A 7-day old female patient was referred by her neonatologist with a suspicion of a congenital anal fissure. During examination we found a perineal groove. She was born to a 26-year-old gravida 1 para 1 woman who did not take folic acid during her pregnancy. The patient was not noted to have any other associated anomalies during her exam.\nShe was followed up regularly for 2 years, and it was noted that the perineal groove spontaneously resolved.
A 15-day old female also with no other associated medical issues was referred by her neonatologist with an abnormality of the anogenital area. We diagnosed the patient with perineal grove in our clinic. She was born to a 38-year-old woman gravida 3 para 2. The mother did not take folic acid during her pregnancy.\nWe conducted follow-ups for 18 months, and it appeared that the groove underwent a spontaneous resolution.
