Papillary cystadenoma of the epididymis is a rare benign tumor that represents the epididymal component of von Hippel-Lindau Syndrome. A case of epididymal papillary cystadenoma is presented in a 36 years old man. He also had pancreatic cysts, the pancreatic component of von Hippel-Lindau syndrome. His younger brother, who died of intracranial hemorrhage at age 27, revealed hemangioblastoma of the cerebellum, angioma of the retina and renal cell carcinoma on radiologic studies. These findings suggest familial occurrence of von Hippel-Lindau syndrome.

Glomeruloid hemangioma is a histologically distinctive cutaneous hemangioma that has recently been associated with POEMS (polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes) syndrome. We report two cases of glomeruloid hemangioma associated with POEMS syndrome. Histopathology of two cases showed multiple dilated vascular spaces composed of a conglomerate of capillaries, resulting in structures resembling renal glomeruli. Periodic acid-Schiff positive and diastase-resistant eosinophilic globules were found within the cytoplasm of vacuolated endothelial cells.

There is a wide array of designation for cutaneous vascular disorders based on clinical characteristics, histology, embryology, cellular biology, and hemodynamics. The cutaneous vascular disorders can be divided into hemangioma and vascular malformation according to the biologic classification based on cell kinetics i.e. endothelial hyperplasia. There are clinical and histologic differences between them. In this study, clinical, histologic and im-munohistochemical evaluations were attempted on 40 cases of cutaneous vascular disorders diagnosed the period between 1985 and 1993. The results are as follows: 1) Twenty-three out of forty cases were immunoreacive for proliferating cell nuclear antigen(PCNA). The lesions composed of capillary-sized blood vessels with endothelial hyperplasia were diffusely reactive, whereas those composed largely of dilated blood vessels with or without focal endothelial hyperplasia were only focally reactive. 2) Each groups of the classic classification contained both reactive and nonreactive cases except nevus flammeus and juvenfle hemangioma. 3) In contrast to the cases nonreactive for PCNA, those reactive for PCNA contained areas of proliferating small vessels, which showed reactivity for PCNA. In conclusion, the cutaneous vascular disorders diagnosed by the classic classification are heterogeneous in the pattern of the endothelial hyperplasia and the PCNA staining. Therefore it should be classified by the clinical and the histologic characteristics.

Schwannoma is a benign encapsulated nerve sheath tumor and is histologically characterized by a mixture of Antoni type A and B tissue. A preoperative diagnosis of schwannoma by fine needle aspiration cytology or by any other means is important to preserve clinically important nerves. Therefore, it is necessary to make a specific cytological diagnosis of nerve sheath tumor. However, there are a few reports regarding cytological features of schwannoma in Korea. We experienced seven cases of solitary schwannoma and here we report their characteristic cytological features with a review of literatures. The characteristic features of schwannoma on cytology were the presence of both Antoni type A and B tissue. The cytologic findings common to all cases of schwannoma generally corresponded to the histologic findings of Antoni type A tissue, consisting of fragments of tightly cohesive fascicles with variable cellularity. Dense fibrillary substances were found, along with palisading nuclei and Verocay bodies. Individual tumor cells consisted of cohesive cells having spindle or oval nuclei, with pointed ends and indistinct cell borders. Variation in nuclear size and shape was also present. The Antoni type B consisted of scattered wavy or short spindle cells and some histiocytes and lymphocytes in the abundant myxoid background with formation of microcysts. Immunohistochemistry for S-100 protein revealed a uniformly strong positive reaction and was helpful to make more accurate diagnosis of schwannoma.

PURPOSE: A study was conducted to evaluate the clinical characteristics of patients with postcoital hematuria without bloody ejaculate. MATERIALS AND METHODS: The records of 21 men(mean age 48.6 years, range 27-64 years) with isolated postcoital hematuria without bloody ejaculate were retrospectively reviewed. Patients underwent routine laboratory testing including coagulation studies and urological evaluation which included urinalysis, urine cytology, abdominal and transrectal ultrasonography, and cystourethroscopy. RESULTS: Among total 21 patients, there were no detectable abnormalities in 11(52.4%) patients. Lesions were found in 10(47.6%) patients, which included 1 pathologically proven prostatic urethral hemangioma, 5 benign prostatic hyperplasia, 1 bladder neck obstruction, and 3 ultrasonographically identified seminal vesicle dilatation. In 19(90.5%) patients, symptom subsided after treatment or simple observation without recurrences. In the remaining two patients, postcoital hematuria has still persisted intermittently. CONCLUSIONS: Thorough evaluations are necessary in the case of postcoital hematuria as treatable lesions could be identified. In cases without identifiable causes, the patients could be reassured that the condition is benign and self-limiting.
