title: Unilateral pelvic mass presenting in postmenopausal patients: report of two unusual cases.
abstract: We encountered 2 unusual cases of polypoid endometriosis presenting as unilateral ovarian masses. The first was benign and was found in a 57-year-old postmenopausal patient; the second case gave rise to well-differentiated endometrioid carcinoma in an 80-year-old patient. The second patient also had a superficially invasive endometrioid adenocarcinoma of the endometrium arising in a background of complex atypical hyperplasia. Intraoperative evaluation was requested in both cases.
