title: Cholangicarcinoma Presenting as a Sister Mary Joseph Nodule.
abstract: Sister Mary Joseph nodules represent metastatic cancer of the umbilicus. More than half of these cases are attributable to gastrointestinal malignancies including gastric, colonic, and pancreatic cancer. In addition, gynecologic (ovarian, uterine cancer), unknown primary tumors, and, rarely, bladder or respiratory malignancies may cause umbilical metastasis. We report the case of a Sister Mary Joseph nodule originating from a hilar cholangiocarcinoma. Umbilical nodules should prompt clinical evaluation, as these tumors are usually associated with poor prognosis.
