Cystadenoma of the seminal vesicle

Abstract

Primary tumors of the seminal vesicle are extremely rare. Among them, there is a spectrum of tumors derived from both epithelium and stroma and so classified as epithelial-stromal tumors. Herein, we report a case of a cystadenoma in a 49-year-old asymptomatic man, detected in a routine ultrasonography for liver disease follow-up. The digital rectal examination detected a large mass anterior to rectum and posterior to bladder. Computed tomography scan and magnetic resonance imaging showed a normal prostate and a 9.0 cm cystic tumor, replacing the left seminal vesicle. The gross appearance and microscopic aspect was compatible with cystadenoma of seminal vesicle. Patient's postoperative recovery was uneventful. He is currently alive, 3 years after the diagnosis, with no signs of recurrence.

Schwannoma, a rare tumor of the seminal vesicle

“…All cases of schwannoma of the seminal vesicle that have been reported underwent transrectal ultrasound guided biopsy and surgical excision thereafter [2, 4, 7, 8]. Regardless, biopsies may be inconclusive and exploratory laparotomy/laparoscopy is usually needed [1]. In the present case, the small, solid non-invasive tumor documented in the TRUS and MRI, and the data available led us to refrain from performing a biopsy and to follow a conservative surgical approach.…”

Cystadenoma in a seminal vesicle is cured by laparoscopic ablation

“…1 In some cases, cystadenoma of the seminal vesicle was an incidental finding of an asymptomatic mass. 2,3 The majority of patients present with symptoms of urinary outflow obstruction, haematuria or haematospermia. [4][5][6] The wide variety of presenting features might result from variations in the size and location of the retrovesical mass.…”

“…2,3 Open surgery includes transperineal, transvesical, paravesical, retrovesical and transcoccygeal approaches. In one case, radical cystoprostatectomy, low anterior resection of the rectum and orthotopic neobladder reconstruction were performed.…”

Rare primary seminal vesicle cystadenoma: computed tomography and magnetic resonance imaging findings

“…Benign primary tumors including cystadenomas are even rarer than malignant neoplasms 12. Herein, we report a 71-year-old man with cystadenoma of the seminal vesicle.…”

“…When imaging findings are nonspecific, the US or CT-guided biopsy is crucial. Regardless, biopsies may be inconclusive, and exploratory laparotomy or laparoscopy is usually needed 14…”
