Malignant peritoneal mesothelioma is a rare disease and usually develops in individuals aged between 50 and 69 years. Exposure to asbestos is reported in 80% of cases of pleural mesothelioma, but in peritoneal type such an exposure is noted in only 8% of cases. Prognosis is poor for mesothelioma with a median survival of <1 year. Here, we report two cases of malignant peritoneal mesothelioma without history of exposure to asbestos.
