Multicystic peritoneal mesothelioma: report of three cases.
Multicystic peritoneal mesothelioma is a rare lesion occurring mainly in women in a reproductive age. Its pathogenesis is unclear. We report three cases of multicystic peritoneal mesothelioma in patients that were 28, 38 and 47 years of age (one male, two females). A history of abdominal surgery was reported in two cases. Explorative laparotomy was presumptive of a pseudomyxoma peritoni in two cases, and hyperthermic intraperitoneal chemotherapy was performed. Histological examination demonstrated multicystic lesions with mesothelial cells lining confirmed by immunohistochemical analysis. Unusual findings such as hyperplasia, hobnail features, cytoplasmic vacuolisation and papillary pattern were occasionally noted. The clinical presentation, pathogenesis and pathologic features including differential diagnosis of multicystic peritoneal mesothelioma are discussed.
