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]
DDx:
- Adenomatous hyperplasia of the rete testis.
- Metastatic carcinoma involving the testis - usually prostate, kidney, or colon.[5]
- Sertoli cell tumour.
- Malignant mesothelioma.[1]
