A patient with endobronchial granular cell tumor incidentally discovered during a careful examination of pulmonary tuberculosis

The patient, a 54-year-old male, had a cough since January 2004. A health examination demonstrated an abnormal shadow in the thoracic region, and the patient was referred to our Respiratory Medicine Department in late-March, 2004. Since an infiltrative shadow was observed in the right upper S² by imaging of the thoracic region, the patient was admitted for further evaluation. No abnormalities in the right upper lobar branch were detected in the visual field on TBLB, but the patient was diagnosed as having pulmonary tuberculosis based on examination of the bronchial wash in the right B². A white flat protruding lesion was observed at the entrance of the right B⁹, ¹⁰, and the lesion was diagnosed as granular cell tumor in the bronchial tube by biopsy. Since the tumor with a diameter of approximately 5 mm was relatively small and coexisted with pulmonary tuberculosis, the patient has been under observation while undergoing treatment with 4 antituberculosis drugs in the outpatient department.
