Epithelioid Hemangioendothelioma With a Novel Chromosomal Deletion and an Aggressive Clinical Course: A Case Report...

Epithelioid hemangioendothelioma (EHE) is a rare neoplastic process arising from the endothelial lining of virtually any blood vessel, with varying degrees of metastatic spread. In the following case report, the clinical course and treatment stratification are detailed for a 59-year-old female who originally presented with cervical radiculopathy and was found to have aggressive-type EHE refractory to multiple lines of therapy. In doing so, a novel deletion of the long arm of Chromosome 16 at Position 24, in all cells analyzed, ISCN Karyotype: 46,XX,del(16)(q24)[10] is also identified and may contribute to a more aggressive disease presentation. Ultimately, further scientific contribution is provided by this report to the otherwise limited understanding of this unique malignancy.
