title: [A case of leiomyoma of the seminal vesicle].
abstract: Leiomyoma of the seminal vesicle is a rare tumor with only scattered reports in the literature. We report a case of leiomyoma of the seminal vesicle. A 65-year-old man presented with lower abdominal discomfort. Abdominal computed tomography scan and magnetic resonance imaging revealed a mass measuring 9.3 x 4.4 x 4.0 cm posterior to the seminal vesicle. The patient underwent ultrasound guided transrectal needle biopsy of the mass, and histological findings showed leiomyoma and no evidence of malignancy. To relieve persistent lower abdominal discomfort, the resection of the tumor was performed through a lower abdominal midline incision. The tumor was not adhered to surrounding tissue without the seminal vesicle and completely removed with a portion of the seminal vesicle. The mass weighing 115 g was histologically diagnosed as leiomyoma of the seminal vesicle with no evidence of malignancy. The symptom of lower abdominal discomfort promptly improved after the surgery, and the postoperative course was uneventful. The patient has been clinically free from the disease after three years of follow-up.
