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

Anaplastic large cell lymphoma (ALCL) is an aggressive non-Hodgkin’s lymphoma. Its presentation as an isolated primary lesion in the airway is extremely rare and not often considered in the differential diagnosis of airway lesions. Thus, it is important to be aware of its presenting manifestations, imaging features and treatment complications. Here, we report a case of pathologically confirmed tracheal-based ALCL. We especially focus on presenting the salient imaging features of this entity and the associated clinical and pathological findings of this rare large airway disease.
