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 vasc...

Epithelioid haemangioendotheliomas are rare tumours of endothelial origin. They can develop in any tissue but occur principally in the lung and liver. Their usual course is a slow progression, so that they can be treated by surgery. In aggressive forms, no treatment has proved efficient to date. This study, describes a case of bilateral pleural epithelioid haemangioendothelioma that extended to...

Pulmonary epithelioid hemangioendothelioma is an uncommon lung malignancy of endothelial origin. Besides demonstrating unpredictable presentation features and prognosis, the paucity of established treatment guidelines remains a challenge in managing these patients. We present two patients. The first patient presented with chronic productive cough over 1-year duration. He was initially diagnosed...

BACKGROUND Pseudomyogenic hemangioendothelioma is a rare soft tissue tumor usually found in young adults, predominantly males. Fibrous dysplasia is a common benign bone tumor, which accounts for 5~7 % of all the primary benign bone tumors. However, pseudomyogenic hemangioendothelioma secondary to fibrous dysplasia is extremely rare. To the best of our knowledge, this is the first case of pseudo...

Hepatic hemangioendothelioma is rare. We report on hepatic hemangioendotheliomas in 2 young infants, with initial manifestations of respiratory distress and congestive heart failure. Serum alpha-fetoprotein (alphaFP) level was as high as 26,343 microg/l at 14 days old in 1 case, but was only 18 microg/l in the other case. The 2 patients were treated with prednisolone and hepatic artery ligation...

BACKGROUND Polymorphous hemangioendothelioma is a rare vascular tumor of borderline malignant potential and only 10 cases have been described in the literature so far. METHODS AND RESULTS We report a case of nodal and extranodal polymorphous hemangioendothelioma and review the literature. A 66-year-old man with an unremarkable past medical history was admitted for a left submandibular mass. T...

Epithelioid hemangioendothelioma is a rare vascular tumor with cytologic behavior between angiosarcoma and hemangioma. We present the case of a 58-year-old male with primary epithelioid hemangioendothelioma of the distal radius measuring 6.2 × 5 cm with extension into the pronator quadratus and brachioradialis muscles. We discuss our approach to performing a limb-sparing resection combined with...
