A 55-year-old man was admitted because his chest X-ray showed an abnormal shadow in the right hilar region. Transbronchial lung biopsy specimens examined immunohistochemically showed infiltration by T and B lymphocytes and plasma cells, and cytological tests of specimens obtained by transbronchial aspiration revealed small cell lung cancer.
Because of tumor invasion of the mediantinum, surgery was performed after chemotherapy. Right pneumonectomy was performed because the right upper bronchus was involved in the tumor. The pathological examination showed malignant lymphoma. No metastatic lesions were found in the mediastinal and hilar lymphnodes.
He died of interstitial pneumonia during a course of postoperative chemotherapy. No evidence of recurrence or metastasis of lymphoma was found at autopsy.
We conclude that the malignant lymphoma originated in the lung.
