[Photosensitivity in children with malign tumors (author's transl)]

Photosensitivity (photoconvulsive reaction = PCR) has to be regarded as a genetically determined EEG-symptom, which is seen with markedly age dependent in up to 15% of healthy individuals. Correlations with epileptic and nonepileptic diseases (migraine, anorexia nervosa, psychovegetativ instability) are known. 157 children with malign tumors (Tab 1) were investigated. Children with Wilms' tumors showed significant more PCR than all other children with malign tumors (Tab. 2, 3). That finding may corroborate the hypothesis, that Wilms' tumor may be the most important clinical symptom of syndroms with congenital malformations (aniridy, hamartom, hemihypertrophy).
