Endobronchial malignant lymphoma: unusual manifestations--a report of two cases.

Two unusual manifestations associated with endobronchial malignant lymphoma are reported. A 58-year-old white female was first seen with massive hemoptysis requiring blood transfusion and pneumonectomy for histiocytic lymphoma (large cell type). The second case was that of a 47-year-old black male treated previously for poorly differentiated lymphocytic lymphoma (medium-sized cell type) who had a relapse in the lungs. Increasingly copious sputum production led to respiratory distress which required extensive radiation therapy and chemotherapy for its control.
