A rare cause of prepubertal scrotal swelling; Mature Cystic Teratoma

In this report we aimed to present a case with testicular mature cystic teratoma via clinical, surgical, and histopathological findings. A 10-years-old boy complaining of left scrotal swelling for the last two years admitted to our department. Physical observation revealed a painless, firm, smooth surfaced scrotal swelling. The distention of the left hemiscrotum did not allow the palpation of the testicle. At the preoperative period the case was considered as a non-communicating hydrocele. Surgical exploration was done via a left sided inguinal incision. Surgical exploration revealed a thick capsulated mass with a diameter of 10x8x6 cm. The mass was containing hairy pieces, gelatinous fluid and tooth like calcifications no testicular tissues present. The mass was totally excised. Histopathological examination of the specimen revealed a mature cystic teratoma. If testes could not be palpated or the swelling of the scrotum could not allow making the physical examination, mature cystic teratoma that is a rare cause of testicular mass should be considered.
