necrosis with pseudopalisading of tumor cells. This must be communicated to the pathologist as no seed was received in the specimen. There is actually no true migration but apparent ascent due to disparate caudal growth of the fetus, leaving the kidney behind. The blue line shows the rate of disappearance of IgG in a normal person and the red line the rate in a male with X-linked agammaglobulinemia.

Hjalte, 34 years: Surgical repair via vaginal route A 32-year-old woman comes into the office not having menstruated for 3 months. Like rapidly dividing cancer cells, lymphocytes mediating autoimmune and inflammatory responses are proliferating rapidly and can be targeted by antimetabolite drugs. Regardless of whether E antigen is present, this baby when born should receive hepatitis B immune globulin to protect against immediate exposure, and then the active hepatitis B vaccine for lifelong immunity. However, clues to the possible diagnosis of a vascular tumor seen here include tumor cell dyscohesion with intermixed red blood cells filling the ragged open spaces, and blister cells (cells with cytoplasmic vacuoles that indent the nucleus and which may represent early vessel formation).
