ABSTRACT
Cutaneous vascular tumors (CVT) encompass a spectrum of benign, intermediate and malignant tumors. Classification and nomenclature of CVTs have been evolving based on emerging clinical and molecular/genetic data. Several benign and intermediate CVTs are newly identified and characterized and remain rare in the literature. Vascular tumors can be diagnostically challenging due to overlapping morphologic and immunohistochemical features, evolving terminology, and difficult to recognize vascular nature in a subset of tumors. Using an integrated approach, accurate diagnosis is feasible and essential for optimal patient management. In this review, we summarize select CVTs to update clinical, histologic, immunohistochemical, and molecular/genetic characteristics.
