Prevalence of hypopigmented maculae and café-au-lait spots in idiopathic epileptic and healthy children.

The cutaneous lesions and findings related to the central nervous system are frequently seen concomitantly in many patients. Neurocutaneous syndromes are the most typical examples supporting this observation. The prevalences of hypopigmented maculae and café-au-lait spots were investigated in 210 idiopathic epileptic children between the ages of 2 and 17 years and 2754 healthy children between the ages of 5 and 15 years. In the group of epileptic children, hypopigmented maculae and café-au-lait spots were observed in 30 (14.3%) and 63 (30%) children, respectively. In the group of healthy children, the prevalence of hypopigmented maculae was 1.6% (44 children) and of café-au-lait spots was 2.83% (78 children). The difference between the two groups was very significant statistically (P < .0001).
