J Med Primatol. 2024 Dec;53(6):e70001. doi: 10.1111/jmp.70001.

Abstract

A free-ranging capuchin monkey developed a synchronous biphasic pleural and peritoneal mesothelioma, a rare form of this tumor. Exophytic nodules were dispersed over the serosal surfaces, showing marked microscopical malignant features composed of both epithelioid and spindeloid neoplastic cells immunopositive for Pan-Cytokeratin, Cytokeratin 5/6, Vimentin, WT-1, and D2-40.

Keywords: abdomen; capuchin monkey; mesothelial tumor; neoplasm; nonhuman primates; thorax.
