ABSTRACT 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.

    ABSTRACT: Case Report Two female monochorionic-monoamniotic twins showed the same kind of infantile perineal protrusion (IPP) at birth. Lesions in both twins progressively healed until resolution in 6 weeks' time; none of the twins have manifested, till date, alvus disturbances. Discussion and Literature Review A literature review numbers approximately 100 reports of IPP. This condition has been classically classified into three categories: congenital/familiar (i.e., female sex, positive parental history of IPP), acquired (mainly due to constipation), and associated with lichen sclerosus et atrophicus. Conclusions and Final Remarks This case report describes, for the first time, the presence of IPP in monochorionic-monoamniotic twins, supporting the existence of hereditary/genetic factors in the developing of this condition.
