Sister Mary Joseph Syndrome: A Report of a Rare Case.

The Sister Mary Joseph syndrome is characterized by cutaneous metastases localized at the umbilical level. It is a rare clinical sign estimated to occur in 1%-3% of patients with abdominopelvic cancer. The most common histology is adenocarcinoma (75% of cases). The presence of this nodule is often indicative of a poor prognosis, with average survival estimated at two to 11 months without treatment. We report the clinical case of Sister Mary Joseph syndrome in a 50-year-old woman who had been followed for three years for endometrioid adenocarcinoma of the endometrium. The diagnosis was established via umbilical biopsy after a computed tomography scan revealed the presence of an umbilical nodule. The patient is currently undergoing a palliative chemotherapy regimen.
