Abstract

Histopathologic features of ovarian clear cell carcinoma (CCC) which are not in themselves diagnostic but are very common include the presence of oxyphil cells (prominent in 25–30 % of cases) and of endometriosis (found in the tumor-bearing ovary in 43 % of our cases, in most of which a direct origin of CCC could be demonstrated). The endometriosis was at least focally atypical in 69 % of the cases. Other findings in ovarian CCC which were either less specific and/or less common included signet ring cells, stromal inflammatory infiltrates/necrosis/cholesterol clefts/fibrosis, stromal edema or mucinous material, clefts around tumor cell nests, tumor multinodularity, thanatosomes, and foci of calcification with or without psammoma bodies and rarely ossification.
