[Disseminated pigmented nevus syndrome].

Two patients carriers of a neuro-cutaneous syndrome showing scattered pigmentary nevus and neurologic disorders are exposed, who are added to three similar cases presented in a previous publication. Differences with other syndromes that show cafe-au-lait spots, like those of Recklinghausen and Albright, and also of other known publications, are remarked. Ultrastructural studies are contributed. The denomination of "disseminated pigmentary nevus syndrome" is proposed in comparison with the epidermal nevus syndrome.
