Sarcoma is a rare malignant lesion in the urinary bladder and remains unknown of its natural history. We report a case of primary bladder sarcoma with long-term follow-up. A 35-year-old man suddenly presented with severely gross hematuria. Computer tomography was showed solitary lesion at the anterior wall of the urinary bladder without distant metastases. Transurethral resection of the bladder tumor (TURBT) was performed. Pathologic findings demonstrated sarcoma in the urinary bladder without remnant lesions. Immunohistochemical staining using conventional antibodies was not classified as the origin of this sarcoma. There have been no signs of recurrence during twenty years' follow-up after the treatment.
