Pyogenic Granuloma: Possible Cause for Macroscopic Hematuria in Children.

Pyogenic granuloma (PG) is a benign, vascular tumor that is rarely reported in the urinary tract of pediatric population. Herein we present a case of a child followed up for recurrent painless macroscopic hematuria. We performed ureteroscopy, and a whitish lesion was discovered in the upper calyx of the right kidney. The lesion resected endoscopically, and microscopic examination of the lesion was consistent with PG. It is important for pediatricians and urologists to properly recognize PG as a possible source of hematuria in the pediatric population.
