Primary lung tumours are uncommon in childhood. Among these tumours, endobronchial masses are even less common and, among benign tumours, inflammatory pseudotumours and hamartomas have the highest incidence in children. We present the case of a 2.5-year-old girl with a left endobronchial chondromesenchymal hamartoma with obstruction of 90% of the bronchial lumen. Complete resection of the endobronchial mass was performed by rigid bronchoscopy and application of topical mitomycin C. After tumour resection and a 12-month follow-up, the patient has shown a favourable outcome with immediate disappearance of respiratory symptoms. Successive fibreoptic bronchoscopies have shown no residual tumour.
