title: Metastatic pulmonary epithelioid hemangioendothelioma with peculiar radiographic features.
abstract: We report a case of a pulmonary epithelioid hemangioendothelioma presenting as a solitary pulmonary nodule with subsequent systemic spread, including histologically documented gingival metastasis. Chest radiography and computed tomography at initial evaluation showed a solitary 2 cm pulmonary nodule, associated with pleural indentation and vascular convergence. The tumor later spread systemically, including multiple pulmonary nodules, bilateral pleural effusions, and gingival swelling and erosion. A biopsy of the gingival lesion showed histologic features identical to that of the lung biopsy.
