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.
足月出生的双胞胎女孩在新生儿检查时被发现有肥厚、红斑样的黏膜沟，从阴道后穹隆延伸至肛门前缘。孕期并发妊娠期高血压及双绒毛膜双羊膜囊双胎妊娠。分娩过程中两个胎儿均未遭受已知创伤。咨询皮肤科及妇产科后确诊为会阴沟。建议进行初级保健随访，若病变在2岁时仍未上皮化，则转诊至小儿妇科。据我们所知，我们的会阴沟病例很独特，是首例在双胞胎中均发现会阴沟的报道病例。新生儿重症监护室及初级保健机构的临床医生应对所有新生儿进行常规泌尿生殖系统及肛门检查，以识别这一良性病变，这可能会减少未来的误诊、不恰当治疗及侵入性检查。
