Abstract

Introduction: Thyroid cancer is the most common cancer of endocrine system. Hyperparathyroidism is also a common endocrine disease. About 80% of primary hyperparathyroidism patients have parathyroid adenoma. The simultaneous occurrence of hyperparathyroidism due to parathyroid adenoma and papillary thyroid carcinoma is a rare condition. Presentation of case: We report a rare case of a 46-year-old woman presented with cyanosis and fatigue. During the examination, hyperparathyroidism was detected with elevated blood calcium and parathyroid hormone levels. Ultrasound revealed a 2.2cm parathyroid adenoma and a 3mm thyroid nodule on the contralateral side. The patient underwent surgery to evaluate tumors and treatment. Surgery included left lobectomy with isthmectomy, central neck dissection, and resection of the right parathyroid adenoma. Postoperative histopathology confirmed papillary thyroid carcinoma and parathyroid adenoma. Conclusion: Papillary thyroid carcinoma concurrent with parathyroid adenoma and hyperparathyroidism is a rare condition. It can be effectively treated through surgical removal of the parathyroid adenoma and the extent of thyroidectomy depending on the stage of cancer. Careful preoperative and intraoperative assessment of both the parathyroid and thyroid glands helps prevent missing concurrent nodules.
