ABSTRACT

Polyorchidism is a very rare congenital disorder. We report triorchidism in a 20-year-old man who presented with pain in the right inguinal region. We palpated a mass near the penile corpus and superior of the right testis. Ultrasonography (USG) revealed a mass near the root of the penis in the right scrotum measuring 22*18*31 mm. Scrotal magnetic resonance imagination (MRI) showed normal left and right testes and a isoinstance third testis between both of them. Testosterone, follicle-stimulating hormone (FSH), luteinizing hormone (LH), beta human chorionic gonadotropin (BHCG), and alpha fetoprotein (AFP) were within the reference range. Semen analysis showed no abnormality. The findings were compatible with the diagnosis of testicular duplication. The patient was followed up conservatively.

If the testis is located in the scrotum and testicular tumor markers are negative, surgical exploration or biopsy is not necessary. USG and MRI also help distinguish between testicular and extratesticular pathologic processes and determine the solid and cystic lesion. Following up conservatively is enough. Location of the supernumerary testis in the abdomen or inguinal region carries the risk of testicular cancer; so, orchiectomy is required. (JAREM 2014; 2: 77-8)
