A case of epithelioid hemangioendothelioma involving the left lung, the 10th thoracic vertebra, and paravertebral soft tissues is presented. Preoperative sputum cytology was thought to show adenocarcinoma. Histologic examination demonstrated an intravascular bronchioloalveolar tumor; immunohistochemical staining for factor VIII‐related antigen revealed strongly positive tumor cells. The cytomorphology of this rare neoplasm is discussed.
