Cystic neoplasms of the exocrine pancreas.
(78/165)
Cystic neoplasms of the pancreas are rare and their diagnosis and treatment can be difficult. This report details 7 patients who had histologically proven serous cystadenoma, mucinous cystadenoma and cystadeno carcinoma. Computed tomography and sonography allowed excellent preoperative assessment but to attempt a distinction between the histological variants may be hazardous. Two tumours were only autopsy findings and 5 patients underwent laparotomy. It is confirmed that potentially malignant mucinous cystadenomas and cytadenocarcinomas should be resected whenever possible; serous cystadenomas are always benign and should therefore be resected only when the diagnosis is doubtful or if they cause symptoms.

An immunohistochemical study of distribution of carcinoembryonic antigen in epithelial tumours of the ovary.
(79/165)
An immunohistochemical study of the tissue CEA content of 82 epithelial neoplasms of the ovary has shown that mucinous tumours contain more of this substance than do their serous counterparts; otherwise a knowledge of tissue CEA content appears to be of little value in the differential histological diagnosis of this group of neoplasms. Among mucinous tumours there is only a partial correspondence between their degree of malignancy, as assessed histologically, and their content of CEA. It is postulated that immunohistological study of tissue CEA may add a degree of finesse to morphological analysis of these neoplasms and thus allow for a more precise grading of their degree of malignancy.
