Papillary adenocarcinoma of the rete testis with adjacent hyperplasia: a case report

Carolina Polanco, Cooley G. Pantazis, Rolando Prieto, Kenneth A Iczkowski


An 81-year-old man had a papillary adenocarcinoma infiltrating the rete testis with involvement of the epididymis and paratesticular soft tissue. The tumor was composed of papillary structures to focally solid areas with cells having abundant eosinophilic to clear cytoplasm, markedly atypical nuclei, and brisk mitotic activity. Invasive growth and extensive necrosis were present. Morphology, immunohistochemistry, and medical history support the diagnosis. Our case represents the second documented case with foci of adenomatous hyperplasia adjoining the tumor.
