Leiomyoma of the urinary bladder.

Leiomyoma of urinary bladder is a rare tumour with an incidence of < 0.5% of all the bladder tumours. We report a case of leiomyoma of bladder after taking written and informed consent from a 38 years old female, after obtaining the permission of the institutional review board (IRB). She presented in November 2015, with symptoms of obstructive lower urinary tract for 1 year followed by acute urinary retention. Physical examination was unremarkable. Ultrasound showed well circumscribed polypoidal growth in the bladder with mild hydronephrosis on the left side. CT scan abdomen and pelvis with contrast was done, which revealed well circumscribed, rounded soft tissue lesion of 4.4 x 4.5 cm at the posterior inferior surface of the bladder near the bladder neck. Initially TURBT was done but after 6 months patient again went into urinary retention so local excision of the tumour was done. Histopathology confirmed the diagnosis of leiomyoma of the bladder. The diagnosis and management of leiomyoma of the bladder is presented along with review the literature.
