The ectopic position of the testis is defined by a migration differing from the normal descent into the scrotum. This error is due to an anomaly of fixation of the distal extremity of the gubernaculum testis (2), resulting in an abnormal position of the testis. The five major sites of ectopic testis are the superficial inguinal canal (most frequent), femoral canal, suprapubic region (at the base of the penis), contralateral scrotum (rare) (3) and, lastly, the perineal region, which is also rare (8). The authors report a case of perineal testis in a 4 year old boy. The diagnosis was clinical and was confirmed by ultrasonography. Doppler studies visualised the testicular blood supply. The testis was surgically relocated in the scrotum.
睾丸的异位位置是由与正常下降至阴囊不同的迁移所定义的。这种异常是由于睾丸引带远端固定异常所致，从而导致睾丸位置异常。睾丸异位的五个主要部位是腹股沟浅环（最常见）、股管、耻骨上区域（阴茎根部）、对侧阴囊（罕见），最后是会阴区域，这也很罕见。作者报告了一例4岁男孩会阴睾丸的病例。诊断是临床诊断，并通过超声检查得以证实。多普勒研究显示了睾丸的血液供应。睾丸通过手术重新安置到阴囊中。
