Abstract:
We examined four patients who had a combination of extensive nevus flammeus, significant oculocutaneous pigmentation, and severe neurologic alterations. All cases were sporadic. The vascular and neurologic alterations were clinically similar to those observed in the Sturge-Weber syndrome. The capillary vessels are ultrastructurally different in phacomatosis pigmentovascularis from those of a nevus flammeus in the Sturge-Weber syndrome; however, melanocytes of normal aspect were present in the middle and deep dermis. The characteristic oculocutaneous pigmentation probably represented a noncoincidental association. The term phacomatosis pigmentovascularis seems appropriate for this apparently new neurocutaneous syndrome.
