The Co-Occurrence of Medullary and Papillary Thyroid Carcinoma—A Literature Review Based on a Case Report

Abstract

Conclusion: Simultaneous occurrence of MTC and PTC seems to be rare, but recent literature suggests that simultaneous occurrence is probably more frequent than initially thought. Preoperative calcitonin can be helpful in the diagnostic workup of thyroid nodules. Due to different treatment strategies, precise histological differentiation of potential lymph node metastasis is essential.
