Abstract
Testicular tumour in an intra-abdominal undescended testis is a rare finding. We report a case of mature teratoma in an intra-abdominal testis of a 4-year-old boy. He presented with nonpalpable testis on the right side. Abdominal ultrasound was normal. Diagnostic laparoscopy revealed a large tumour arising from an intra-abdominal right testis, and histologic analysis identified a mature teratoma. The tumour was completely removed laparoscopically, and there was no recurrence at follow-up 1 year later.
