A Case of Cecal Cancer Diagnosed from Sister Mary Joseph's Nodule

A metastatic tumor of the umbilicus is called"Sister Mary Joseph's nodule", and patients with this tumor show a poor prognosis. Sister Mary Joseph's nodule is a rare occurrence, and there are few case reports. We report a case of cecal cancer first presented with the metastatic tumor in the umbilicus. A 90-year-old woman, complained umbilical induration and foul-smelling discharge, had been treated as omphalitis for 2 months. Because her symptom didn't improve, biopsy of the umbilical tumor was performed, and the findings revealed an adenocarcinoma. She was referred to our hospital. Abdominal CT showed wall thickening in the cecum, and multiple liver metastases. Therefore, we performed lower gastrointestinal endoscopy, which revealed a cecal tumor. We performed biopsy of the tumor and the findings were consistent with adenocarcinoma. Based on these results, we diagnosed the umbilical tumor as a metastasis from the colorectal cancer. Umbilical resection and ileocecal resection were performed, and multiple peritoneal metastases was detected. Post operative course was uneventful, she died 11 months after surgery. Umbilical metastases may worsen the patient's quality of life; thus, the local resection of umbilicus was recommended positively.
