[A Case of Sister Mary Joseph's Nodule from Multiple Colon Cancers]

A 94-year-old woman, who had been treated for multiple colon cancers 4 years ago, complained of umbilicus induration and had been followed up in a previous hospital with a diagnosis of periumbilical inflammation. Four years and 3 months postoperatively, the umbilical induration was enlarged, and umbilical metastasis of adenocarcinoma was diagnosed on biopsy. Umbilical resection was performed, and multiple peritoneal metastases were revealed. Umbilical metastases may worsen the patient's quality of life; thus, local resection was recommended positively.
