title: Infantile perianal protrusion.
abstract: Infantile perianal protrusion is characterized by a skin fold located in the perianal area. It is a relatively recent reported condition and affects both infants and prepubertal children with a clear female predominance. Three types are recognized: constitutional/congenital, acquired, and associated with lichen sclerosus et atrophicus. We report eleven new cases, three of whom have the defect in locations that have been reported only once before. We would like to increase the awareness of this condition to avoid erroneous diagnostic and therapeutic procedures.
