Large multifocal cutaneous hemangioma along lines of Blaschko with cardiac failure treated with propranolol.

Hemangiomas are classified as focal or segmental according to the morphology and distribution of lesions. Congestive cardiac failure is frequently encountered in diffuse hepatic hemangiomas due to high-volume shunting and rarely in hemangiomas confined to the skin. We report here the case of a large multifocal hemangioma along the lines of Blaschko with high-output cardiac failure, with improvement in cutaneous and hemodynamic symptoms after propranolol therapy. Presentation along the lines of Blaschko raises the possibility of hemangiomas arising as a result of mosaicism.
