Primer pulmonalis epitheloid haemangioendothelioma@@@Primary pulmonary epitheloid haemangioendothelioma

A 49-year-old female patient was admitted in July 2009 because of cough, weight loss and effort dyspnoe. Chest X-ray and CT showed multiple bilateral nodules which have been identified earlier and these nodules were unchanged. However, there was a new parenchymal lesion in the right upper lobe, and new right hilar and mediastinal lymphadenomegaly was also found. Sample was taken by bronchoscope and the pathological diagnosis was pulmonary epitheloid haemangioendothelioma. This rare endothelial tumor usually affects middle-aged patients with a female predominance and it presents with chest pain, effort dyspnoe, cough, sputum, or it may remain asymptomatic. Multiple bilateral nodules are usually detected by radiologic examination. The diagnosis of this tumor is often challenging and, because of its rarity, it does not have any standard therapeutic regimen. Treatment can be surgery, chemo-, radio-, hormone- or immunotherapy. In order to find the most effective anticancer treatment, authors performed in vitro studies. On the basis of the results, chemotherapy was initiated which resulted in a partial regression.
