Abstract
We report a case of malignant lymphoma with bronchial involvement in a 35-year-old male patient. On admission, chest X-ray revealed enlargement of bilateral hilar lymph nodes and expansion of the superior mediastinal space. CT and MR images showed that the tumor shadow appeared to wrap around the left and right main bronchi. Bronchoscopy revealed that the entire periphery of the left main bronchus was constricted. Transbronchial biopsy specimens, which revealed findings consistent with non-Hodgkin's lymphoma, were positive for surface markers of CD2, CD4, and CD8 and negative for those of CD19 and CD20. After MACOP-B treatment, the patient entered complete remission. He received 41.4Gy radiotherapy thereafter, and has shown no signs of recurrence during continuing follow-up.
