The microscopic appearances were thoseof the diffused form of carcinoma {see Fig. 385). Macroscopically two principal groups are distinguishable : (1) thecystic adeno-carcinoma, and (2) the solid carcinoma. (1) The cystic adeno-carcinoma corresponds in its naked-eye 676 GYNECOLOGY characters to a benign cystic adenoma, and it is often necessary tomake a most careful, histological investigation before its malignancyis discovered. It occurs as a multilocular cystic tumour (see Fig. 381),containing, as a rule, inverting or papillary growths and a fluid whichvaries within very wide limits, but which frequently consists largelyof pseudomucin. When apparently solid, very soft, brain-like, whiteor yellowish areas appear in a multilocular cyst, the latter should be. Fig 382 Cystic ADENO-CARcmoMA of Ovaky.

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 coars
