A Rare Form of Mesothelioma: Malignant Pleural Deciduoid Mesothelioma

Mesothelioma usually develops in elder male patients that are exposed to asbestos. Deciduoid mesothelioma is a rare variant of epithelioid mesothelioma and has a poorer prognosis than epithelioid mesothelioma. As this subtype was seen in the peritoneum of young females and its relation with asbestos was not definite, these lesions were formerly thought to be stimulated by endogenous hormones. In the subsequent years, a relation was established between this tumor and asbestos since it was seen in the pericardium and pleura of males. In this paper, we present a 64-year-old male patient with asbestos exposure, diagnosed as having malignant pleural deciduoid mesothelioma, in which a long survival was provided with chemotherapy after surgery.
