Abstract

Background/aim: Solitary fibrous tumors (SFTs) are ubiquitous mesenchymal neoplasms that have an unpredictable biological behavior. Histological criteria for this type of malignancy are uncertain. Clinical characteristics, diagnostic and treatment options of SFTs originating in the seminal vesicle are presented in this review article.

Materials and methods: A systematic review including the following databases: Scopus, Embase and Medline from 1960 until the end of March 2021 was performed according to the Preferred Reporting Items for Systematic Reviews (PRISMA) guidelines.

Results: We found seven patients affected with SFTs of seminal vesicle, in which we added our own case, making a total of 8 patients. Mean age at presentation was 55±7 years. Mean size of the SFTs was 9±2 cm and the right seminal vesicle was preferentially involved. The majority of patients were symptomatic and presenting symptoms were hematuria, dysuria, hematospermia, urinary increased frequency and urgency. Abdominal ultrasonography, computed tomography (CT) scan, and magnetic resonance (MRI) were the diagnostic tools. Trans-rectal ultrasound-guided core biopsy was also used. Seven (87%) patients had open surgery. Adjuvant radiotherapy after R0 resection was used in 1 patient.

Conclusion: The treatment of SFTs located in the seminal vesicle necessitates a radical surgical resection to obtain acceptable results in terms of local recurrence and distant metastases.

Keywords: Solitary fibrous tumors; hemangiopericytoma; review; seminal vesicle tumor.
