Cystosarcoma Phyllodes of the Seminal Vesicle: A Case Report and Literature Review

Abstract

Cystosarcoma of the seminal vesicle is a very rare malignant tumor; in the literature only four cases are reported. We present a case of cystosarcoma phyllodes arising in the right seminal vesicle of a 49-year-old man without any urinary symptom but with persistent constipation. Ultrasound examination showed a mass at the right superior base of the prostate subsequently studied with CT and MRI. The patient underwent vesiculectomy; his postoperative course was uneventful. The patient is still well, without evidence of recurrent disease.

“…Because many cases of seminal vesicle cancer are advanced once diagnosed, the prognosis is generally poor. In previous reports, the overall survival of patients with advanced seminal vesicle cancer was ≤3 years in 95% of the cases 2,4 …”

“…In previous reports, the overall survival of patients with advanced seminal vesicle cancer was ≤3 years in 95% of the cases. 2,4 CT and MRI are useful for assessing the location and local extent of tumors. These imaging modalities are also useful in the diagnosis of congenital malformations (e.g., ectopic ureters or kidneys).…”

“…Diagnostic criteria for seminal vesicle malignancies include the absence of prostate-related tumors, adenocarcinoma focused primarily on the seminal vesicle, and papillary adenocarcinoma resembling the seminal vesicle mucosa. 4 Herein, we report a case of primary clear cell carcinoma of the seminal vesicle that did not meet these diagnostic criteria.…”
