Recurrent peritoneal mesothelioma with long-delayed recurrence

Peritoneal mesothelioma is a rare malignancy with a poor prognosis. Etiology is unclear and presentation of this disease is often atypical. There are very few cases of long-term survival in patients with peritoneal mesothelioma. We report the case of a patient with peritoneal mesothelioma of 19 years' duration. To the best of our knowledge, there have been no reports of recurrent peritoneal mesothelioma with such long-delayed recurrence and survival. Recurrent peritoneal mesothelioma in the current patient was confirmed by comparing the biopsies of omentum taken in 1979 with that taken in 1997. An extensive literature search was undertaken to look for previous reports of recurrent peritoneal mesothelioma. Aggressive and intensive chemotherapy appeared to provide a longer survival time. Our patient had paraneoplastic manifestations that included paraneoplastic hepatopathy and a wasting syndrome. Peritoneal mesothelioma is a rare malignancy with one to two cases per million in the United States. It is known to exhibit unusual paraneoplastic manifestations, including paraneoplastic hepatopathy. Treatment is often unsuccessful, with a median survival time of approximately 18 months from diagnosis. A better understanding and aggressive management of this disease appear to help prolong survival.
