Plain-English summary
A 5-year-old male cocker spaniel was taken to the vet because of a mass on his penis, measuring about 1.3 cm. After examining the mass with a needle and looking at the cells under a microscope, the vet found that it was a type of tumor called an extramedullary plasmacytoma. This kind of tumor is rare in dogs. The diagnosis was confirmed through specific tests that showed the characteristics of plasma cells. Treatment options would typically involve surgical removal, and it's important for pet owners to discuss the best approach with their veterinarian.

Abstract
Penile tumours are rare in dogs. Reported herein is a case of a penile extramedullary plasmacytoma (EMP) in a 5-year-old male cocker spaniel that was brought to a local hospital for an evaluation of a penile mass. The mass was approximately 1.3 cm in diameter at the time of presentation. In fine needle aspiration and histopathological examinations, the neoplastic cells showed eccentric round nuclei, a moderate amount of basophilic cytoplasm, and a peri-nuclear clear zone, consistent with plasma cell morphology. There was nuclear pleomorphism with mononuclear giant cells and occasional bi-nucleation. Round cells on the periphery of the mass demonstrated plasmacytic differentiation. Immunohistochemically, the neoplastic cells stained positive for MUM1 and light lambda chain. Based on the cytological and pathological observations, a diagnosis of penile EMP was established.
