Xanthogranulomatous inflammation, as a type of chronic granulomatous inflammation, typically occurs in the gall bladder and kidneys. In this paper, we present a 56-year-old man with Xanthogranulomatous cystitis mimicking bladder malignancy. He was referred to our clinic with the chief complaint of a one-year history of urgency and frequency. CT scan showed a solid lesion in the bladder. The patient underwent complete transurethral resection of the bladder tumor. Microscopic histopathology revealed xanthogranulomatous cystitis. The patient received a course of antibiotic therapy. Follow-up Cystourethroscopy showed normal bladder.
