Eosinophilic Cystitis : A Rare Cause of Hematuria in Children

Abstract EN

A 7-year-old boy presented with a history of acute onset of hematuria, dysuria, and suprapubic pain.

Urine routine and microscopy showed 40–45 red cells/high power field.

Urine culture was sterile.

Radiological investigations showed a focal mucosal lesion with bladder wall thickening.

Biopsy of the lesion revealed an edematous mucosa with florid infiltration by eosinophils into the muscularis propria with focal areas of myonecrosis.

He was diagnosed as a case of eosinophilic cystitis.

The patient received 6 weeks of tapered prednisone therapy.

He was asymptomatic on followup.
