Endometrioid carcinoma in pelvic endometriosis in a postmenopausal woman with tamoxifen adjuvant therapy for breast cancer. A case report.

This concerns a 57 year old woman operated on in 1988 for a left radical mastectomy due to ductal breast carcinoma and subsequently treated with chemotherapy and Tamoxifen adjuvant. In 1990 a laparo-hystero-oophorectomy was carried out due to uterine fibromas. The woman continued taking Tamoxifen. Two years later a pelvic regeneration appeared, resulting in endometriosis, site of adenomatose hyperplasia and of endometrioid carcinoma GI. This furthermore confirms the importance of a gynecological follow-up for all women treated with Tamoxifen adjuvant therapy.
