A case of teratoma occurling in an intraabdominal testicle in a 4mo. old infant was reported. The baby was admitted with left abdominal mass. He had been noticed of left undescended testicle from birth. Investigation after admission proved left abdominal tumor with calcification.Emergency laparotomy was performed at 4mo. 7d. of age. An intraabdominal 8×7×4.8cm tumor was removed. It was well capsulated, fed with left spermatic vessels and the left sper-matic cord was apparently going into the tumor. Histopathological examination of the removed tumor revealed mature teratoma containing bone, cartilage, fibrous tissue, fat, intestine, lymph-nodes, bronchus and nerve tissue. There was an atrophic tubular tissue of left testis attached to the tumor, suggesting that the tumor have occured from the left testis. This case may be the forth report of mature teratoma in undescended testes in children.
