Mechanical Genital Maldevelopment Presenting as Pseudovaginal Perineoscrotal Hypospadias

Abstract

Pseudovaginal perineoscrotal hypospadias is the descriptive terminology of a phenotypic genital abnormality that may develop from multiple etiologic factors, such as defective virilization-masculinization owing to deficient androgenic synthesis, defective androgenic action or mechanical embryologic failure. The case presented herein typifies a mechanical abnormality that results in perineal hypospadias with the appearance of a vaginal introitus but with rectal mucosa incorporated in the urethral opening.
