A 64 year-old man was treated 40 years ago with artifical pneumothorax for pulmonary tuberculosis. He came to our hospital complaining of bloody sputum, and left chronic pyothorax was diagnosed. Thoracic drainage and continued administration of antibiotics unfortunately led to persistent bloody fluid, requiring thoracoplasty for hemostasis. No definite diagnosis was made before thoracoplasty. The histological diagnosis was diffuse large cell, B-cell type malignant lymphoma in a portion of the pyothoracic wall. Chemotherapy with cyclophosphamide, epirubicin, vincristine and prednisolone was administered postoperatively. The patient is now under ambulatory treatment 10 months postoperatively.
