Recurrent endometrial cancer arising in the round ligament.

An unusual case of recurrent endometrial carcinoma presenting as a round ligament metastasis is discussed. The primary lesion detected six years earlier was a well-differentiated lesion with less than 50% myometrial invasion located in the fundus. A persistent inguinal swelling represented a metastasis to the round ligament. Histologic examination revealed a poorly differentiated adenocarcinoma. Patients with early stage well-differentiated endometrial carcinoma are not immune from late recurrence.
