Tratamento de hemangioma gigante com interferon alfa: Relato de dois casos

Abstract

The aim of this study is to describe the treatment using interferon-alpha of giant hemangiomas in children. The authors report two cases of children presenting with giant hemangiomas treated using interferon-alpha and analyze the results. IBS, 3 years-old, has been followed up in Famema Hemathology Service since she was 1 year-old with a tumor on the face and persistent bleeding. After clinical and radiologic evaluations and suggested the diagnosis of giant hemangioma, she started treatment with interferon-alpha. A great clinical improvement was observed a reducing of the number of episodes of bleedings and a decrease in of the tumor size. CNP, 12 years-old, came to this service in the last year presenting with a small painful tumor on the left knee. She had already tried a treatment with Prednisone with no improvement. Treatment with interferon-alpha was initiated with a significant decrease in its size. The use of interferon-alpha should be considered in the treatment of giant hemangioma due to its favorable results related to a reduction in the tumor size and the episodes of bleeding.
