The benign multicystic peritoneal mesothelioma is a rare disease. Most frequently, young women in reproductive age are affected by this disease. Nevertheless, there are known cases of multicystic peritoneal mesothelioma in male patients. The pathogenesis remains uncertain. Whereas asbestos fibers can cause the development of malignant mesothelioma, the exposure to asbestos particles cannot induce this type of mesothelioma. An inflammatory genesis is discussed as well as the idea of a neoplastic development. Since a high rate of recurrence after surgery is observed, an aggressive surgical treatment is recommended. The complete resection of affected tissue is recently considered to be the therapy of choice. The combination of complete surgical tumor reduction with an intraperitoneal hyperthermic chemotherapy (HIPEC) seems to be promising. Although malignant transformation is detected very rarely a close follow up in centers with high surgical and oncological expertise is recommended.
