Pseudoverrucous papules: an aspect of incontinence in children.

Pseudoverrucous papules and nodules can be observed on skin surrounding urostomies and colostomies. These lesions appear to be uncommon, and sometimes can be misdiagnosed, even leading to surgical removal. We report the case of a 12-year-old boy whose lesions appeared in crops in an area subjected to urine leakage and spontaneously regressed in time. In this patient, anogenital warts had to be ruled out, but many skin diseases must be considered in the differential diagnosis of these misunderstood lesions. We stress the importance of a skin examination by a trained professional aware of these problems to avoid unnecessary investigations and treatments.
