Xanthogranulomatous cystitis masquerading as bladder tumor in a child.

Xanthogranulomatous cystitis affecting the urinary bladder is extremely rare, and only around thirty adult cases and two pediatric cases have been reported in the literature. The treatment is predominantly surgical as the lesion is mostly infiltrative and mimics malignancy. We report probably the third pediatric case, who presented with symptoms of urinary tract infection and urinary retention and was initially suspected as bladder tumor on imaging. The diagnosis was confirmed on histopathology, and the child responded well to aggressive antibiotic therapy alone.
