Quadriorchidism: A case of bilateral supernumerary testicle and review of the literature

Polyorchidism, which means one or more additional testicles, is a congenital anomaly and is seldom observed. In many polyorchidism patients, there is one supernumerary testicle (SNT) (triorchidism) whose left face is often the presentation. Two-sided SNT is very rare, and has been reported only in six cases. Here, we are presenting a male case who was six years old with bilaterally SNT (quadriorchidism) in scrotum that presented as asymptomatic masses.
