Pneumothorax as atypical presentation of bronchial carcinoid.

We present a case of pneumothorax associated with an endobronchial carcinoid tumor in a 18-year-old man with dyspnea and chest pain. Additional tests were done, identifying in the chest roentgenogram a complete left pneumothorax with persistent leak, which was confirmed by computed tomography of the chest, and also finding an endobronchial lesion that limited the complete reexpansion of the left lung. Surgical excision was performed, and the lesion was identified as a typical bronchial carcinoid, with satisfactory outcome after the intervention.
