Carcinoma of the male urethra is uncommon and its prognosis is very poor except anterior urethral tumor. Urethral tumors in the male patient comprise lees then 1 per cent of all urologic malignancies. We report here a case of squamous cell carcinoma of the posterior urethra in a 68-year-old man who has been suffered from urethral discharge for several years.

Gastric leiomyomas, which arise from smooth muscle tissue, are the most common non-epi- thelial tumors occurring in the stomach. This tumor is most commonly found incidentally at surgery or autopsy. The incidence of the leiomyoma is about 1-3% of all gastric tumors and sex distribution is equal. We have recently experienced a 59-year-old housewife who had epigastric pain and soreness of one month's duration. Physical examination disclosed tenderness with palpated mass in the left upper quadrant. Gastrofiberscopic finding revealed esophageal diverticulum in the mid-esophagus and 2 x 2 x 1 cm sized submucosal intramural mass with centrally depressed umbilication through ulcerative change on the greater curvature of lower body. Within the umbilication, there were food materials and blood clots. The sleeve segmental resection of stomach was performed. The histopathologic and post operative findings were atypical leiomyoma, perforated with abscess formation to the omentum.

The morphdogical changes in mast cells, induced by horseradish peroxidase (HRP) and distilled water were studied, using light and electron microscopy. The mesenteries of rats sacrificed at 30 minutes; at 1, 2, 4 and 18 hours; and at 1, 2, 3 and 6 weeks after an intraperitoneal injection of 250 microgram or 500 microgram of HRP or 10 ml of distilled water were used for observation of degranulation rates and morphological changes in cell organelles during specified time intervals. The results were as follows: 1) A distinct increase in the mast cell degranulation was observed in the mesenteries after injection of HRP. In particular, all mast cells were disrupted or degranulated significantly 18 hours after injection of distilled water. 2) The degranulating mast cells of the group injected with HRP showed a progressive decrease in electron density of the granules, formation of perigranular cavities, and extrusion of the granules after partial loss of the plasma membrane. 3) At 2 weeks after injection of HRP, some indicators of the early stage of regeneration, that is, peripherally placed nucleus, the expanded Golgi area containing numerous vesicles, and progranules in these vesicles, were observed. 4) After 6 weeks, the morphological characteristics of most mast cells in the group injected with HRP were nearly the same as those of the control group. 5) In degranulating mast cells of the group injected with distilled water, partial rupture of the plasma and cytoplasm with wide dispersion of the granules.
