EPITHELIOID HEMANGIOENDOTHELIOMA PRESENTING AS A CHEST-WALL TUMOR

We report a case of epithelioid hemangioendothelioma presenting as a c hest wall tumor. The patient had invasive bladder carcinoma and a soft -density mass protruding into the left thoracic cavity from the latera l chest wall on a computed tomographic scan. Percutaneous needle biops y was performed to obtain a definite diagnosis of the chest wall tumor . Because of an intrathoracic hemorrhage after the procedure, the pati ent underwent an emergency thoracotomy and excision of the mass with a djacent structures. Pathologic exmination demonstrated the mass to be a subpleural epithelioid hemangioendothelioma. This rare tumor has nev er been reported previously as arising from the chest wall.
