Bladder Leiomyoma presenting as urinary retention: A case report

Leiomyoma of the bladder is a rare diagnosis and accounts for 0.43% of all bladder tumors. We herein present a case of a thirty-nine-year-old female diagnosed with bladder leiomyoma presenting with urinary retention. Workup of her urinary retention revealed a midline bladder neck mass. Transurethral resection of her tumor revealed pathology consistent with bladder leiomyoma. Surgical resection is generally the recommended management of this lesion to make a histopathological diagnosis despite low potential of malignant transformation. Although these tumors are benign, they can cause severe obstructive or irritative symptoms. Further research is needed to determine the pathophysiology of these tumors.
