Vascular anomalies are a group of disorders divided into two distinct
subtypes: vascular tumors and vascular malformations. Vascular tumors
are proliferative in nature, while malformations are non-proliferative.
Simple, localized vascular malformations refer to a group of
malformations that are localized to a single area of involvement. These
simple malformations include capillary, lymphatic, venous, and
arteriovenous malformations. The pediatric hematologist and oncologist
is becoming increasingly involved in the diagnosis and management of
these disorders. This review presents four cases as a means to discuss
the diagnosis, clinical and imaging features, and management strategies
of simple, localized vascular malformations.
