[Vascular anomalies of the children's hand]

Vascular anomalies are common on the hand of children. There are two types of vascular anomalies: the vascular tumours and the vascular malformations. The most frequent vascular tumour is infantile haemangioma. The vascular malformations could be predominantly venous, lymphatic, capillary or arteriovenous. Combined vascular malformations, often syndromic, must be searched for. Diagnosis is sometimes difficult. It is based on clinical history, aspect, evolution and radiological examinations (color-Doppler ultrasound and MRI). Treatment is often a combination of medical and surgical approaches performed by a multidisciplinary team.
