Multiple pulmonary cavities as the prominent manifestation of diffuse large B-cell lymphoma: a case report.

A 60-year-old man complaining of fever, lacking in strength and with poor appetite for half month, was admitted to our Department of Infectious Diseases and Hepatic Diseases. The patient's chest computed tomography revealed multiple cavities in the lungs. And he was diagnosed with diffuse large B-cell lymphoma following the positron emission tomography-computed tomography scan and laparoscopic lymph node biopsy. His symptoms and the pulmonary cavity lesions improved significant after eight cycles of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone chemotherapy.
