Schwannoma of the Prostate: A Rare Case Report and Literature Review

Abstract

Introduction: We present a case of a schwannoma that originated in a prostate. It is very rare location presenting Schwannoma. Case report: A 64-year-old man presented with severe lower urinary tract symptoms. On digital rectal examination, there was a grade 3 enlarged prostate without nodules and tenderness. The transrectal ultrasonography revealed that prostate volume was 200 cc. Retroperitoneal transvesical prostatectomy was performed because of huge prostatic enlargement. Histopathology showed schwannoma of prostate. Conclusion: Owing to the lack of characteristic clinical manifestation, the final diagnosis of prostate schwannoma relies on postoperative pathological examination.

Prostatic schwannoma discovered after laparoscopic radical prostatectomy: A case report with literature review

“…Although uncommon, schwannoma should be considered when encountering a well‐defined, hypoechoic, or cystic lesion on prostatic MRI or ultrasound. Sporadic schwannomas in the genitourinary system, including the penis, spermatic cord, testis, or prostate, remain exceedingly rare 5 . The role of imaging in this case was pivotal for identifying and characterizing the prostatic mass.…”

“…Sporadic schwannomas in the genitourinary system, including the penis, spermatic cord, testis, or prostate, remain exceedingly rare. 5 The role of imaging in this case was pivotal for identifying and characterizing the prostatic mass. Imaging, specifically multiparametric mpMRI, played a crucial role in locating the mass, determining its size, and assessing its relationship with adjacent structures.…”

“…While they are commonly solitary masses found in soft tissues or spinal nerve roots, 1 schwannomas affecting the male genital system are infrequent and often managed surgically. Prostatic schwannomas, specifically, are extremely rare, with only a few cases documented in association with neurofibromatosis and even fewer occurring sporadically 2–8 . In this report, we present a unique case of prostatic schwannoma identified during the evaluation of a prostatic mass, ultimately confirmed through laparoscopic radical prostatectomy.…”

Periprostatic schwannoma mimicking metastatic lymphadenopathy in a case of multifocal prostate adenocarcinoma

“…The head, neck, and flexor surfaces of the upper and lower extremities are the sites most commonly affected [1]. Schwannomas of the prostate are a rare entity in patients with neurofibromatosis and are even rarer in patients without, such as in this case, with less than 10 documented incidents of prostatic or periprostatic schwannomas in PubMed-indexed literature to date [2][3][4][5][6].…”
