Insights
This is the first reported case of feline lymphoma confined to the penis. Surgical excision achieved local control, but the cat
Area of Science:
- Veterinary Medicine
- Oncology
- Feline Health
Background:
- Perineal and penile masses in cats can present diagnostic challenges.
- Lymphoma is a common cancer in cats, but typically affects lymphoid tissues.
- Limited information exists on feline penile lymphoma.
Abstract:
A 4-year-old neutered male cat was presented with a perineal mass extending over the penis. The mass was surgically excised via perineal 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.
