[PUBERTAL TESTICULAR TORSION OF POLYORCHIDISM DIAGNOSED IN INFANCY: A CASE REPORT].

Left polyorchidism was found in a 2-month-old boy with a left scrotal mass. As he was asymptomatic and all testes were in the scrotum, he was conservatively followed up. At 17 years of age, he presented with left acute scrotum due to testicular torsion of the left supernumerary testis. Counterclockwise 720-degree rotation of the left supernumerary testis was noted during emergency surgery, and orchidopexy of the 3 testes (2 left testes and 1 right testis) was performed. Biopsy of the left supernumerary testis demonstrated spermatogenesis and no malignancy. One and a half years after surgery, all testes were viable without atrophy.Polyorchidism is a rare condition and there is no consensus on the management of asymptomatic cases detected early in life. The position of the supernumerary testis (intrascrotal or extrascrotal) is important when deciding the management strategy because of the risk of malignancy. If conservative management is selected initially, elective surgery, such as prophylactic orchiectomy or orchidopexy, may be needed because of the risk of malignancy and torsion.
