Abstract:
Incomplete polyorchidism (also called bilobed testicle) is an extremely uncommon congenital anomaly. Only 3 cases of bilobed testicle were previously reported in the available literature. We describe a case of a 4-year-old boy who presented with a 6-month history of an asymptomatic scrotal mass located in the upper pole of the left testicle mimicking testicular tumour. After partial orchiectomy, macroscopic and pathological examination of the lesion confirmed the diagnosis of normal testicular tissue.
