Successful management with interferon alpha-2a after prednisone therapy failure in an infant with a giant cavernous hemangioma.

A giant cavernous hemangioma of the left arm with severe thrombocytopenia and consumptive coagulopathy was observed in a neonate. Initial treatment with prednisone, platelet transfusions, and clotting replacement failed to control the bleedings. The child was then treated with daily subcutaneous infusions of interferon alpha-2a. Coagulopathy rapidly improved and transfusions were drastically reduced. The hemangioma regressed progressively and disappeared after 4 months of treatment.
