ABSTRACT

A 65-year-old man presented at a local hospital with exertional dyspnea and fever. He was diagnosed with bacterial pneumonia and hospitalized; however, there was no improvement in his condition, and he was transferred to our hospital for further investigation. Diffuse ground-glass opacity on chest CT scan was observed, accompanied by hypoxemia. Pulse steroid therapy was administered because of a differential white blood cell count with 71% lymphocytes in bronchoalveolar lavage fluid. His respiration improved; however, the symptoms again aggravated. PET-CT revealed FDG accumulation in the spleen and dorsal hypodermis, and a biopsy of subcutaneous nodules confirmed a diagnosis of diffuse large B cell lymphoma. Here we report a case of secondary malignant pulmonary lymphoma presenting with diffuse ground-glass opacity and acute pulmonary failure because of lung infiltration.
