Abstract

Torsion of the testicular appendix is a common cause of acute scrotum, and occurs during the prepubertal years. However, despite its high incidence, appendix torsion in undescended testis has rarely been reported. Herein, a rare case of torsion of the testicular appendix in an undescended testis is reported in a 9-year-old boy
