Primary adenocarcinoma of the seminal vesicle is an extremely rare tumor, and its prognosis has been known to be poor. Herein, we report an adenocarcinoma of the seminal vesicle. The patient was a 50-year-old man who complained of a two-month history of terminal hematuria and lower abdominal discomfort. A pelvic magnetic resonance imaging study. Indicated a seminal vesicle cyst with focal intraluminal growth. Right seminal vesiculectomy was performed. Grossly, the seminal vesicle revealed a markedly cystic change with focal, friable, intraluminal papillary growth. The intraluminal mass showed a noninvasive adenocarcinoma with a tubular and tubulopapillary pattern, accompanied by necrosis. Immunohistochemically, the tumor was positive for cytokeratin and carcinoembryonic antigen and negative for prostate specific antigen and prostatic acid phosphatase.
