Abstract：Objective To analyze diagnosis and treatment characteristics, misdiagnosis causes of primary pulmonary lymphoma ( PPL) , and propose preventive measures. Methods Clinical data of one case of primary pulmonary lymphoma misdiagnosed as lung cancer in our hospital was retrospectively analyzed with a review of literature. Results The patient had recurrent cough more than one year, and exacerbated for 10 days. Diagnosed as having lung cancer with pulmonary metastasis through chest CT in other hospital, she was finally transferred to our hospital. Contrast chest CT showed multiple tumors in both lungs, and the largest is located in the left upper lobe, surrounded by ground-glass opacity. Fiberoptic bronchoscope was used to check every lumen, no obstruction and neoplasm were found. B-type ultrasound revealed no enlarged superficial lymph nodes and retroperitoneal lymph nodes. P-antineutrophil cytoplasmic antibody and C-antineutrophil cytoplasmic antibody were all negative. She was diagnosed with PPL by lung biopsy and pathological examination through percutaneous lung puncture. After 6 cycles of chemotherapy, the patient was in a stable condition. Conclusion PPL may be misdiagnosed easily, because it is rare in clinic. Multiple pulmonary nodules and masses should be highly suspected of PPL, and lung biopsy is significant for reducing misdiagnosis.
