Head and neck vascular anomalies. A multidisciplinary approach and diagnostic criteria

Abstract

Vascular anomalies represent a heterogeneous group of pathologies of the circulatory system that can affect any type of hematic and /or lymphatic vessel of different diameter or anatomic site. The extreme variability of tissue types and districts involved by these lesions determines a wide heterogeneity of clinical manifestations, resulting in involvement of different medical expertise. In this context, a commonly agreed terminology is crucial for the appropriate evaluation and multidisciplinary management of patients. The ISSVA Classification that has its roots in the previous Classification of Mulliken and Glowacky distinguishes vascular anomalies in two main groups: vascular tumors and vascular malformations. In head and neck, where vascular anomalies are the most common benign lesions of infancy and childhood, correct diagnosis with the use of unequivocal terminology is more crucial for treatment considering the relevance of structures that can be involved. The aim of this work has been to clarify information and knowledges currently available in the field of vascular anomalies. Referring to ISSVA Classification, clinico- histopathological aspects of each entity have been elucidated.
