Vascular malformation of the upper lip

Abstract

Vascular anomalies account as one among the most difficult diagnostic and therapeutic enigmas that can be encountered in the practice of medicine. These lesions are the result of an embryonic abnormality of the vascular system. The main characteristic feature of vascular malformations is that they never show the signs of involution. It is the most common neoplasm of the infancy. The clinical presentations are extremely protean and can range from an asymptomatic birthmark to life-threatening hemorrhage. Here, we present a case of vascular malformation in the upper lip of a 4-year-old patient.
