Retrospective analyses of the clinical features of LG and pathology features by open lung bio-psies were conducted. The patient was a 42-year-old female with irregular fever,and her chest X-ray and computed tomography showed nodules with cavity and pleural effusion. Open lung biopsy proved LG. LG is seldom seen in clinic. Open lung biopsy is very important for pathology diagnosis. Early diagnosis and treatment are the key to improving survival in these patients. The therapeutic effect is good.展开更多
