A case of multicystic peritoneal mesothelioma

Abstract

Multicystic peritoneal mesothelioma is an unusual mesothelial lesion that deserves separate consideration because of its characteristic histologic picture and its benign behavior. In the past, this lesion was often confused with cystic lymphangioma, mesenteric lymphatic cyst, diffuse mesothelioma, and disseminated form of mucin-producing adenocarcinoma. Diagnostic accuracy and long-term follow-up are needed due to high incidence of recurrence. We report a rare case of huge multicystic peritoneal mesothelioma in a 36-year-old woman. At follow-up 18 months after surgery, the patient remained asymptomatic with no further growth.
