- Herpes simplex esophagitis has been recognized with increased frequency as an opportunistic infection in immunosuppressed or debilitated patients. However, it is also documented as self-limited esophagitis in apparently healthy patients. We report two cases of herpetic esophagitis diagnosed by biopsies. One case was noted in an immunocompetent patient having gastric peptic ulcer who had clinical improvement with symptomatic treatment. And the other was noted in an immunosuppressed patient having chemotherapy for gastric carcinoma who had resolution of symptoms with acyclovir therapy. Histologically, esophageal mucosa exhibited erosion and inflammatory cellular exudate with intranuclear eosinophilic inclusions in the epithelial cells. These were confirmed by the PCR and immunohistochemical stain for herpes simplex virus using a biopsy material.

Abstract
PDF
- Lymphangioleiomyomatosis(LAM) is a rare disease of women of child-bearing age in which there is progressive hyperplasia of atypical smooth mucle along lymphatics in the lung, and/or axial lymphatics in the thorax and abdomen, resulting in honeycombing of lung. Interestingly there has been a speculation that it represents a forme furste or incomplete expression of tuberous sclerosis complex. This is based on the observation that patients with tuberous sclerosis can manifest pulmonary lesions indistinguishable from LAM. We report a case of LAM occuring in a 39-year-old female, who complained of recurrent pneumothorax, chest pain and shortness of breath. Three years ago, the patient had right nephrectomy under the diagnosis of ruptured angiomyolipoma.
A X-ray film of the chest showed honeycombing with a diffusely reticulonodular pattern and cyst-like spaces. She had a characteristic facial appearance of adenoma sebaceum, which her father and uncle had. Microscopically, the lung showed a marked smooth muscle proliferation around the slit-like lymphatic spaces and also some respiratory bronchioles.

Abstract

- Embryonal carcinoma of testis may be composed of primitive cells with epithelial appearance showing prominent variation in size and shape, clear cytoplasm, overlapping nuclei. and many mitoses. Multiple lymph node enlargement was noticed in a 45-year-old man with known huge testicular tumor, 20 x 15 cm, and clinically malignant lymphoma was suspected.
Microscopic and cytologic finding of both biopsy and needle aspiration from neck lymph node disclosed highly undifferentiated large cells, mostly in solid sheets and often forming glandular spaces. Massive necrosis was observed. Cytologic diagnosis of embryonal carcinoma was made possible, relied on the result of immunohistochemistry that revealed negative LCA, and positive cytokeratin and CEA as well as the cytologic features. Serum levels of HCG and AFP of the patient, in addition, were markedly elevated.

Abstract
PDF
- A case of extrastkeletal Ewing's sarcoma on lower extremity in a 60-year-old male is reported. Extraskeletal Ewing's sarcoma is a rare malignant neoplasm that shows similar histologic and ultrastructural features to Ewing's sarcoma of bone. Histologically, the neoplasm was composed of small, round to oval cells with scant cytoplasm that were arranged in sheets with large area of necrosis. Electron microscopy of the neoplastic cells revaled scant cytopasm containing glycogen rosettes and a paucity of organelles. There is no ultrastructural evidence to indicate the origin of the cells.
