The section shows alveolated lung parenchyma with a solitary, well-circumscribed, nodule showing a lobulated architecture and composed of cytologically bland mature chondroid and adipose tissue. There is no evidence of atypia or malignancy and the lesion was clear of the pathological margin.
20x H&E: The lesion is solid and sharply delineated from the surrounding parenchyma. At low power, the admixture of chondroid and adipose tissue can be appreciated.
40x H&E: At higher power, it can be seen that both chondroid and adipose components are formed by mature cells displaying no worrying cytological or architectural features.
