A 61-year-old woman presented with dyspnea and intense cough. Chest radiography showed opacity of the entire left hemithorax and computed tomography of the chest confirmed a solid heterogeneous mass extending from apex to base, with foci of calcification and areas of low attenuation. Left upper lobe resection was performed, removing the tumor in large pieces. Histologic characteristics of the lesion were compatible with typical hamartoma. No signs of recurrence were detected 2.5 years after the operation.
