In their literature reviews, Venegas et al. and Oide et al. reported that tracheal and bronchopulmonary GTs predominantly affect male patients (65% and 72%, respectively); with 80% and 64% of cases occurring in individuals aged 40 and older [1, 2]. Consistent with these findings, our case series demonstrated that endobronchial GTs predominantly occur in male adults 30 to 70 years old. Additionally, all cases in our series involved otherwise healthy adults without underlying lung disease.
