title: [Case of both T- and B-cell markers positive pyothorax-associated lymphoma].
abstract: A 84-year-old man with a history of pulmonary tuberculosis admitted to our hospital due to painful swelling in right front chest wall. His chest CT shows a tumor at right chest wall and right chronic empyema. Histopathologic findings from biopsy revealed both T- and B-cell markers positive non-Hodgkin's lymphoma, and we diagnosed him pyothorax-associated lymphoma. Irradiation resulted in tumor shrinkage, and a pain of tumor disappeared. T- and B-cell markers positive pyothorax-associated lymphoma is rare.
