Concurrent Medullay and Papillary Carcinoma of the Thyroid
Abstract
-
The origins of medullary carcinoma and papillary carcinoma of thyroid are embryologically different. We report a case of simultaneous occurrence of medullary carcinoma and papillary carcinoma of the thyroid in the same thyroid gland. In this case, the occurrence of the two tumors may be a coincidence, does not have embryological or genetical significance.
