Renal Pelvic Cholesteatoma: An Uncommon Finding in Children.

Renal cholesteatoma or keratinizing desquamative squamous metaplasia is infrequent in adults and rare in children. We report a case of renal cholesteatoma in a 4-year-old male child who was referred to us as a case of multiple renal calculi with hydronephrosis. We also discuss his management with a review of relevant literature.
