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.

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.

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.

This experiment was aimed to investigate the contractile responses of the fermoral artery to the electrical stimulation and the inhibitory effects of verapamil and papaverine on the electrical stimulation of the fermoral artery in the control (n=46) and the diabetic rabbits(n=40). Diabetic rabbits were made by and administration of alloxan (100 mg/kg) intravenously and sacrified 8 weeks later. Femoral arterial rings 3 mm in length were taken and mounted on the force-displacement transducer for the measurements of isometric tension. All experiments were done in the aerated (95% O2 with 5% CO2)biological chamber filled with Kreb's solution and the initial tension of 1.5g was applied to the rings. After 1 hour of equilibrium of the rings, the contractile responses of the electrical stimulation on the femoral arterial rings were taken without vasoactive drugs and then, under verapamil and papaverine solution. And we compared the morphologic findings of the vessels in the two groups in relation to the functional changes by transmission electron miroscopy. The results are as follows: 1. The contractile responses in the presence of verapamil or papaverine solutions to the electrical stimulation were lowed significantly in the fermoral arterial rings of the diabetic rabbits compared with that of the control rabbits (verapamil; 10M~10M: p<0.01, papaverine; 10M & 10M: p<0.01). 2. Transmission electron microphotographs showed many morphological differences of the femoral arteries between the control and the diabetic rabbits. These were irregularities of the internal elastic lamina and the hypertrophy of the cytoplasms of the smooth muscle cells. And also, there were many vacuoles in the cytoplasm of the endothelial cells, lateral to the internal elastic laminaes, and between the smooth muscle cells in the diabetic rabbit femoral artery. By this study, we found that the contractile responses of the femoral arterial rings to the electrical stimulation were decreased in the diabetic rabbits, and the vasodiatory effects of verapamil and papaverine on the electrically stimulated femoral arterial rings were also lowered in the diabetic rabbits compared with the control rabbits. These changes of the vasular responses of the diabetic vessel may be associated with morphological changes manifested by transmission electron microscopy or any other functional derangement of the vessels.

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.

OBJECTIVE: To evaluate the perinatal prognosis of fetuses with a single umbilical artery. METHODS: From 1992 to 1998, nineteen cases with single umbilical artery(SUA) was observed in 8,704 deliveries at Chonnam University Hospital. RESULTS: Out of nineteen fetuses, thirteen fetuses with single umbilical artery were detected by antenatal ultrasonographic examination and six fetuses were detected after birth. The male to female ratio was 0.9: 1. Congenital malformations were observed in 8 babies(42.1%) and included leg deformity, esophageal atresia, imperforated anus, ventriculomegaly, meningocele, hydronephrosis, ventricular septal defect, joint contracture, cleft lip and palate, toe anomaly, imperforated anus, kyphosis, no urethra and testis, clubfoot, patent ductus arteriosus and rnild mitral regurgitation. Among 10 cases of karyotyping analysis three cases were diagnosed as trisomy 18. Fourteen fetuses(77.8%) showed growth restriction at delivery. Antenatal obstetric complications were hydramnios(n = 3), oligohydramnios(n =2), and severe preeclampsia(n = 3). CONCLUSION: Careful ultrasonographic evaluation for the identification of a SUA is necessary because of its frequent association with congenital anomaly, growth restriction and cytogenetic abnormality.
