[Acute hematuria as first manifestation of bladder urothelioma in a 17-year-old adolescent].

OBJECTIVE: To report a case of urothelial tumor of the bladder in a 17-year-old patient that required emergency surgical treatment due to acute hematuria. METHODS: The clinical history, anatomopathological and immunohistochemical findings are described. RESULTS: A 17-year-old patient with no remarkable clinical history, consulted at the emergency services for gross hematuria of sudden onset that caused anemia and was refractory to conservative management. Patient evaluation disclosed a bladder lesion that required immediate resection via the transurethral approach to control bleeding. The pathological analysis demonstrated a grade I, Jewett stage 0, pTaN0M0 transitional cell carcinoma of the bladder. CONCLUSIONS: Urothelial tumors of the bladder are uncommon in patients less than 40 years old. The case described herein is uncommon because of the patient's age and the form of presentation of the tumor, which required emergency surgical treatment. Follow-up and subsequent therapy should be based on the pathological characteristics of the tumor rather the age of the patient.
