RESUMO
During fatal development, the testes grow in the abdomen and descend into the scrotal sac. It can be stopped at any point along its path (cryptorchidism) or migrate to an atypical side (ectopic testis). A 47-year-old man from Somalia's lower Shabelle region was presented to the urology OPD, He had a history of non-tender abdominal mass for the previous four months, An examination revealed a mass in his abdomen that was firm, non-tender, and immobile, an abdominal ultrasound and a contrast enhanced CT abdomen showed a 15-cm heterogeneous bean-shaped mass above the bladder. After patient counseling and informed written consent, a laparotomy was done to remove the tumor. A seminoma of the undescended testis was identified during a histological examination. An intra-abdominal mass with empty scrotum should raise concerns about an intra-abdominal testicular tumor. To prevent/early discover these types of tumors, cryptorchidism should be treated at a young age, particularly before to the first year.
