Plain-English summary
A 4-year-old neutered male cat was brought in with a mass near his penis. The vet performed surgery to remove the mass, which was diagnosed as a high-grade B-cell lymphoma, a type of cancer. After the surgery, the cat was free of disease for six months but unfortunately passed away later from an unknown cause. This case highlights that while penile lymphoma is rare in cats, it should be considered when there are masses in that area, and surgery can help manage it.

Abstract
A 4-year-old neutered male cat was presented with a perineal mass extending over the penis. The mass was surgically excisedperineal urethrostomy. Histopathology confirmed a high-grade B-cell lymphoma confined to the penis and extending microscopically to the prepuce. The cat remained disease free for 6 mo before dying of an unknown cause. To the authors' knowledge, this case may represent the first reported instance of a feline lymphoma clinically confined to the penis. Key clinical message: Penile lymphoma, though rare in cats, should be considered in the differential diagnosis for perineal or penile masses. Surgical excision can achieve local control, but prognosis and the role of adjuvant therapy remain uncertain.
