A comprehensive review of all the vascular proliferations involving the skin and subcutaneous tissue, including recently described disease entities. Superbly illustrated with both clinical and histopathologic photographs, the book moves from a proposed new system of classification and nomenclature for vascular neoplasms, to a full discussion of benign and malignant proliferations, including hamartomas, benign neoplasms, malignant neoplasms, and several related newly reported diseases. The authors describe in-depth the clinical and morphologic aspects of each entity and detail their clinicopathologic correlation, differential diagnosis, prognosis, and therapy.
