title: Anaplastic large cell lymphoma presenting as an endobronchial polypoid mass.
abstract: We present a case of CD30+ anaplastic large cell lymphoma (ALCL) with a unusual endobronchial polypoid mass. There was para-aortic lymphadenopathy on the CT scan. This case illustrates that ALCL should be included in the differential diagnosis of endobronchial mass lesions.
