[Endobronchial leiomyoma is a rare cause of recidivating pneumonia].

Leiomyomas arise from the smooth muscle cells of the lung and account for less than 2% of all benign tumours of the lung. Symptomatology is based on the degree of bronchial obstruction. Endobronchial leiomyomas often present with obstructive pneumonia and atelectasis. We present a case report of a 17-year-old woman who had pneumonia of the right lower lobe. The anamnesis revealed three previous hospitalizations over the last one and a half years due to pneumonia of the right lung. A diagnosis of primary endobronchial leiomyoma was made on the basis of histopathology and immunohistochemistry obtained during bronchoscopy.
