Core tip: Malignant peritoneal mesothelioma is a rare aggressive tumor of the peritoneum. We performed laparoscopy which showed specific laparoscopic findings, and the pathological findings of the biopsy specimen led to the diagnosis. This case was associated with umbilical hernia and umbilical metastasis, which is also called as Sister Mary Joseph’s nodule.
