Primary squamous cell carcinoma of the seminal vesicle: A case report and review of the literature.

RATIONALE

Primary squamous cell carcinoma (SCC) of the seminal vesicle is extremely rare, and the clinical characteristics of this kind of malignancy are still unclear.

PATIENT CONCERNS

A 62-year-old male patient presented with complaints of sensation of rectal tenesmus and dysuria.

DIAGNOSIS

Ultrasonography suggested a hypoechoic mass behind the bladder, meanwhile, computerized tomography (CT) and magnetic resonance imaging (MRI) revealed a 40 mm × 45 mm × 48 mm mixed solid/cystic tumorous lesion in the right seminal vesicle. Postoperative histology confirmed the diagnosis of primary SCC in the seminal vesicle.

INTERVENTION

The mass was surgically excised with a laparoscopic approach. Postoperatively, 6 cycles of chemotherapy and 50 Gy of external beam radiation were concurrently performed on this patient.

OUTCOMES

No local recurrence or distant metastasis was detected within 2 years after the surgery.

LESSONS

Primary SCC of the seminal vesicle is a rare neoplasm with a poor prognosis. Clinically, it is crucial to establish early precise diagnosis and apply multimodality treatment.
