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 6-month-old female was referred to the clinic by her pediatrician due to abnormal findings in the genitalia.\nA perineal groove was found during examination. She was born to a 31-year-old woman gravida 3 para 2 who had not taken folic acid during her pregnancy.\nThe patient had been observed for 6 months. The perineal groove has not yet been resolved; the patient remains under observation, though there is no plan for surgery at this point.
