[Plastic bronchitis and mucoid impaction--uncommon disease syndromes with expectoration mucus plugs].
Mucoid impaction and plastic bronchitis are relatively rare disorders caused by the formation of obstructive airway plugs. We observed from February 1999 to June 2000 seven patients with mucoid impaction and one with plastic bronchitis. In the group of mucoid impaction there were 4 patients with bronchial asthma and 3 without history of lung disease. At the admission to hospital all patients suffered from cough, chest pain and effort dyspnea. Two of them expectorated during cough "bronchial casts". The chest X-ray of 5 patients revealed atelectasis of one of the lung's lobes and diffuse opacities in 2 others. In 4 cases during bronchoscopy one bronchus and in another three--numerous bronchi were obstructed with mucoid casts. Removing of the casts caused both the improvement of the patients' condition and withdrawal of atelectasis in 4 cases. In 5 patients the final diagnosis was allergic bronchopulmonary aspergillosis and in two mucoid impaction in the course of asthma without aspergillosis. Plastic bronchitis was observed in 44 years old man, who expectorated white, branching, bronchial casts for three months. On admission he was in respiratory failure. The chest X-ray revealed diffuse alveolar infiltrates and HRCT glass-ground opacities in both lungs and bronchiectasis in the middle lobe. The bronchofiberoscopy disclosed diffuse tracheobronchitis with casts occluding the middle lobe bronchus. Microscopic examination of the removed casts showed aggregates of mucus, macrophages, neutrophils and cells of respiratory epithelium. Precipitins against Aspergillus fumigatus were not found. Staphyloccocus coagulase (-) was cultured from urine and sputum specimens. We administered Vancomycin with Netylmycin, acetylocysteine, oxygen therapy and humid inhalation and the patient recovered. HRCT made six months after admission revelated total withdrawal of glass-ground opacities. The pathogenesis of plastic bronchitis in this case was unclear.
