Abstract：Objective To analyze the clinical characteristics and misdiagnosis causes of alveolar soft part sarcoma ( ASPS) , and investigate the prevention measures of misdiagnosis. Methods The clinical data of a patient with pulmonary metastasis of ASPS misdiagnosed with tuberculosis was analyzed retrospectively, and related literature was reviewed. Results The patient was admitted for cough and expectoration for 6 months and progressive shortness of breath for 3 months. CT im-age showed diffuse pulmonary solid nodules. Erythrocyte sedimentation rate was 35 mm/h. Then the patient was diagnosed as having bilateral secondary pulmonary tuberculosis and given with anti-tuberculous therapy. At last, the patient accepted CT-guided percutaneous lung biopsy. The pathologic result was pulmonary metastasis of ASPS. After treatment with pirarubicin and ifosfamide, the condition of the patient was stable. Conclusion ASPS is rare in clinic, and lung metastasis could be the first imaging finding of ASPS that may be misdiagnosed easily. After exclusion of tumors, those cases whose pulmonary mani-festations were hypervascular metastasis changes should be suspected of ASPS, especially for adolescents and female.
