The Molecular Diagnostics of Vascular Neoplasms

Surg Pathol Clin. 2019 Mar;12(1):35-49. doi: 10.1016/j.path.2018.10.002. Epub 2018 Dec 4.


In this review, we provide an update of the recently discovered, diagnostically significant genetic aberrations harbored by a subset of vascular neoplasms. From benign (epithelioid hemangioma, spindle cell hemangioma), to intermediate (pseudomyogenic hemangioendothelioma), to malignant (epithelioid hemangioendothelioma, angiosarcoma), each neoplasm features a mutation or gene fusion that facilitates its diagnosis by immunohistochemistry and/or molecular ancillary testing. The identification of these genetic anomalies not only assists with the objective classification and diagnosis of these neoplasms, but also serves to help recognize potential therapeutic targets.
