Type two or localized endobronchial non-Hodgkin lymphoma.
We present chest x-ray, chest CT, and FDG PET images of a patient diagnosed with endobronchial lymphoma. The commonly involved thoracic structures in non-Hodgkin lymphoma are mediastinal lymph nodes. Non-Hodgkin lymphoma involving the tracheobronchial tree is rare. Localized primary endobronchial lymphoma confined to the tracheobronchial tree with no dissemination classified as type-2 is extremely rare. This is a report describing the type-2 endobronchial DLBCL. The patient also had a history of rheumatoid arthritis and was treated with methotrexate for 10 years. The other interesting aspect of this case is its association with rheumatoid arthritis and methotrexate treatment. Although there are reports documenting this type of association in the literature, there is almost no documented evidence of this association specifically with type-2 endobronchial non-Hodgkin lymphoma.
