Vascular anomalies can be high-flow malformations, such as arterial (aneurysms) and arteriovenous mal-formations, or slow-flow, such as capillary, venous and lymphatic malformations; they rank fourth among the tumors of the hand.

We present our experience with a child with a venous vascular malformation, who developed, on the internal sideof the second finger of the left hand, a round-oval tumour, purplish in colour, without any visible skin changes, evaluated by Doppler ultrasound in dynamic.

For the treatment of this lesion we used an intravenous injection of a sclerosing agent.  We include a review of the literature data regarding the classification, diagnosis and management of vascular malformations.
