A term, female infant with birth weight of 3.1 kg born to primigravida mother presented with abnormal-looking external genitalia. Mother was booked, immunized, had normal dating and anomaly scans with an uneventful antenatal period. Infant was completely asymptomatic, active, feeding well and had normal bowel and bladder function. Local examination revealed the presence of external midline mucosal connectivity between vaginal and anal orifice [Figure 1]. The defect was noted to extend into the perineum vertically downward in the midline from 6 o'clock position of the vaginal fourchette toward the anal rim. There were no other associated anomalies. Based on the morphological appearance, the lesion was diagnosed as Perineal groove (PG). Parents were reassured and the infant is currently on follow-up.

PG is an unusual congenital perineal malformation of unknown etiology characterized by a wet sulcus lined with nonkeratinized mucous membrane extending from the posterior vaginal fourchette to the anterior aspect of anal opening. This is a relatively unknown entity that is often missed or misdiagnosed as ambiguous genitalia, contact dermatitis, anal fissure, anorectal malformation, traumatic laceration, and sexual abuse., This condition is typically asymptomatic and self-limiting within 2 years of age. Complications such as local irritation, pain, local infection, urinary tract infection, and constipation have been reported. Persistence beyond 2 years of life or local complications often require surgical correction. Recognition of PG at birth is important for giving appropriate parental counselling and follow-up.
