COEXISTENCE PARATHYROID ADENOMA AND PAPILLARY THYROID CARCINOMA: 5 CASES

Aim: Our aim in this study is to present 5 cases with parathyroid adenoma and coexisting PTC accompanied by the information available in literature. Materials and methods: Of the 106 patients who had surgery for primary hyperparathyroidism at Ataturk University Medical Faculty General Surgery Department between 2006 and 2013, the data of 5 patients who had pathologically identified incidental thyroid papillary microcarcinoma after total thyroidectomy with parathyroid adenoma excision was evaluated retrospectively. Results: Two of the patients included in the study were male, 3 were female and the average age was 52.4 years. Calcium levels were high in 3 patients preoperatively. Parathyroid hormone levels were high in 4 patients. Neck ultrasonography was performed for all patients. Parathyroid scintigraphy was performed in one patient who was suspected of having a parathyroid adenoma. All 5 patients had total thyroidectomy performed with parathyroid adenoma excision. One patient later had central lymph node dissection. Temporary hypocalcaemia developed in 2 patients during the postoperative period. There was no nerve injury or permanent hypocalcemia observed. The tumor of one patient with detected papillary micro carcinoma was larger than I cm. Conclusion: The thyroid tissue should be evaluated carefully and pathological evaluation with needle biopsy should be performed in patients having surgery for primary hyperparathyroidisin.
