[Tracheobronchopathia osteochondroplastica and coexistent mucoepidermoid carcinoma of the lung: Case report].

Pneumonia of the middle lobe that had been diagnosed by x-ray in a male patient of 51 years of age did not recede completely despite antibiotic treatment. CT showed a space-occupying growth in the middle lobe of about 1.5 cm size, with consecutive atelectasis. Bronchoscopy revealed a pronounced pattern of tracheobronchopathia osteochondroplastica, but it was not possible to confirm the middle lobe syndrome (Brock's syndrome) by histological examination. A mucoepidermoid carcinoma of the middle lobe was histologically established by thoracotomy besides the tracheobronchopathia osteochondroplastica. 9 months post-operatively there is no pointer to any recurrence or metastasising.
