We herein present two cases of angioleiomyoma with unusual location and number of cutaneous lesion. One was 58-year-old male who has two small peasized nodules on the left palm and volar aspect of the left fifth finger. The other was 63-year-old male with three small pea-sized nodules on the left palm, volar aspect of the left middle finger and the right sole. We confirmed these as angioleiomyoma by clinical and histopathological findings.

Sixty-one cases in which the diagnosis of epithelial cysts had been made studied. The data were collected from our own clinical records and a review of all histopathologic slides of epithelial aysts that had been filed at Departrnent of Dermatology, Chosun University Hospita.l during the past g years from July, 1979 to June, 1984. The results were as follows: 1) Among the 61 cases of epithelial cysts, 41 cases were epidermal cysts, 10 cases of milia, 7 cases of steatocystoma. multiplex, 2 cases of pilar cysts and 1 case of eruptive vellus hair cyst. 2) The average age of these patients was third decade. 3) The commonest site of epidermal cyst and milium was face. Two cases of pilar cyst occurred only on the scalp. Fteatocystoma multiplex was developed on the several sites, but not on the scalp and scrotum, 4) The average diameter was 6. 5 mm for epidermal cyst, p 6 mm for milium, 3 1 mm for steatocystoma multiplex and 17 mm for pilar cyst.

Congenital lymphedema is a rare disorder of unknown etiology which affects the extremities, preponderantly the lower extremities, at or immediately after birth. We experienced a case of congenital lymphedema in a newborn with generalized edema on the left lower extremity. We performed lymphangioscintigraphy and MRI for diagnosis. Microlymphaticovenous anastomosis was done on 16 days after birth and the patient showed clinical improvement. We report this case with brief review of the related literature.

The purpose of this study was to investigate the characteristics or the potassium channels existing in the rat urinary bladders. Smooth muscle strips of rat detrusor urinae were examined by isometric myography. Relaxation responses of detrusor muscle strips to the three potassium channel openers pinacidil, a cyanoguanidine derivative, BRL 38227, a benzopyran derivative and RP 52891, a tertrahydrothiopyran derivative were examined. The potassium channel openers reduced the basal tone, and the rank order of potency was RP 52891>pincidil>BRL 38227. Procaine, an inhibitor of the voltage-sensitive potassium channel tended to increase the basal tone, but it did not affect the relaxant effects of the calcium-activated potassium channel opener did not antagonize the relaxant effects, but it reduced the Emax of RP 52891 and BRL 38227. Glibenclamide, an inhibitor of the ATP-sensitive potassium channel, antagonized the relaxant effects of pinacidil, RP 52891 and BRL 38227 reducing the Emax of RP 52891 and BRl 38227. Galanin which inhibits secretion of insulin through opening the ATP-sensitive potassium channels in pancreatic β-cells rather increased the basal tone of the isolated detrusor strips. These results suggest that the urinary bladder of the rat has mainly the ATP-sensitive, glibenclamide sensitive potassium channel, which is a different type from that in the pancreatic β-islet cells.

Ancient (degenerated) schwannomas are benign tumors that display pronounced degenerative changes including cyst formation, calcification, hemorrhage, and hyaliniz ation. The tumors are usually infiltrated by large numbers of inflammatory cells such as neutrophils, lymphocytes, siderophages, and histiocytes. They are located in deep locations such as the retroperitoneum and must be differentiated from malignant soft tissue tumors because spindle cells with nuclear atypia may be present in the fine needle aspiration biopsy. The cytologic findings of two cases of ancient schwannoma occurring in posterior mediastinum and retroperitoneum, respectively, are described. Computerized tomographic findings of both cases showed changes of cystic degeneration or necrosis. A case occurred in retroperitoneum revealed features of destruction of vertebral body to suggest a malignant soft tussue tumor radiologically. The cytologic findings of aspiration biopsy of both tumors revealed that the tumor cells were spindle in shape with elongated nuclei. Some of tumor cells were arranged in a palisading fashion. Cell structures that resemble the Verocay bodies were observed. Some of the tumor cells showed pleomorphic bizarre nuclei, but no mitotic activity or chromatin clumping was seen. Inflammatory cells, siderophages and histiocytes were scattered in fibrillar material. These cytologic findings are important in the diagnosis of ancient schwannoma and in the differentiation of this tumor from the malignant spindle cell tumor.
