Gynaecology for students and practitioners . ngle layer of columnarepithelium of benign adenoma is replaced by many layers of cancerous cells. regarded with suspicion and should be examined microscopically forevidence of malignancy. Cystic adeno-carcinoma can occur primarily, or may be the result ofa malignant change in a hitherto benign cyst. In either case there maybe numerous cysts lined by a single layer of columnar epithelium, lyingin proximity to other cysts in which are seen many layers of irregularlyshaped epithelial cells, filling up the lumina in characteristic malignantfashion (see Fig. 382). In the metastases also, simple and malignantglandular structures exist side by side, while the benign elements con-tinue the function of secretion. The type of papillary cancer derived from a papilliferous serouscyst was shown in Figs. 378, 379, 380 (pp. 672-674). (2) The solid carcinoma. In the second group, the carcinomataform solid coarsely lobulated tumours with a well-formed pedicle (see Fig. MALIGNANT EPITHELIAL TUMOURS 677. 678 GYNECOLOGY 383).
