  • Title: Large bronchial granular cell tumor.
    Author: Shinohara H, Tsuchida M, Hashimoto T, Satoh S, Takeshige M, Hayashi J.
    Journal: Gen Thorac Cardiovasc Surg; 2009 Sep; 57(9):484-7. PubMed ID: 19756937.
    Abstract:
    We report a 20-year-old woman who underwent complete resection of a granular cell tumor (GCT). On chest computed tomography (CT) scan, a mass with a maximum diameter of 36 mm at the lower bronchus with atelectasis of the right lower lobe was noted. Bronchoscopic examination revealed a whitish mass in the truncus intermedius, and the middle and lower bronchus were unable to be seen. A cytopathological examination of the mass revealed GCT. A right middle and lower lobectomy was performed via a posterolateral thoracotomy. Microscopically, the tumor was composed of polygonal cells with oxyphilic granular cytoplasm and small ovoid nuclei. The cytoplasm of the neoplastic cells was positive for S-100 protein and neuron-specific enolase. The patient's postoperative course was uneventful, and she was asymptomatic after 4 months. A large bronchial GCT is rare, which is why we report this case.
