Abstract
- Inflammatory pseudotumor of urinary bladder is a rare benign entity that clinically and radiologically simulates a malignant tumor. This benign lesion can easily be mistaken for sarcoma, and only careful pathologic examination can provide a definite diagnosis. It is important to recognize this lesion as benign to avoid the potentially serious consequences of misdiagnosis. A 53-year-old man presented with a history of micturition pain and urinary frequency despite of symptomatic treatment with antibiotics for 2 weeks. Cystoscopic examination, ultrasonography and of revealed a well defined mass with central necrosis. The mass was located at the left lateral wall of the bladder, and it was 3x3 cm sized round shape. We suspected benign tumor by above diagnostic modalities and we confirmed inflammatory pseudotumor by frozen section of mass, followed by partial cystectomy was performed. Awareness of this unusual lesion is important to prevent unnecessary surgical procedure. We report a case of inflammatory pseudotumor of the urinary bladder and reviewed 21 cases of this disease including our case.
