title: Inflammatory myofibroblastic tumor of the urinary bladder in a patient with the left renal cell carcinoma: A case report.
abstract: This case report describes an inflammatory tumor of the urinary bladder along with left renal cell carcinoma which occurred in a 73-year-old male with a narrowed orificium urethrae internum and severe hyperplasia of the prostate gland. A biopsy was not obtained prior to surgery. An inflammatory myofibroblastic tumor (IMT) of the urinary bladder is a rare benign lesion, particularly in the elderly. To the best of our knowledge, there are no studies concerning IMTs of the urinary bladder in patients with unilateral renal cell carcinoma. A bladder lesion due to an IMT may be easily misdiagnosed as metastasis from left renal cell carcinoma due to the hypervascularity of the tumor. In this case, radical surgery of the cancer of the left kidney was performed by laparoscopy. Subsequently, after three weeks and according to the examination of the intraoperative frozen-sections, a partial cystectomy was performed. Thus, radical resection of the bladder and the associated complications were avoided.
