title: Perianal pseudoverrucous papules and nodules after surgery for Hirschsprung disease.
abstract: We report two patients with Hirschsprung disease in whom severe diarrhea and a distinctive diaper dermatitis developed after delayed ileoanal anastomosis. The perianal papulonodular lesions cleared in months or years without specific treatment after resolution of the diarrhea. These perianal pseudoverrucous papules and nodules represent a peculiar form of primary irritant diaper dermatitis, distinct from Jacquet erosive diaper dermatitis and granuloma gluteale infantum.
