Urethral stricture usually follows the urethral rupture and periodical urethral soundation, which is an annoying procedure for. patients, is the usual method of treatment throughout their life. A case of urethral stricture who was successfully treated with modified Cecil's Operation, is presented.

OBJECTIVE: The purpose of this article is to report mixed germ cell tumor, which revealed changes compatible with early transformation of dysgerminoma to endodermal sinus tumor(EST) through histogenetic considerations and immunohistochemical stains. METHODS: Ovarian germ cell tumors were reviewed from files of Dept. Ob/Gyn. Seoul Paik Hospital fiom 1992.1 to 1996.12. Total of 5 cases include 4 pure dysgerminoma and 1 mixed germ cell tumars. All tissues were fixed in 10% neutral buffered formalin and embedded in paraffin and reviewed by two pathologists with immunohistochemical staining for cytokeratin, vimentin, AFP, PCNA, p53 & bc1-2. RESULTS: Grossly, the areas of transformation were located at the middle of the mixed tumor. The outer layer of the tumor mass was filled with typical pure dysgerminoma. They were characterised as the presence of microcysts and small glandular structures in hematoxylin-eosin(H-E) stains with positive stain for vimentin, except the tissue of the EST. The cells in the intermediate layer were characterised as the mixed form of dysgerminomatous and EST structures in H-E stains. AFP in the dysgerminomatous cells in intermediate layer and EST were stained, but not in outer layer. CONCLUSION: Dysgerminoma may possess the ability to transform to EST. There might be intermediate stage between dysgerminoma and EST, and Immunohistochemical staining for AFP, cytokeratin, vimentin, PCNA also can be used for prognosis of germ cell tumor.

Developing the instruments in urological field, the urinary tract stones may be manipulated more easily and lesser invasively recently. The percutaneous nephrolithotripsy is one of the most widely using technique for the renal stone. But, the major portion of the failure through the manipulation of percutaneous nephrolithotripsy is the access to the correct, wanted calyx by puncture. So, we observed the 27 normal right kidneys and 26 left kidneys by abdominal computer tomogram scanning and excretory urography for the Korean caliceal anatomy. The following results were obtained 1. The average values of posterior renal rotation from the coronal plane of body were 31.0 degrees +/- 4.4 degrees in the right kidneys 32.4 degrees +/- 3.2 degrees in the left kidneys. 2. The average values of anterior and posterior caliceal angle were 58.8 degrees +/- 7.6 degrees and 20.7 degrees +/- 5.8 degrees in the right kidneys; 38.3 degrees +/- 6.2 degrees and 43.0 degrees +/- 5.2 degrees in the left kidneys. 3. The major type of classical system was Brodel type (74.l%) in the right kidney; Hodson type (53.8%) in the left kidney. 4. The anterior calyx is more laterally placed about 8l.8% in the excretory urography.

Ewing's sarcoma is a highly malignant, small, round cell tumor that usually affects long bones. The acral part of the extremities is a very rare primary site for this neo plasm. A fifteen-year-old girl was seen for a lobulated, dome-shaped, 2.7cm diameter, denuded mass on the distal phalanx of the right middle finger which had increased in size over a 14-month period. The radiological featuies of the hand showed a cortical brick of distal phalanx and surrounding soft tissue mass. Histologically, the biopsy specimen showed sheets of small round to oval cells with scanty cytoplasm, that were closely packed and separated into lobules by trands of fibrous tissue. A periodic acid-Schiff stain demonsirated glycogen in the cytoplasm of the tumor cells. Electron microscopy showed large aggregates of glycogen in the cytoplasm of the neoaplastic cells. Immunohistochemical stains revealed positive staining for vimentin, glial fibrillary acid potein, and neuron specific enolase, stains for S-100, Factor VIII, and cytokeratin were negative.

The term endometriosis refers to ectopic endometriume. It most often involves the pelvic organs, including ovaries, broad and round ligaments, fallopian tubes, cervix, vagina and the pouch of Douglas. We report a case of vesical endometriosis in a 4- year old female patient and review literature. Segmental resection of this mass with involved bladder resulted in cure and this lesion was confirmed histologically as endometriosis of the bladder.
