Linear nevus sebaceus syndrome

Linear nevus sebaceous syndrome (LNSS) is characterized by the association of a large sebaceous nevus, usually appearing on the face or on the scalp, with a broad spectrum of abnormalities that may affect every organ system, including the central nervous system (brain neoplasms, hemimegalencephaly and lateral ventricle enlargement).
