[Primary pulmonary lymphoma: a case report].

PPL is very rare in clinics, accounting for only 0.5%-1% of primary lung tumors, and can easily be misdiagnosed or missed due to the nonspecifically clinical features and imaging findings. Although the treatment of this disease has controversial, surgery and postoperative adjuvant chemotherapy are used for most patients in present. This review will report a rare case of primary pulmonary lymphoma, and discuss its diagnosis and treatment.
