title: Primary malignant lymphoma of the trachea and subglottic region.
abstract: A 44-year-old female was admitted with the complaint of choking. On fiberbronchoscopic examination, multiple, polypoid lesions with a smooth surface were exhibited at the cervical trachea. Histological diagnosis was B-cell malignant lymphoma, diffuse, medium sized cell type (LSG classification). No other lesions were detected in the systemic evaluation. After combined chemotherapy and regional irradiation, the tumor disappeared. The clinical and pathological characteristics of this case are similar to those of malignant lymphoma of mucosa-associated lymphoid tissue (MALT).
