A Case of Primary Tracheal Lymphoma of a 65-year-old Female: Extremely Rare Primary Localization of a Diffuse Large B-cell Lymphoma

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.
