Alveolar soft-part sarcoma is an unusual tumor of uncertain histogenesis which usually presents as a painful mass in the right thigh in young women and progresses slowly but inexorably to death. A search of the English literature revealed only 65 cases, none of whom presented with asymptomatic pulmonary nodules. The authors recently had the opportunity to see a young man with multiple pulmonary nodules whose biopsy diagnosis revealed alveolar soft-part sarcoma. It is the purpose of this report to add this tumor to the list in the differential diagnosis of pulmonary nodules.
