title: [Malignant hemangioendothelioma associated with chronic pyothorax].
abstract: A 67-year-old man was admitted to the hospital because of a fever. A chest CT scan showed multilobular heterogeneous shadows on the right side in the chest wall and the lung, but clinical examinations and examination of a biopsy specimen did not lead to a diagnosis. At autopsy, a hemorrhagic tumor was found on the right side in the chest wall. Microscopical examination showed that large atypical cells had proliferated and formed vascular structures, which were stained positively with anti-factor VIII antibody. The histological findings led to the diagnosis of malignant hemangioendothelioma. Chronic empyema-associated malignant hemangioendothelioma is rare.
