Sister Mary-Joseph nodule is an umbilical skin metastasis from a malignant tumor of abdominal origin. It is a rare and late clinical sign, indicative of an advanced stage of digestive or ovarian carcinoma. We report five cases of an umbilical skin metastasis revealing a colonic tumor in 3 cases and an ovarian tumor in two cases. Through five cases we want to describe the epidemiological, diagnostic, therapeutic and prognostic peculiarities of Sister Mary-Joseph's nodule.
