A 1-year-8-month-old boy was admitted to our service on September 30, 1986, complaining of nausea, vomiting and consciousness disturbance lasted for about 2 weeks. In CTs, right frontal cystic mass which was homogeneously enhanced by contrast media was revealed. Neither hypervascularity nor tumor staining were seen angiographically. On October 9, 1986, total removal of the tumor was performed. The tumor was located extracerebrally in the right anterior cranial fossa, but was covered with arachnoid membrane. The tumor showed tight adhesion with falx cerebri, particularly at crista galli where an invasive infiltration was seen. Light microscopic examination demonstrated oval or spherical small cells arranged multilobularly with rosette like formation and numerous mitoses. Ultrastructurally, cilia, microvilli and junctional complexes were observed. No dense-cored secretory granules were found in the tumor cells. Immunohistochemical study on this tumor showed negative NF and GFAP; positive NSE, S-100, vimentin and keratin. From these findings, the tumor was diagnosed as esthesioneuroepithelioma. Postoperatively, irradiation and chemotherapies were also performed, and the patient showed uneventful course. On January 31, 1987, he was discharged on his foot, and no recurrent or metastatic signs could be found until the end of March of 1990.

Here we report an unusual case of T-cell lymphoma presenting as ascites. A 49-yr-old woman was admitted to the hospital for abdominal discomfort associated with increasing abdominal girth over the course of 3 mo. She also complained of nausea, vomiting, and diarrhea. On physical examination, a tense and distended abdomen and edema of the lower extremities were noted. Neither hepatosplenomegaly nor lymphadenopathy was found. A CT scan of the abdomen and pelvis showed a large abdominal/pelvic mass surrounding the small bowel and omentum and small nodes in the para-aortic and mesenteric regions. The cytospin prepared from the peritoneal fluid was hypercellular and composed of a population of monotonous, noncohesive cells with a high nuclear/cytoplasmic ratio and a single prominent central nucleolus. The cells were positive for leukocyte common antigen and Leu-22 (CD43) but negative for keratin, L26, UCHL-1, kappa, lambda, CD3, Ki-1 (CD30), S-100, and carcinoembryonic antigen. Morphologic and immunologic findings were suggestive of T-cell immunoblastic lymphoma. Peripheral T-cell lymphomas rarely present as ascites; this case demonstrates the value of effusion cytology in making this diagnosis.

An anterior mediastinal cystic lesion in an 11-year-old mongrel dog was examined. The dog showed dysbasia and vomiting due to megaoesophagus, and anterior mediastinal round mass lesion, approximately 35 mm in diameter, was found by X ray. Based on clinical examinations, the dog was diagnosed as acquired myasthenia gravis and was successfully controlled by anticholinesterase treatment for approximately 4 months. The dog died of thermic stroke and was necropsied. Grossly, fatty tissues with cysts containing yellowish fluid and white nodules were found in the anterior mediastinal area. Histopathologically, multiple cysts, neoplastic tissues, and atrophic thymus were found within the examined tissues. The cysts were lined by thin wall consisting of ciliated long cuboidal and non-ciliated round cells and were filled with eosinophilic colloidal fluid. Some extended cysts contained neoplastic foci within their lumen and walls. The neoplastic tissues consisted of mixed population of large epithelial cells with abundant clear cytoplasm and large oval nuclei, and lymphocytes. Immunohistochemically, proliferating epithelial cells were intensely positive for keratin and cytokeratin, and more than half number of infiltrating lymphocytes were intensely positive for CD3 suggesting T cells. All these findings indicate the neoplastic lesion is thymoma and multiple cysts are considered as thymic or brachial cleft cysts.
