title: Atelectasis of the right medial basal segment mimicking primary lung cancer in an asthmatic patient.
abstract: A segmental collapse due to mucous plug in the bronchus tree may mimic malignant pathological conditions. We present a case of 58-year-old asthmatic patient with an obstruction of right medial basal bronchus due to mucous plug, which was simulating mediastinal mass. To the best knowledge, a similar case is not reported in the English medical literature.
