Now classification proposed by International Society for the Study of Vascular Anomalies (ISSVA) has been updated and used. According to the classification, cutaneous vascular anomalies described in this textbook could be classified as follows. Note that some syndromes demonstrate various types of hemangiomas and vascular malformations. Vascular Malformations and Hemangiomas What are hemangiomas and vascular malformations? Hemangiomas.

Vascular malformations and hemangiomas altogether as vascular anomalies remain one of the enigmas in modern medicine. Given the pau-city of knowledge in this field, employing an ap-propriate diagnostic approach to vascular anom-alies is a major challenge for most physicians.

Anomalies (Table 1).1 This system includes infantile hemangioma (IH) among the vascular neoplasms, which are lesions characterized by abnormal proliferation of endothelial cells and aberrant blood vessel architecture. In contrast, vascular malformations are structural anomalies and inborn errors of vascular morphogenesis. Although IH is the Cited by: Vascular anomalies are congenital errors in vascular development. They frequently involve the head, neck, and oral cavity. Subdivided into vascular tumors (hemangiomas) and vascular malformations, vascular anomalies remain poorly understood.

In , Mulliken and Glowacki proposed a biological classification of vascular birthmarks on the basis of their clinical manifestations, histopathologic features, and natural history. While infantile hemangiomas represent vascular tumors evolving a few weeks after birth, vascular malformations VMs are present at birth and grow proportionally with the growth of the child. VMs have normal endothelial turnover and do not spontaneously regress. Imaging findings do not provide discrete differentiating features of one type of lesion over another. Understanding the current nomenclature in relation to previous literature is necessary for consistent description [ Table 1 ]. The life cycle of a hemangioma differs from that of most tumors in that it demonstrates a phase of rapid proliferation followed by slow spontaneous involution, and in most cases, complete resolution. The mechanisms that control the involution of hemangiomas are poorly understood. Genetic techniques have been useful in linking some rare hereditary vascular disorders to the defective regulation of angiogenesis and vasculogenesis. In the phase of involution, there is a decrease in cellularity and an increase in the fibrous and fatty components with reduced vascularity. Imaging appearances parallel the life cycle very closely.
