Thyroid glands from 2 1 5 patients, aged 19 to 88 years, without known thyroid disease, were serially sectioned at 2 -3 mm intervals and microscopically examined for occult disease.
Glands were normal in 32.5%, while nodules were observed in 60% and adenomas in 13%. Carcinomas were found in 20 cases (9.3%):occult papillary carcinomas in 19 (8.8%) and one medullary carcinoma.
No carcinomas were found in the thyroids of 15 patients less than 40 years of age.
There were no significant differences in frequency of occult carcinomas between female and male patients and, for patients over 40 years, with increasing age.
Of the 19 papillary tumours more than one focus was found in six cases (a total of 28 foci).
