Linear nevus sebaceous syndrome.

The linear nevus sebaceous syndrome is a rare disorder first described in 1962 in two cases by Feuerstein and Mims. As originally described, it consisted of the triad of the characteristic midline facial linear nevus sebaceous of Jadassohn, seizures, and mental retardation. The authors have followed a patient with this syndrome from birth to age 8 and although he does demonstrate several neurologic and ocular abnormalities, he enjoys normal intelligence and has never suffered seizures. The features of this syndrome and several new ocular findings demonstrated in this case are described. Based on our long-term follow-up of this patient and our review of the reported cases to date, the authors suggest that the triad for this disorder should be changed to include the midline facial linear nevus sebaceous of Jadassohn, neurologic abnormalities which may, but not necessarily, include seizures and mental retardation, and ophthalmologic abnormalities.
