title: Perineal groove and perineal canal.
abstract: Perineal groove is a rare congenital wet sulcus extending from the fourchette to the anus. With awareness of the lesion, surgery can be avoided. Perineal canal is a congenital anorectovestibular fistula coexistent with normal anus. Recently, it has become evident that these lesions are relatively common and clinically important variants of anorectal anomalies. We now report one patient each with these anomalies and briefly review the surgical problems.
