Abstract:
Neuroendocrine tumors (NETs) of the thyroid gland are generally considered to be derived from parafollicular endocrine or C cells and are known as medullary thyroid carcinomas. Non-calcitonin-producing NETs of the thyroid are extremely rare in occurrence and pose a significant diagnostic dilemma for the physician and pathologist. We describe a case of a 58-year-old woman who was diagnosed as having primary NET thyroid with normal calcitonin levels and Ga DOTANOC PET-CT scan findings which were done for initial extent evaluation of the disease.
