Background: Pulmonary vessel sarcomas are rare, and their pathogenesis is still unclear. Meth­ods: We focus on the pathologic findings of fourteen pulmonary artery and/or vein sarcomas along with clinical prognosis. Results: Nine patients were male and five were female, and they ranged in age from 26 to 72 years (mean, 47 years). There were ten cases of pulmonary artery sarcoma, three cases of pulmonary artery and vein sarcoma, and one case of pure pulmonary vein sarcoma. Ten out of the fourteen cases were associated with pulmonary thromboembolism. Microscopically, all the tumors showed an undifferentiated sarcomatous portion. There were leio­myosarcoma portions in 8 cases, malignant fibrous histiocytomatous portions in 7 cases, angio­sarcomatous differentiation in 3 cases, and osteosarcomatous portion in 1 case. All but two pa­tients died during the follow up period (range, 1 to 78 months). The mean survival time of the pa­tients who died was 14 months and the longest survival time was 78 months after surgical resec­tion. Conclusions: The current study is one of the largest single institutional reviews of pulmonary artery and/or vein sarcoma. Regardless of the histological components and macroscopic growth patterns, these rare tumors have a grave prognosis.
