title: Acute carcinoid syndrome: a complication of flexible fiberoptic bronchoscopy.
abstract: We report the case of a patient with functioning bronchial carcinoid tumor found as a solitary nodule. Acute carcinoid syndrome developed during transbronchial biopsy, and life-threatening hypotension occurred during operation. We emphasize that carcinoid tumors should be considered in the differential diagnosis of solitary nodules, and such a complication should be kept in mind when endobronchial or transbronchial biopsy is performed.
