Benign multicystic peritoneal mesothelioma: A rare case presenting as pneumoperitoneum and pneumotosis intestinalis.

Abstract

Benign multicystic peritoneal mesothelioma (BMPM) is a rare peritoneal lesion that commonly presents as lower abdominal pain, palpable mass, or both. A case of BMPM presenting as pneumoperitoneum and pneumotosis intestinalis is described. Utilizing PubMed, a review of the literature was performed using the search words “benign multicystic peritoneal mesothelioma,” “multilocular peritoneal inclusion cysts,” “pneumoperitoneum,” and “pneumotosis intestinalis.” Although this lesion is typically benign, it has a high recurrence rate as well as the potential for malignant transformation; it is important to confirm the diagnosis in a minimally invasive manner, and to formulate a surgical treatment strategy to avoid unnecessary re-operations.
