Bartonella species bacteremia in two patients with epithelioid hemangioendothelioma

J Clin Microbiol. 2011 Nov;49(11):4006-12. doi: 10.1128/JCM.05527-11. Epub 2011 Sep 14.


Bartonella henselae and B. koehlerae bacteremia was documented in two epithelioid hemangioendothelioma patients and B. koehlerae bacteremia in an asymptomatic partner of one of the patients. Considering the biology and clinically variable natural history of epithelioid hemangioendothelioma, these results suggest that chronic Bartonella infection could have a role in the development of this vascular neoplasm. Bartonella spp. are known to induce vasoproliferative tumors in immunocompromised patients and may play a role in the development of epithelioid hemangioendothelioma in immunocompetent patients.
