Aberrant epididymal tissue, a rare finding, was identified within a testicular appendix in a boy with undescended testis. This discovery highlights the importance of recognizing such anomalies to prevent misdiagnosis during surgery.

Area of Science:

  • Pediatric Surgery
  • Urology
  • Developmental Biology

Background:

  • Aberrant epididymal tissue is uncommon and often linked to cryptorchidism (undescended testis).
  • The presence of epididymal heterotopia within a testicular appendix has not been previously documented.
  • Testicular appendices are small structures that can be associated with congenital anomalies.

Observation:

  • A 7-year-old boy presented with left cryptorchidism and underwent an orchidopexy procedure.
  • During surgery, a pedunculated appendix testis was found to contain aberrant epididymal tissue (heterotopia).
  • Histological examination confirmed the tissue as Wolffian-derivative, showing strong CD10 reactivity.

Findings:

  • This case represents the first reported instance of epididymal heterotopia within a testicular appendix.

  • The aberrant tissue was identified as Wolffian-derivative, confirmed by CD10 immunohistochemistry.
  • The finding occurred in the context of treating cryptorchidism.

    • Implications:

    • Recognizing aberrant epididymal tissue in the appendix testis is crucial for accurate surgical interpretation.
    • This finding expands the spectrum of known ectopic tissues in the spermatic cord and associated structures.
    • Awareness prevents misinterpreting this heterotopia as a normal or damaged reproductive structure, aiding in correct surgical management.
