#2156 Two Cases Synchronous Atypical Parathyroid Adenomas and Papillary Thyroid Carcinoma

Introduction: A literature review revealed a prevalence of approximately 3% of nonmedullary thyroid cancer, which was found in patients operated on for primary hyperparathyroidism (pHPT). Papillary thyroid carcinomas(PTC) is a malignant epithelial tumour. PTC represent up to 87% of all thyroid carcinomas. Atypical parathyroid adenoma(APA) are a subset of parathyroid neoplasms that exhibit some of the features of parathyroid carcinoma but lack unequivocal invasive growth. APA represents about 0,5-4% of cases of pHPT. As a group, they may be considered tumors of uncertain malignant potential.
