title: Angiosarcoma in the lung.
abstract: Angiosarcoma involving the lung is a rare disorder and its clinical features are not well known. We conducted a retrospective analysis of 15 patients seen at our institution from 1950 to 1990 in an attempt to better characterize the spectrum of clinical and radiographic findings of angiosarcoma in the lung. No documented case of primary angiosarcoma of the lung was seen. The diagnosis of metastatic angiosarcoma to the lung was made antemortem in 12 of 15 cases, either by lung biopsy specimen (5 patients), biopsy evidence of metastatic disease elsewhere with abnormal chest radiograph (4 patients), or a compatible clinical picture in a patient with previously documented angiosarcoma arising in an extrapulmonary site (3 patients). The median age at the time of diagnosis was 45 years with the most common presenting symptom being hemoptysis (7 of 15 patients). Other presenting complaints included weight loss (6 of 15), cough (4 of 15), and chest pain (4 of 15) occurring 6 weeks to 1 year prior to diagnosis. Chest radiographs frequently disclosed multiple pulmonary nodules (11 of 15). Primary origins of the angiosarcoma most commonly included the heart and breast. Metastatic sites other than the lung included the pericardium, liver, spleen, kidney, adrenal gland, bone, and brain. The prognosis is generally poor, with our study population surviving an average of 9 months after diagnosis.
