“…Several case reports from across the globe have identified that this defect can affect any ethnicity and largely prevalent in female infants. [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] Congenital perineal groove malformation appears as an exposed wet nonepithelized erythematous mucous membrane sulcus that extends vertically downward from the posterior portion of the vaginal fourchette to the anterior rim of anus. 2,3,11 There are two forms of congenital perineal groove 13,15 : the complete form with the lesion extends from posterior vaginal fourchette to anterior rim of anus, and the incomplete form.…”

Perineal groove is a rare benign congenital anomaly with lesion that resembles perforation of mid-perineum or perineal raphe area. Most reported cases of congenital perineal groove presented as an isolated defect in term or early-term singleton female infants. Thus far, there is no reported case of this anomaly in monozygotic twins. Embryo pathogenesis of this female predominance congenital defect remains controversial. Many clinicians are unfamiliar with this congenital anomaly. This congenital defect tends to get self-resolved at around 2 year of age. Nevertheless, the exposed nonepithelized mucous membrane can carry risk of local infection or irritation with the possibility of requiring early surgical correction. The defect can be infrequently associated with other ano-urogenital malformations that required immediate surgical intervention. Most isolated cases tend to be asymptomatic and self-healed with expectant management. Surgical correction may be considered if not healed after 2 years of age. Early diagnosis at birth is important to avoid misdiagnoses at later age for trauma, dermatitis, sexual abuse, and risk of unnecessary aggressive intervention. Early parental counseling for providing good hygiene and close follow-up is important to prevent infection or inflammation. Presentation of this anomaly in both monozygotic twins may support the hypothesis of potential disruption during embryo morphogenesis stages.

“…While comorbid conditions are rare, there have been reported cases in which perineal grooves were associated with other urologic or genital anomalies such as urinary tract abnormalities, anorectal malformations, ectopic anus, vestibular fistula, and rectal prolapse. 5 , 13 , 14 There have been reports of hypospadias and bifid scrotum; however, these are exceedingly uncommon as perineal grooves are rare in males. 15 Complications of perineal grooves are also uncommon but can include constipation, recurrent skin infections, mucus drainage, and urinary tract infections.…”

“…A recent review of the literature from 2018 found only 36 cases to date of perineal grooves, one of whom was in a male. 13 , 14 An additional case series from Korea examined 26 cases of pediatric patients diagnosed with perineal grooves from 2012 to 2018 and reported only one male with associated findings. 18 Aside from the perineal groove, these infants tended to be healthy overall with generally no symptoms related to the anomaly.…”

Twin girls born at term were noted to have hypertrophic and erythematous mucosal sulci extending from the posterior vaginal fourchette to the anterior ridge of the anus on their newborn exams. Pregnancy was complicated by gestational hypertension and dichorionic diamniotic twin pregnancy. No known traumas were sustained during delivery to either twin. Dermatology and obstetrics/gynecology were consulted who confirmed the diagnosis of perineal groove. Primary care follow-up was recommended, with referral to pediatric gynecology if the lesions did not epithelize by 2 years of age. Our case of perineal grooves is unique in that, to our knowledge, it is the first reported case of perineal grooves identified in both twins. Clinicians in the newborn nursery and primary care settings should perform routine genitourinary and anal examinations on all newborns to identify this benign lesion, which may limit misdiagnosis, inappropriate treatments, and invasive workups in the future.

“…Improvement of perineal grooves most often occurs over time, with improvement noted at 2 months [4], 1 year [14], 14 months [19], and 17 months [5] of life. The majority close spontaneously by 2 years of age [22]. Surgical intervention is usually not necessary, although indications include infection [8,23], failure to spontaneously close [8], and cosmetic concern [16][17][18]23].…”
