Immature renal tissue in inguinal canal.
A 3-year-old boy underwent an operation for a right undescended testis. A small, elastic, hard mass attached loosely to the spermatic cord was noted in the inguinal canal away from the testis and epididymis. Pathological examination of this mass revealed mesonephric remnant tissue.
