title: Mucinous adenocarcinoma of the umbilicus 8 years following anterior resection for villous adenoma of the rectum.
abstract: We present the case of an 80-year-old retired consultant histopathologist who presented to us with a malignant umbilical mass 8years following resection of a sigmoid adenoma. The report details initial investigation and management of the umbilical mass and the subsequently discovered pelvic recurrence. Our conclusions of its origin, as a malignant transformation due to seeding of the original sigmoid adenoma, show the slow progression of some colorectal tumours; and the importance of obtaining a complete specimen intra-operatively.
