A case report of primary anaplastic large cell lymphoma arising from the trachea

Primary malignant tumors of the trachea are rare, accounting for about 0.1–0.4% of all malignancies (1-3). The most common pathology is squamous cell carcinoma, followed by cystadenoma (Table 1) (1,4). Although extranodal lymphoma is commonly encountered, lymphoma presenting in the large airways are incredibly rare (5), constituting less than 3% of tracheal tumors. Less than 10 cases have been reported in the literature to date (6,7). Presenting symptoms can be mistaken for other entities, and imaging can play a vital role in diagnosis and management. Here, we present a case of anaplastic large cell lymphoma (ALCL) of the trachea with an emphasis on the imaging features of this entity and a discussion of treatment complications
