The simultaneous occurrence of more than two types of neoplasms is rare due to their significant phenotypic differences. Thyroid carcinoma is regularly associated with genetic alterations and endocrine syndromes. However, the etiology of the forms of papillary thyroid carcinoma (PTC)/medullary thyroid carcinoma (MTC) is still not fully understood.

Background: Mixed medullary-papillary thyroid carcinoma (MMPTC) and mixed medullary-follicular thyroid carcinoma (MMFTC) are rare variants with little known regarding behavior and prognosis.
Methods: Using the National Cancer Database (NCDB), demographics, clinicopathologic features, treatment, and overall survival (OS) from patients with MMPTC and MMFTC were compared to more prevalent subtypes.
Results: There were 296,101 patients: 421 MMPTC (0.
