Synchronous mixed medullary-papillary carcinoma and papillary multifocal carcinoma of the thyroid with cervical lymph node metastases.

ABSTRACT

Key Clinical Message The occurrence of simultaneous multifocal papillary thyroid carcinoma and mixed medullary-papillary carcinoma, as far as we know, has not been previously described. We suggest the surgical approach to be driven by the medullary component. Abstract Patient underwent total thyroidectomy with central compartment lymph node dissection. Histological examination revealed a simultaneous multifocal papillary thyroid carcinoma and mixed medullary-papillary carcinoma. He was disease-free at 1-year-follow-up.
