Endometrial metastasis from signet-ring breast carcinoma: case report.

Breast cancer rarely metastasizes to the endometrium. The signet-ring variety of breast cancer is very rare and has been reported to metastasize to the endometrium in only three previous reports. We present a patient with signet-ring breast carcinoma with metastasis to the endometrium. The patient presented with vaginal bleeding and was found to have wide spread metastasis. Endometrial metastasis in patients with signet-ring breast cancer usually denotes a poor prognosis.
