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.

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.

Primary papillary serous carcinoma of the peritoneum(PPSCP) is vere rare. It has been suggested that PPSCP derives from embryonal coelomic epithelium with m llerian ducts potential. PPSCP can develop from a single or multicentric focus. The clinical and histologic disease entities are similar to those of primary papillary serous carcinoma of the ovary, but PPSCP involves the ovarian surface only minimally(microscopic disease) or spares the ovaries entirely. We have experienced a case of primary papillary serous carcinoma of the peritoneum and report this case with brief review of the concerned literature.

Folliculosebaceous cystic hamartoma(FCH) is a rare tumor of characteristic clinical and histological features. Histological findings are intradermal cystic structures lined by infundibular epithelium, numerous sebaceous lobules radiating from cystic structures and surrounding stroma composed of mesenchymal changes including variable proportions of fibrous, adipose, vascular and neural tissues. We describe a case of FCH associated with perifollicular mucinosis, which is unusual finding.
