Peritoneal malignant mesothelioma: case report.

Our study reports peritoneal diffuse malignant mesothelioma (DMM) in a 43 years old male patient, with no exposure to asbestos in his medical history; the partner of the patient was also not exposed to asbestos. The exposure to X-rays was also excluded. Different pathogenic mechanisms for the pathogenesis of a peritoneal diffuse malignant mesothelioma in this patient can be hypothesized, for example, SV40 infection and genetic susceptibility; a minimal domestic exposure to asbestos can be not excluded. Therefore, further studies in a larger number of subjects are necessary to determine whether one or all of these hypothetic pathogenic mechanisms are more significant for the development of malignant mesothelioma.
