Abstract

Aberrant epididymal tissue is uncommon and may be associated with an undescended testis. To the best of our knowledge, aberrant epididymal tissue has not been described in a testicular appendix. We report the case of a 7-year-old boy with left cryptorchidism who underwent a homolateral orchidopexy. At operation, the surgeon removed a pedunculated appendix testis containing an epididymal heterotopia. This Wolffian-derivative tissue was confirmed by the diffuse strong CD10 reactivity of the luminal border of the epithelial cells. Awareness of this aberrant tissue avoids misinterpretation as a transected functional reproductive structure.
