Leiomyoma of the urinary bladder with bladder stone.

Leiomyoma of the urinary bladder is a rare benign mesenchymal tumour. We describe here a case of leiomyoma of the urinary bladder in a 65-year-old gentleman who presented with haematuria, passage of clots and combined obstructive and irritative urinary symptoms. The investigations revealed a vesical calculus and a mass on the left lateral wall of the urinary bladder. Cystolitholapaxy and transurethral resection of the tumour was performed. Histopathological report of the resected tumour revealed a leiomyoma of the urinary bladder. So far, a leiomyoma of the urinary bladder and a concomitant vesical calculus have not been described in literature.
