Epithelioid hemangioendothelioma: a case with large solitary pulmonary mass and hypertrophic osteoarthropathy

We describe a case of pulmonary epithelioid hemangioendothelioma [PEH], previously known as intravascular bronchoalveolar tumor, in a 48-year-old woman with an initial diagnosis made by CT-guided transthoracic needle biopsy. This is a rare disease, with approximately 50 cases described in the literature. To our knowledge, this has not been previously described in the English-language literature. This tumor can affect multiple organs. PEH is usually multifocal or small sized; hypertrophic osteoarthropathy is uncommon. This patient presented with hypertrophic osteoarthropathy and large solitary pulmonary mass, rare presentations of this uncommon tumor
