Phakomatoses

Phakomatoses (or "neurocutaneous syndromes") are diseases that are caused by neurological disorders, and primarily result in lesions on the skin and the retina.

This grouping is an artifact of an earlier time in medicine, before the distinct genetic basis of each of these diseases was understood.

Examples of Phakomatoses

 * neurofibromatosis
 * tuberous sclerosis
 * Sturge-Weber syndrome
 * von Hippel-Lindau disease
