Sister Mary Joseph's Nodule Revealing Klatskin's Cholangiocarcinoma at the Yalgado Ouedraogo University Hospital: Case Report and Literature Review

Umbilical cutaneous metastases of abdomino-pelvic tumors are rare. They are known as Sister Mary Joseph nodules. The presence of this nodule indicates an advanced cancerous lesion and is associated with a poor prognosis. Because of its rarity, the Sister Mary Joseph nodule can go unnoticed. Its discovery should prompt a skin biopsy and abdomino-pelvic cross-sectional imaging. The occurrence of a Sister Mary Joseph nodule secondary to cholangiocarcinoma is rare. The aim of our work was to present a case of umbilical cutaneous metastasis revealing a Klatskin's cholangiocarcinoma in the Hepato-gastroenterology department of the Yalgado Ouedraogo University Hospital (CHU YO).
