Cysts of accessory lacrimal gland are rare. They are generally retension cysts that result from obstruction of the excretory duct and are found between the palpebral conjunctiva and the levator aponeurosis. We experienced three cases of subconjunctival cyst in the upper fornix. Histopathological examination showed the cysts lined by two layers and occasionally one layer of epithelium. These cysts seem to be originated from Krause's gland, considering their anatomical location and histopathological findings.

The corneal rust ring is made artificaily by anexperimental method on the rabbit and the fate of the rust ring is observed by SEM for the interval of 1 week to 3 months. Because of the shortness of the observation period, the complete natural process of removal of the corneal rust ring can not be fully explained. But several interesting results can be obtained by this experiment. The implanted iron particles are falled off by the natural healng course without articial removal in three weeks. The rust ring can be detected on the corneal epithelium 21 days after implantation and continued until 3 months and moreover, by the SEM examination. Many PMNs and macrophages are present in the vicinity of the rust ring until 35 days and decrease gradually thereafter. The presence of these inflammatory cells reveals that these inflammatory cells reveals that these cells can take part in the process of the removal of the iron rust rings formed on the superficial eornea.

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.

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.

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.

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.
