Malignant mesothelioma is an uncommon tumor that usually arises in the pleural cavity of adults with a history of asbestos exposure. Less frequently, it appears in the peritoneum or other mesothelial surfaces. Deciduoid mesothelioma is a rare subtype that has been found in both sites. Of the three reported cases in children, two originated in the mesenterium and one in the pleura. We describe a fourth case of pediatric malignant deciduoid mesothelioma, and the third in the mesenteric cavity. The patient was an 8-year-old girl who presented with abdominal pain and fullness. Work-up revealed extensive involvement of the abdomen by a serosa-based tumor. The clinical and pathologic findings are described, and the pertinent literature is reviewed.
