[Peritoneal mesothelioma: long-course ascites as the only clinical manifestation].

The mesothelioma is a rare tumor, especially in its peritoneal location (20%). Most of these cases are related to an exposition to asbestos long time age. We present a patient with long-evolution ascites and without any other clinical manifestations. The study of the ascitic fluid, the imaging techniques and the peritoneoscopy did not allow the diagnosis in the first place. Only after one year of follow-up and when the patient recalled, in a directed interrogation, her occupational contact with asbestos thirty years age, the diagnosis could be established.
