[Infantile hemangiomas: differential diagnosis and associated anomalies].

Infantile hemangiomas are frequent benign vascular tumors that are often easily recognized. However, the diagnosis between infantile hemangiomas and other vascular tumors, whether benign or malignant, may be difficult. This chapter describes the different clinical presentations of hemangiomas and details the investigations that are needed to confirm the nature of the lesion and to diagnose the potentially associated anomalies. Knowledge on differential diagnosis enables clinicians to detect hemangiomas that can lead to complications and that necessitate a multidisciplinary approach.
