Benign cystic mesothelioma in a male patient: surgical treatment by the laparoscopic route.

We report a case of a benign cystic mesothelioma in a 44-year-old man. The patient was asymptomatic, and the cystic formation was discovered by chance in the course of ultrasonography for urological disorders. Benign cystic mesothelioma is a rare pathology, and only 19 cases have been described in male patients. The differential diagnosis versus other cystic diseases can only be defined histologically and is of critical importance to clinical management. Surgery is mandatory for both diagnosis and treatment. In the case reported here, a minimally invasive laparoscopic approach allowed not only histological diagnosis of benign cystic mesothelioma, but also its surgical treatment by the same route.
