Background: Polyorchidism is an extremely rare congenital anomaly of the urogenital system and is defined as the presence of more than two testes. The majority of patients are asymptomatic or present with painless inguinal or scrotal masses. We, hereby, report a 25-year-old triorchidism case who presented with testicular pain and a scrotal mass. Case report: A 25-year-old male patient was admitted to the outpatient clinic with the complaint of testicular pain and a scrotal mass. His medical history was unremarkable and there was no history of trauma. On physical examination, there were two palpable, ovoid, mobile, non-tender masses in the left hemiscrotum. Scrotal Color Doppler Ultrasonography revealed a 1.5 × 2.0 × 1.2 cm, well-circumscribed accessory tissue in the left hemiscrotum which had same echogenicity as the normal testes. Magnetic Resonance Imaging (MRI) also confirmed the tissue as the third testis. The patient was managed conservatively and put into a follow-up program.
