Crossed testicular ectopia.

Crossed testicular ectopia/transverse testicular ectopia is an extremely rare anomaly, in which both gonads migrate toward the same hemiscrotum. About 100 cases of transverse testicular ectopia have been reported in published studies. We report a case of transverse testicular ectopia in an 8-year-old boy who presented with right inguinal hernia and nonpalpable left testis.
