Supernumerary testicle in a case of polyorchidism.

Introduction: The presence of more than 2 testicles is called polyorchidism. It is a rare anomaly. Less than 100 cases have been reported in the literature. Clinical Picture: A 51-year-old man complained of a painless right groin lump for a year. Physical examination revealed a discrete ovoid non-tender, firm but mobile lump. No cough impulse was demonstrated. Sonography demonstrated a soft tissue structure within the tunica vaginalis inferior to the deep inguinal ring. It demonstrated similar echotexture and vascular flow as the normal testis, but smaller in size. The findings were compatible with a diagnosis of polyorchidism. Treatment: The patient was not keen for surgery and was followed up conservatively. Conclusion: Differential diagnosis of a solid extratesticular mass should include polyorchidism.
