Pseudoverrucous papules and nodules (PPN) is an uncommon complication, mainly reported in the diaper area. It is thought to be a manifestation of chronic irritant contact dermatitis that develops as a result of prolonged exposure to liquid stool and/or urine. We describe a case of a peristomal PPN in a patient who had a urostomy after treatment of bladder carcinoma with radical cystectomy.
