The association between thyroid neoplasia and intestinal polyps

Recent reports have suggested an association between familial adenomatous polyposis and papillary carcinoma of the thyroid. This report describes four patients, each with intestinal polyps and thyroid or thyroglossal cyst carcinoma. One patient had a medullary rather than papillary carcinoma of the thyroid and in another the intestinal polyps were due to Peutz-Jeghers syndrome. This may indicate a wider association between thyroid carcinoma and intestinal polyps than has previously been recognised.
