The paper presents a single ovarian case in which clear cell adenocarcinoma and squamous cell carcinoma coexisted adjacent to each other but were not admixed. Ovarian endometriosis was confirmed concurrently, and histology showed the clear cell component contiguous with atypical monolayered glandular cells, while the squamous component was associated with squamous metaplasia with cellular atypia. The authors concluded that the two malignancies arose independently from the ovarian endometriosis, noting they believed it to be the first report of this specific coexistence pattern. This paper is centrally about endometriosis — it reports coexisting ovarian clear cell adenocarcinoma and squamous cell carcinoma arising from confirmed ovarian endometriosis.

Abstract A case of clear cell adenocarcinoma and squamous cell carcinoma coexisting in the ovary is presented. These two malignancies were adjacent but were not admixed, and ovarian endometriosis was confirmed concurrently. The clear cell adenocarcinoma was contiguous to monolayered glandular cells with cytological and architectural atypia, while squamous metaplasia with cellular atypia was observed adjacent to the squamous cell carcinoma. We concluded that these two malignancies arose independently from ovarian endometriosis. To our knowledge, this is the first report of such a case.
