Primary extranodal non-Hodgkin's
lymphomas comprise approximately 10% of all non-Hodgkin's
lymphomas. However, primary tracheal non-Hodgkin's lymphoma is extremely rare, being mainly
mucosa-associated lymphoid tissue lymphoma. A 65-year-old
female has dry
cough for one year. She was diagnosed as
diffuse large B-cell lymphoma via bronchoscopic-guided
biopsy. She was treated with four cycles of the R-CHOP regimen and
adjuvant radiotherapy. After completion of the combined
treatment, the
treatment response was complete remission, and the
disease free survival was 26 months.
