Abstract

An unusual case of pulmonary alveolar soft part sarcoma is reported . A 19-year-old woman was admitted because of an abnormality in the chest X-ray, with no respiratory symptoms. The chest X-ray showed a small mass lesion in the left middle lung field . The chest CT showed a circular nodular lesion of 1 cm in size in the left upper lobe . The nodule was resected under thoracoscopic surgery and was diagnosed as alveolar soft part sarcoma . Although the tumor seemed a metastatic lesion, any other primary site was detected . It is unknown whether the tumor was primary or metastatic.
