Airway Obstruction in a Cancer Patient: Is it Always Cancer?

Allergic Bronchopulmonary Aspergillosis (ABPA) is a common hypersensitivity to Aspergillus sp. that is well described in the literature. The populations most susceptible to developing this reaction are asthmatics and patients with cystic fibrosis (CF). The presenting symptoms can vary as ABPA is rarely described in otherwise normal individuals, however, in patients with an underlying familial predisposition to atopy, it can be seen. This case illustrates the importance of how ABPA can affect a patient who does not fit into a typical phenotypic profile.
