Bilateral Diffuse Leydig Cell Tumour of Testicles in a Golden Retriever Dog

Abstract

A seven year old male Golden Retriever dog was presented with a history of unilateral scrotal swelling noticed for the last 20 days. The animal was obese and without any clinical signs. Physical examination revealed hard, freely movable enlarged and painless right testicle and hard and nodular left testicle. Ultrasonography revealed circumscribed, hypoechoic and irregular masses within the parenchyma of both testicles suggesting tumour of the testicle. Bilateral orchiectomy was performed as per standard surgical procedure under general anaesthesia. The animal had an uneventful recovery. Histopathology of tumour mass revealed diffuse Leydig cell tumour of both testicles.
