Epithelioid hemangioendothelioma - a rare pulmonary tumor.

The authors report a case of a rare pulmonary neoplasm - epithelioid hemangioendothelioma, in a 39 year-old woman, asymptomatic until December 2003, when she developed pleuritic and right-sided chest pain. The patient presented a previous chest radiograph, performed 13 years before, which showed multiple small bilateral pulmonary nodules attributed to tuberculous sequelae. The definitive histological diagnosis was made by lung biopsy through thoracotomy. The patient developed a clinical and imagiological worsening and then therapy with interferon alpha-2a was started. Even with imagiological stability of pulmonary lesions the patient remained symptomatic and died nine months after the diagnosis had been established. The authors emphasise the rarity of this type of pulmonary neoplasm and discuss its clinical presentation, histological features, treatment and prognosis.
