case_images: MRI of the leiomyoma of the prostate. MRI T2-weighted axial image (A) and fat-suppressed coronal image (B) shows a round mass in the prostate posterior lobe; fat-suppressed sagittal image (C,D) shows the clear surgical capsule of the tumor (arrow) and shows that normal prostatic glandular tissue and seminal vesicles were compressed anteriorly. The rectum was compressed posteriorly (red: leiomyoma of the prostate; green: prostate; pink: bladder and urethra; yellow: rectum; purple: seminal vesicles; light blue and arrow: surgical capsule of the tumour).

case_images: Magnetic resonance imaging (MRI) of the prostate revealed a round mass in the posterior lobe, 8.0 x 8.0 x 5.5 cm in size (Figure 1). A well-circumscribed capsule was observed around the tumor between the normal prostate, seminal vesicles, rectum and other organizational structures (Figure 1). T2-weighted images. This capsule was not the tumor's intrinsic capsule; therefore, we referred to it as the surgical capsule (Figure 1C arrow; Figure 1D light blue and arrow).
case_images: We were able to spare the prostate with the assistance of laparoscopy (A) and the prostate mass was completely resected (B).

case_images: Within the surgical capsular space and the external intrinsic capsule of the mass, the tumor was carefully isolated from the prostate tissue with an ultrasound knife, as hemostasis was maintained (Figure 2A). Eventually, the tumor was completely removed (Figure 2B), and the prostate and surrounding structures were spared.
case_images: The pathology of leiomyoma of the prostate. (A): Histopathological examination showed bland spindle cell proliferation (200x). (B,C): Immunohistochemical staining was positive for smooth muscle actin (SMA) (B) and Desmin (C).

case_images: Histopathological examination exhibited a bland spindle cell proliferation (Figure 3A). Immunohistochemical staining was positive for smooth muscle actin (SMA) (Figure 3B) and desmin (Figure 3C), and CD34 (vascular endothelium +, proliferating cells -) was negative for S-100, CD117, Dog-1, CK, and ALK.
