Deciduoid mesothelioma is a rare variant of epithelioid mesothelioma. We experienced the case of a 73-year-old man with asbestos exposure who was diagnosed with malignant pleural mesothelioma with deciduoid features. He received chemotherapy containing six cycles of cisplatin and pemetrexed and survived for twenty-five months after the diagnosis. At autopsy, the final diagnosis was biphasic pleural mesothelioma. Cells with deciduoid features had mostly disappeared, and spindle cells markedly proliferated. To the best of our knowledge, this is the first autopsy case of malignant pleural mesothelioma with deciduoid features that exhibited a response to chemotherapy.

D008654 Mesothelioma A tumor derived from mesothelial tissue (peritoneum, pleura, pericardium). It appears as broad sheets of cells, with some regions containing spindle-shaped, sarcoma-like cells and other regions showing adenomatous patterns. Pleural mesotheliomas have been linked to exposure to asbestos. (Dorland, 27th ed) Mesotheliomas
D010997 Pleural Neoplasms Neoplasms of the thin serous membrane that envelopes the lungs and lines the thoracic cavity. Pleural neoplasms are exceedingly rare and are usually not diagnosed until they are advanced because in the early stages they produce no symptoms.

D000086002 Mesothelioma, Malignant A type of mesothelioma with a tendency to metastasize. Most tumors originate from either the PLEURA or PERITONEUM, tumors may also originate in the PERICARDIUM or testicular tissue. It is associated with ASBESTOS exposure. Somatic mutations identified in WT1, BCL10, CDKN2A, NF2, and BAP1 genes are associated with the malignancy. OMIM: 156240.
