Pulmonary Malignant Lymphoma Presenting as a Cavity Containing Nodule

━━ Background. Pulmonary malignant lymphoma is a rare disease. Diagnosis is difficult since it has various manifestations. Case. A 56-year-old man was referred to our hospital because a nodule on chest X-ray. Chest CT showed a nodule with a cavity in the left upper lobe. Lung cancer was suspected and he was operated on diagnosis and treatment. The resected specimen was diagnosed as pulmonary malignant lymphoma. After sur-gery he received chemotherapy. He is alive without any evidence of recurrence. Conclusion. We report a surgical case of pulmonary malignant lymphoma with cavity, and review some case reports. Pulmonary malignant lymphoma presents various manifestations; therefore, it should be included in the differential diagnosis of nodules. For a nodule with a suspicious of malignancy, surgical resection can be one of choices for histopathological diagnosis and treatment.
