[Selected biological markers in various vascular lesions of the head and neck].

Vascular anomalies are divided according to the contemporary system of classification into two groups: tumors and malformations. However, there is no consensus on juvenile angiofibroma's place in that system. The general characteristics of selected markers of angiogenesis and tissue remodeling are presented in the series in the context of current knowledge in the field of pathophysiology of vascular lesions. The mentioned markers are currently the subjects of multidirectional studies in oncology, as they take part in the process of neoangiogenesis and proliferation of tumors. Nevertheless, they have not been widely examined in vascular lesions. The indirect goal of that series is to indicate the possible research direction on vascular lesions to determine their molecular profile, to create a more specific system of classification, and above all to develop new diagnostic and treatment methods.
