Hamartoma in a 62-year-old patient. (i) Contrast-enhanced CT scan showing a lesion (arrowhead) with popcorn-like calcification and fat-tissue attenuation, consistent with hamartoma. (ii) Endobronchial involvement produces air trapping in the anterobasal segment because of valve effect. (iii) Gross pathology specimen showing a multilobulated tumour lesion that combines adipose (arrowheads), cartilaginous (stars) and epithelial tissue invaginations (arrow) consistent with hamartoma. (iv) Same findings are shown in the photomicrograph (original magnification, 4×; haematoxylin-eosin stain)
