Adenocarcinoma of the rete testis, also rete testis adenocarcinoma, is a very rare malignant tumour of the testis.

General

  • Extremely rare[1] - a few dozen cases in the world literature.
  • Typically older men (>60 years old), but reported in younger men with undescended testis.[1]
  • Possible association of diethylstilbestrol.[2]
  • Prognosis poor[3] - 3-year and 5-year disease-free survival approximately 50% and 15% respectively.[4]

Gross

  • Lesion of the testicular hilum.[1]

Microscopic

Features:

  • Adenocarcinoma:
    • Atypical columnar or cuboidal cells, often with cigar-shaped nuclei.
    • Tubular or papillary architecture.[2]
  • Transistion to normal appearing rete testis.[1]
