A full-term female newborn with a BW of 3540 g was born at 39 weeks of gestation via CS for breech presentation from a 35-year-old mother G1P1; Apgar score was 9 and 10 at 1st and 5th minute, respectively. On the ultrasound of the second trimester’s anatomy scan, mildly dilated lateral ventricles were detected, a finding that was confirmed by a cranial ultrasound on the 4th day of life. The first physical examination revealed a mildly erythematous sulcus extending from the posterior vaginal fourchette to the anterior anal orifice (). The diagnosis of perineal groove was confirmed by a Pediatric Surgeon. Since no other anorectal or genital anomalies were present and the baby passed stools normally, the perineal defect was simply observed and remained stable throughout the neonate’s 5-day hospitalization. Mild improvement in the epithelization of the area was already evident at discharge ().
A 2-month-old female patient presented with a perineal groove. The patient was already known to have a mild ventricular septal defect (VSD). She was born to a 40-year-old mother gravida 2 para 2. The mother did not take folic acid during her pregnancy.\nWe conducted follow-ups for 18 months. The VSD naturally closed at 9 months of age. The perineal groove also spontaneously resolved at 16 months of age.
