Historically, there has been much debate on the nature of infantile hemangiomas as either congenital malformations or benign neoplasms. Some vascular lesions that are present at birth and evidence no proliferative growth are considered to be congenital malformations; other post-natal vascular tumors pursue aggressive and possibly lethal clinical courses. The ...
