title: Primary adenocarcinoma of the seminal vesicle.
abstract: A rare case of primary adenocarcinoma of the seminal vesicle is examined in an 87-year-old Japanese man. Neoplastic cells, especially poorly differentiated cells, showed a positive reaction with periodic acid-Schiff reagent and anti-carcinoembryonic antigen. Neoplastic cells invaded the bladder wall but not the prostate. No other primary tumor was demonstrated.
