Four cases of Primary Pulmonary Lymphoma and review of the literatures
Objective To study the clinical characteristics, diagnosis and treatment of primary pulmonary lymphoma(PPL). Methods A retrospective review of 4 PPL cases was performed, and relevant literature was reviewed. Result PPL was easy to be misdiagnosed due to non specific clinical and imaging manifestations. The invasive biopsy is the main diagnosis approach. The positive incidence of fiber-bronchoscopic biopsy is low. Conclusion Appropriate invasive biopsy is necessary for early diagnosis of PPL.
