Epidermal inclusion cyst is the one of the common benign tumors of vulvar area. It can result from vulvar skin trauma such as vaginal wall sling operation and female mutilation etc. causing an invagination of squamous epithelium, which then desquamates into a closed space to form a cystic mass. We have experienced one case of huge epidermal inclusion cyst at rectovaginal and posterior coccygeal area considered of huge retroperitoneal mass, which is presented with a brief review of the literatures.

Pyelocaliceal diverticula are eventuations of the upper collecting system, lying within the renal parenchyma and communicating with the main collecting system via a narrow channel. They are smooth-walled and are lined by transitional cell epithelium. Their lining is nonsecretory but they contain urine derived by passive filling from the adjacent collecting system. The vast majority of these lesions are small, measuring below 1cm in diameter. A pyelocaliceal diverticulum containing multiple sandy stones is presented with review of literature.

Congenital prepubic sinus(CPS) is an extremely rare congenital anomaly of the external genitalia of uncertain etiology. Herein, a case of CPS, where immunohistochemical staining was performed to elucidate the etiology of the sinus, is reported. The results of the immunohistochemical study demonstrated the lining epithelium was transitional proximally and squamous distally. These findings suggest that CPS is a variant form of dorsal urethral duplication.

Pyelo-caliceal diverticulum refers to a cystic cavity containing urine the renal parenchyme, which is lined by transitional epithelium and communicates with the renal pelvis or a calyx through a narrow channel. Pyelo-caliceal diverticulum is a relatively uncommon entity and are usually quite small in size, averaging 0.5 cm to 5cm. Huge pyelo-caliceal diverticulum is presented with review of literatures.

I experienced a case of a congenital intramural cyst of the uterine fundus. It was composed of a single layer of non-ciliated low cuboidal epithelium without associated with endometrial stroma and was found to be derived from the mesonephric duct. This case is presented with a brief review of the literature.

An unusual case of glioependymal cyst radiographically simulating arachnoid cyst is reported. The cyst wall contained not only ependyma-like epithelium but also neuroglial tissue. The possible pathogenesis of this lesion is discussed.

To investigate the involvement of expression of the Fragile Histidine Triad(FH1T) gene product in the process of carcinogenesis and progression in cervical carcinoma, we examined its expression by immunohistochemical method in 15 cervical invasive carcinomas, 10 low grade cervical intraepithelial neoplasias(CINs) and 30 high grade CINs(CMI and III). We detected expression of FHIT gene product in 4 of 15(27%) of invasive carcinomas, 3 of 10(30%) low grade CIN and 7 of 30(23%) of high grade CIN, while we detected expression of FHIT gene product in 28 of 45(62%) normal and metaplastic epithelium near the tumor. Thesc data indicate that loss of expression of FH1T gene product has some role in the early tumorigenesis of uterine cervical carcinoma, but not the consequence of the pregression of the tumor.
