[A case of chronic tuberculous pyothorax associated malignant lymphoma].
The patient was 69-year-old male. He has a history of treatment for tuberculosis by artificial pneumothorax about 47 years ago. He was admitted an another hospital under the diagnosis of tuberculous pyothorax. He was transferred to our hospital because of chest pain and fever. Laboratory findings on the admission were as follows: ESR was 120 mm/hr, CRP was 20.22 mg/dl and other data were almost within normal limits. Chest X-ray showed a massive shadow in the right lower lung field, adjacent to the chest wall. Computed tomography (CT) showed tumor shadow with low density and invasions into the adjacent chest wall. Histological examination of surgically excised tumor biopsy revealed malignant lymphoma. The patient's condition improved and the size of tumor decreased temporarily by chemotherapy. Then, he began to complain of chest pain and high fever, and tumor in the chest wall invaded into the whole chest wall. He died of disseminated intravascular coagulation despite continuing chemotherapy. Postmortem examination revealed the following findings : the tumor existed mainly in the parietal pleura or the chest wall, adjacent to the lesion of pyothorax, and immunohistochemical examination showed that tumor was malignant lymphoma, diffuse, large B-cell type. Recent studies have shown a close association between EBV infection and pyothorax-associated lymphoma. We have to keep in mind the possible development of malignant lymphoma following tuberculous pyothorax, when we see patients complaining of fever or chest pain with tuberculous pyothorax.
