Perineal-mound (PMD) and genital-fold defects cause anorectal malformations (ARM). These defects present differently in males and females, suggesting a need for separate classification in ARM. Further research into their embryological origins is warranted.

Area of Science:

  • Embryology
  • Pediatric Surgery
  • Medical Genetics

Background:

  • Perineal-mound (PMD) and genital-fold defects are primary causes of anorectal malformations (ARM).
  • These defects exhibit distinct presentations in females (typically low anomalies) and males (rarely, intermediate anomalies).

Purpose of the Study:

  • To discuss a common embryological explanation for the varied presentation of PMD and genital-fold defects in males and females.
  • To advocate for a separate classification of these anomalies within the broader category of ARM.

Main Methods:

  • Review of embryological principles related to anorectal development.
  • Clinical case series presentation of five male patients with PMD.

Main Results:

  • Five male patients with PMD were identified.
  • Three patients presented with imperforate anus, rectobulbar fistula, and perineal hypospadias.
  • Two patients presented with imperforate anus and rectoperineal fistula.

Conclusions:

  • PMD and genital-fold defects represent a distinct group of ARM with shared embryological origins but varied clinical manifestations.
  • A revised classification system for ARM may be beneficial to accommodate these specific defects.
  • Understanding the embryological basis is crucial for accurate diagnosis and management of these conditions.
