Double dermal sinus tracts of the cervical and thoracic regions: a case in a 3-year-old child and review of the literature

摘要

Introduction Dermal sinus tracts are rare congenital abnormalities characterized by an epithelium-lined tract that extends from the subcutaneous tissue to the underlying thecal sac or neural tube. These developmental anomalies can present asymptomatically with a cutaneous dimple or with devastating complications including recurrent episodes of meningitis, or neurological complications including paralysis. Dermal sinus tracts generally occur as single lesions, and the presentation of midline double dermal sinus tracts of the cervical and thoracic regions has not been previously described.
