Vascular anomalies are categorized into vascular malformations and vascular tumors. Skin defects and ulcerations occur in many vascular tumors (up to 25% in infantile hæmangiomas). Though rare in vascular malformations, superficial erosions (intertriginous dermatitis) are seen in lymphatic malformations and frank ulcerations can occur in arterio-venous malformation (AVM). These ulcerations are difficult to heal. Excision with skin grafting or Interventional Radiological (IR) approaches can be a treatment option. The efficiency of IR approach is illustrated in three patients with AVMs and in one case of venous malformation. In one case presentation, a large ulcer occurred on an amputated foot stump associated with a complex AVM. The treatment was by embolo-therapy alone. In other two cases there were digital (finger) AVMs and in one case it was a venous malformation of the second toe. All lesions were associated with small punctate ulcers and were treated by sclerotherapy.
