Osseous metaplasia in ovarian tumours: a case with serous cystadenoma

摘要

In a recent paper in the Journal of Clinical Pathology, Godbole et all reported a case of osseous metaplasia in a benign ovarian cyst in association with cloacal anomaly. These authors stated that only four published cases with osseous metaplasia in ovarian tumours exist, three in the literature, and the one they presented. The former three cases were associated with papillary serous carcinoma, the-coma and endometrioma in a supernumerary ovary, respectively.
