Open Partial Cystectomy of Intramural Bladder Leiomyoma With Unfavorable Position: A Rare Case Report

Benign tumor of the bladder (Leiomyoma) is a rare condition representing less than 0.5% of all bladder tumors. A 50-year-old female presented with asymptomatic hematuria for three months. Abdomen and pelvic magnetic resonance imaging (MRI) revealed a large intraluminal mass originating from the submucosal layer of the left anterolateral wall of the urinary bladder. An ultrasound-guided biopsy was performed, and a histopathological examination showed a spindle cell tumor. Cystoscopy revealed a massive indentation in the left posterolateral site of the urinary bladder extending to the bladder's dome. The patient underwent open partial cystectomy. At the follow-up, the patient was evaluated, and there was no hematuria or other complaints. Open partial cystectomy is the treatment of choice in an intramural tumor with an unfavorable position and difficulty in recognition.
