title: Primary pulmonary lymphoma: report of three cases and a brief review of the literature.
abstract: We report three patients with primary pulmonary non-Hodgkin's lymphoma which is a rare extranodal lymphoid neoplasm. In these patients, both the history and physical findings were vague and minimal. The laboratory findings were normal apart from chest radiographic abnormalities and serum gammopathy in two cases. All three patients underwent several diagnostic procedures before conclusive results were obtained from thoracotomy specimens. Histology revealed small lymphocytic infiltrate of the pulmonary parenchyma with nodal involvement in all three cases. All three patients had surgical resection and two received adjuvant chemotherapy. They are all alive and symptom-free at 92, 51 and 12 months, respectively, after diagnosis.
