Overview

Vascular anomalies constitute a wide array of disorders ranging from benign lesions such as infantile hemangioma to aggressive malignant tumors such as angiosarcoma. Commonly used misnomers and confusing nomenclature has often presented difficulties for accurate diagnosis and appropriate management. International Society for the Study of Vascular Anomalies (ISSVA) has now classified vascular anomalies into vascular tumors and vascular malformations with an unclassified category for lesions that show clinical and histological characteristics unique from disorders classified in vascular tumors and vascular malformations.

-* CLOVES is an acronym for [[congenital]] lipomatous overgrowth, [[vascular malformations]], [[epidermal nevi]], skeletal and spinal anomalies. [[Vascular malformations]] in this [[syndrome]] include [[venous]], [[capillary]] and [[lymphatic]] [[malformations]] with or without combined [[arteriovenous malformations]]. [[Pulmonary thromboembolism]] and [[respiratory]] failure are the cause of [[mortality]] in majority of the [[patients]].
