Primary Hyperparathyroidism, Concomitant Thyroid Papillary and Follicular Carcinomas on the Background of Hashimoto s: Interplay?

Concomitant appearing of varied histological types of primary, well differentiated thyroid carcinoma simultaneously in the same patient is a rare condition. Furthermore, Hashimoto s thyroiditis (HT) and hyperparathyroidism due to parathyroid adenoma were both described as associated with thyroid cancer. Hereby, a case report of a patient with various, synchronous, thyroid disorders. A 53-year-old female presented with both papillary and follicular carcinoma of the thyroid, HT and primary hyperparathyroidism, all these pathologies occurring synchronically. Although, what may be anecdotal, propose an intriguing theoretical possible interplay. In addition, a short relevant auxiliary review and discussion is presented.
