“…Abdollahi's study found that PSA has little clinical utility in the diagnosis of leiomyoma ( 24 ). When prostate leiomyoma is combined with BPH or prostate cancer, the PSA level becomes raised ( 12 , 20 ). Biopsy is then useful in assisting with a correct diagnosis.…”

Leiomyoma of the prostate: A case report and systematic review

et al. 2022

PurposeIt is rare to find a large leiomyoma in the prostate, especially in that of a young man. This case report and systematic review provides additional information on the diagnosis, distinguishing features of imaging examinations, and treatment options.Patients and MethodsWe report on the case of a thirty-year-old man with a large leiomyoma of the prostate. MRI of the prostate revealed a round mass in the posterior lobe, 8.0 × 8.0 × 5.5 cm in size. With the assistance of laparoscopy, we resected the prostate mass completely and spared this organ. A systematic review was conducted utilizing the Preferred Reporting Items for Systematic Reviews (PRISMA) including English language published reports, from 1970 to December 2021.ResultsUrinary and erectile functioning was preserved postoperatively. After a year of follow-up, no evidence of recurrence emerged. A total of 21 studies were included for analysis.ConclusionsA medical history of no, or few, lower urinary tract symptoms; the characteristics of a benign tumor in imaging examinations; and negative tumor markers should be included in any differential diagnosis of leiomyoma of the prostrate. A prostate biopsy should be performed before the preparative radical prostatectomy and choose nonsurgical treatment to confirm the diagnosis. Nowadays, minimally invasive surgery is the preferred effective option for this disease. It is a rare recurrence after its removal by means of surgery.

“…To the best of our knowledge, ultra-high b-value DWI and ADC features of the prostatic leiomyoma have not been reported in the literature till date. Only Mussi et al have reported 3 cases with low and intermediate b-values DWI and ADC maps (b values = 50, 400 and 800) [ 15 ]. In our case report, typical features of the prostatic leiomyoma were slightly homogeneous hyperintense signal compared to the muscle on DWI and a higher ADC value as compared to the prostate cancer, which altogether reflecting pathological characteristics of abundant muscle or fibrous tissue component.…”

Ultra-high b-value diffusion-weighted imaging features of the prostatic leiomyoma-case report

et al. 2017

BackgroundLeiomyoma of the prostate is a rare benign tumor arising from smooth muscle fibers. Most cases are incidental findings observed during pathological examinations after resection of the prostate. To the best of our knowledge, only few studies have reported the conventional magnetic resonance imaging (MRI) findings of such tumors; however, no reports have described the ultra-high b-value diffusion-weighted imaging (DWI) and apparent diffusion coefficient (ADC) findings of prostatic leiomyomas.Case presentationWe report MR imaging characteristics and surgical pathologic findings of a case of prostatic leiomyoma treated by robot-assisted transperitoneal laparoscopic approach. Typical MR features showed a homogeneous lesion with slightly hypointense signal compared to the skeletal muscle on T2-weighted images, and isointense signal relative to the muscle on T1-weighted images with fat suppression, which collectively demonstrate apparent homogeneous enhancement with a non-enhanced envelope. A slightly hyperintense signal compared to the skeletal muscle was observed on ultra-high b-value DWI, and higher ADC values were observed as compared to the prostate cancer.ConclusionsProstatic leiomyoma is a benign tumor. This case indicates that MRI features of prostatic leiomyoma are helpful for the differential diagnosis of prostate cancer.

Leiomyomlar benign mezenşimal düz kas tümörleridir. Prostatın pür leiomyomları nadirdir. Burada kliniğe infravezikal obstrüksiyon semptomları ile başvuran 77 yaşında olgu sunulmuştur. Rektal tuşe ve ultrasonografik inceleme ile prostatda büyüme belirlendi. Açık prostatektomi uygulandı. Makroskopik incelemede prostat 172 gr ağırlıktaydı ve kesit yüzeyinde solid nodüler lezyon görüldü. Mikroskopik incelemede lezyon nükleer atipi, nekroz ve mitotik aktivite içermeyen iysi hücre proliferasyonundan oluşuyordu. Radyolojik yöntemler bu ve benzer lezyonların biyolojik doğasını belirlemek için yeterli değildir. Bu açıdan histopatolojik inceleme malignitelerin ekarte edilmesi için önemlidir. Açık prostatektominin uygulanması hem tanısal, hem de tedavi açısından efektifdir.
