Of 71 intrapulmonary coin lesions seen at The Prince Charles Hospital during 1982–1984, 48 were primary pulmonary malignancies and six were metastases. There were two cases each of tuberculosis, cryptococcosis, hamartoma and granuloma. Overall, 76% of the lesions were malignant and only 3% were tuberculous. These findings contrast with those from the same institution published 20 years ago, when malignancy comprised only 38% and tuberculosis 27% of lesions. Malignancy now seems to be the major cause of coin lesions in Australia. In this survey, 82% of solitary pulmonary nodules that occurred in patients of over 50 years of age were malignant.
