Atypical endometriosis in ovarian clear cell neoplasms^*

Adenofibroma	Atypical proliferative (borderline) tumor (n=6)	Carcinoma with adenofibromatous background (n=16)	Carcinoma without adenofibromatous background (n=57)	p-value†
-	1 (17%)	2 (13%)	25 (44%)	0.004

*, The denominator for all calculations is based on the number of patients in that group with typical or atypical endometriosis in the ovarian tumor

†, All adenofibromatous tumors combined (atypical proliferative [borderline] tumor + carcinoma with adenofibromatous background) vs. carcinoma without adenofibromatous background
