Multiple hepatic cavernous lymphangioma in an aged male cat

A 10-year-old male Domestic Longhair cat with weight loss, enlarged left testicle, icterus and mild liver enlargement showed, at necropsy, two white, raised, firm, circumscribed masses in the liver and striking enlargement of the left testicle. The histological features of the liver masses were consistent with lymphangioma. Severe, diffuse, coalescing to multifocal, subacute, necrotizing orchitis of the left testicle also was diagnosed. A literature review and examination of the epidemiology of lymphangioma in small domestic animals demonstrated the rarity of this tumour in cats.
