This is aplasia cutis congenita overlying deeper embryologic malformations. [27, 28, 29, 30] Examples include meningomyelocele, porencephaly, leptomeningeal angiomatosis, cranial stenosis, spinal dysraphism, gastroschisis, and omphalocele. A hair collar is often present in the scalp lesions overlying neural tube defects. Intracranial arteriovenous malformations and fistulas have also been reported in association with scalp aplasia cutis congenita in rare cases. [31] The inheritance pattern in this group varies with the associated underlying condition.
