Abstract
Encephalocraniocutaneous lipomatosis (ECCL) is a sporadically occurring neurocutaneous disorder characterized by ocular anomalies, mainly choristomas; by skin lesions consisting of hairless fatty tissue nevi (nevus psiloliparus), focal dermal hypoplasia, alopecia, and periocular skin tags; and by CNS anomalies, including intracranial and spinal lipomas and often mental retardation and seizures. Here, we report on three boys with ECCL with typical abnormalities of the eyes, skin and brain and, in addition, coarctation of the aorta. All three children developed multiple cystic bone lesions, which progressively spread throughout the skeleton in Patient 1 and was shown histologically to be non-ossifying fibromas in Patient 2. We hypothesize that ECCL may be caused by mosaicism for a mutated gene involved in benign mesenchymal tumors and in vasculogenesis.
