Infantile perianal pyramidal protrusion treated by topical steroid application

Dermoscopy features of infantile perianal pyramidal protrusion

Infantile perianal pyramidal protrusion (IPPP) is a benign condition generally noted in childhood but may persist for several years. Dermoscopy may help to distinguish it from other conditions, particularly genital warts. We report six cases of IPPP and describe the dermoscopic features that will distinguish these lesions from verrucae.

A Case of Infantile Perianal Pyramidal Protrusion Masquerading As Imperforate Anus at Birth

Infantile perianal pyramidal protrusion (IPPP) is an uncommon and underreported benign cutaneous lesion characterized by a protrusion from the anal orifice. It is also believed to be often mistaken for other conditions. The unawareness of this lesion may be responsible for underreporting and an excessive concern both in providers and in parents. Timely diagnosis and reassurance need to be emphasized in the provider community. We report an interesting case of IPPP on the first day of life, which was erroneously diagnosed as imperforate anus at her delivery.

Infantile perianal pyramidal protrusion: a report of 8 new cases and a review of the literature

Infantile perianal pyramidal protrusion (IPPP) is characterized by a protrusion located most often anterior to the anus. Three types of IPPPs are recognized: (a) constitutional, (b) acquired (mainly due to constipation), and (c) IPPPs due to lichen sclerosus et atrophicus. The aim of this study was to make a brief review on IPPPs from articles retrieved from PubMed, and to present our experience in this field. We conclude that awareness of pediatric surgeons and pediatricians of the condition is essential for the correct diagnosis of IPPP, and could help to avoid erroneous investigation of other lesions in this area.
