title: Leiomyosarcoma, a nonurothelial bladder tumor: a rare entity with therapeutic diversity.
abstract: A 22-year-old young woman presented with dysuria and lower urinary tract symptoms that had persisted for 6 months. She was diagnosed with a tumor near the bladder neck. Transurethral resection was done under anaesthesia. The histopathological examination with immunohistochemical staining showed the tumor to be a low-grade leiomyosarcoma. Adjuvant chemoradiation was given, and the patient has been doing well for 12 months of follow-up. Nonurothelial tumors of the bladder are rare and consensus is lacking regarding their definitive treatment. Furthermore, little is known about the natural history and prognosis of this type of bladder sarcoma. We present a minimally invasive treatment for this relatively rare tumor in which bladder preservation was achieved with no evidence of local or distant recurrences during the follow-up to date.
