A Rare Case of Non-Hodgkin Lymphoma of the Tracheobronchial Tree

Non-Hodgkin lymphoma (NHL) is a group of malignant neoplasms originating mainly from the lymph nodes. These tumors may result from chromosomal translocations, various toxins, infections, or chronic inflammation. NHL primarily involving the tracheobronchial tree is uncommon. Surgery, chemotherapy, and radiation therapy have been used alone or in combination for treatment. Here, we report a case of NHL of the tracheobronchial tree in a seven-year-old child, which was initially diagnosed as a foreign body in the left bronchus.
