A case of myxofibrosarcoma of the bladder

Abstract A 43-year-old woman presented to our hospital with the chief complaints of gross hematuria and dysuria. Cystoscopy and magnetic resonance imaging showed a tumor on the dome of the bladder and large blood clots. Computed tomography demonstrated no findings of distant metastasis. Following transurethral resection of the tumor, the tumor was histologically diagnosed as myxofibrosarcoma with muscular invasion, and partial cystectomy was performed in September 2009. There has been no evidence of recurrence or metastasis for 24 months postoperatively. In addition, the Japanese literature on myxofibrosarcoma of the bladder was reviewed and discussed.
