Endobronchial non-Hodgkin's lymphoma (NHL) is rare and poses a diagnostic challenge if there is pre-existing lung disease, like idiopathic interstitial lung disease (ILD). We report refractory cough due to isolated endobronchial non-Hodgkin's low grade B-cell lymphoma in a 57-year-old female with ILD. Local diathermy fulguration of endobronchial NHL resulted in remission of cough and there was no recurrence or spread of endobronchial NHL at four years of follow up.
