[Phakomatosis pigmento-vascularis. Report of 2 cases associated with angiodysplasia].
Phakomatosis pigmentovascularis is an uncommon disease, with a peculiar association of capillary hemangioma and pigmented lesions. Four entities have to date been described (I to IV), with localized (a) or systematical (b) involvement. In this latter subtype, the cutaneous lesions are associated with visceral (eye, central nervous system) and bony abnormalities. We describe two additional cases of phakomatosis pigmentovascularis type II (b) associated with a Klippel-Trenaunay syndrome. These reports emphasize the frequent occurrence of angiodysplasia of the Klippel-Trenaunay or Sturge-Weber-Krabbe type in the systemic subtype, especially II (b). Accordingly, complete investigations are warranted in all cases, with special attention for bones and some internal organs like eye and central nervous system. Pathophysiological hypothesis for phakomatosis pigmentovascularis are discussed.
