The case of a 66 years old male patient with multiple tracheal and bronchial lesions of non-Hodgkin lymphoma is reported. This was a disseminated form of low-malignancy lymphoma, as shown by histological findings. The lesions disappeared after 10 courses of chemotherapy, and no sign of recurrence was observed during a 3 years' follow-up. It is concluded that the prognosis of this disease depends on histology rather than on anatomical spread.
