Abdominal wall ectopic testis mimicking spigelian hernia.

We encountered a patient with a swelling in the left lateral infraumbilical region and a left undescended testis. The appearance of the swelling was suggestive of a spigelian hernia. At operation, the swelling was actually an abdominal ectopic testis with associated inguinal hernia. This unusual finding led us to report this occurrence and present a brief review of the relevant literature.
