Primary umbilical adenocarcinoma: case report and review of the literature.

Primary adenocarcinoma arising at the umbilicus is a very rare condition. The umbilicus has been found to show a wide variety of tumors and is predisposed to metastases from visceral tumors because of its relationships and generous vascular and embryologic connections. Herein, we describe a case of a primary umbilical adenocarcinoma with short time survival related to local recurrence and multiple hepatic metastases 6 months after her surgical treatment.
