title: Phacomatosis pigmentovascularis with a selective IgA deficiency.
abstract: We report a 1-year-old boy with an extensive cutaneous vascular malformation, oculocutaneous pigmentation, and severe neurologic abnormalities from birth, as well as a selective IgA deficiency. Ultrastructural study demonstrated prominent endothelial cells in the luminal of the blood vessels. The diagnosis of phacomatosis pigmentovascularis type IIb seemed appropriate for this patient.
