Metachronous Follicular Variant of Papillary Thyroid Microcarcinoma in a Case of Medullary Carcinoma Thyroid
Abstract
Medullary carcinoma and papillary thyroid carcinoma arise from the different cells. Simultaneous occurrence of both types is rare. Medullary carcinomas are characterised by calcitonin positivity. CK-19 is being touted as a upcoming marker for papillary carcinoma thyroid. This case highlights the utility of IHC to detect the metachronous follicular variant of papillary thyroid carcinoma in a follow up case of medullary carcinoma thyroid.
