title: Small cell lung cancer with endobronchial growth: A case report.
abstract: The current study presents a rare case of small cell lung cancer (SCLC) with endobronchial growth in a 68-year-old male. Chest CT scans revealed an ill-defined mass in the upper lobe of the right lung, with ipsilateral mediastinial lymph node swelling. An endobronchial polypoid tumor in the right B3 bronchus was located by bronchoscopic examination. The analysis of a biopsy specimen obtained from the tumor resulted in a diagnosis of SCLC. Although extremely rare, this case highlights the importance of considering a diagnosis of SCLC in patients presenting with a pulmonary tumor adjacent to the bronchus, with an endobronchial polypoid lesion.
