Plastic bronchitis, causing airway obstruction, is a rare condition, especially in adults. In this paper, an adult male patient with heart failure, viral hepatitis, and a history of previous pneumonia, and expectorating white, plaque-like secretions for the last 6 months is presented along with the review of the relevant literature. The material expectorated by the patient was evaluated; macroscopically, this material was observed to be identical to the shape of bronchial branching. Steroid treatment was commenced after the diagnosis was established, resulting in the nearly total disappearance of the expectorated material.
