A rare case of hypoparathyroidism, Graves’ disease and thyroid papillary carcinoma

The prevalence of hypoparathyroidism in the USA is 37 out of 100,000. Hypoparathyroidism is divided into primary and acquired. It occurs when there is inadequate secretion of PTH leading to the decrease of calcium as well as the increase of phosphate level. Coexistence of any cases of hypoparathyroidism, Graves’ disease and papillary thyroid carcinoma (PTC) has never been reported in the literature before. The rare case introduced here is a 42 years old woman with the history of primary hypoparathyroidism since 18 years ago that developed Graves’ disease about 14 years after the onset of the disorder and underwent a thyroid surgery due to PTC 2 years later.
