Dermoscopy features of infantile perianal pyramidal protrusion

Abstract

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.

Infantile perianal pyramidal protrusion

“…Infantile perianal pyramidal protrusion is a benign perianal skin condition that occurs most commonly in girls younger than 5 years, but occasionally in boys and adults. [1][2][3] Anatomic weakness of the perineum or median raphe may contribute to its development. 2,4 Differences in perineal anatomy between the sexes may explain why infantile perianal pyramidal protrusion is more common in girls.…”

“… 2 , 4 Infantile perianal pyramidal protrusion typically presents as an asymptomatic, smooth, soft, pink-or flesh-coloured skin prominence ranging from 5 to 30 mm 2 in size, usually located anterior, but occasionally posterior to the anus. 1 , 2 Diagnosis is primarily clinical, and invasive investigations should usually be avoided. Differential diagnosis should consider skin tag, skin fold, condyloma acuminata, hemorrhoid, rectal prolapse and lesions from perianal abuse.…”

“…Differential diagnosis should consider skin tag, skin fold, condyloma acuminata, hemorrhoid, rectal prolapse and lesions from perianal abuse. 1 , 2 Conservative management is indicated as the lesion often resolves spontaneously within weeks to months. Treatment of constipation, if present, is beneficial.…”
