Malignant tumors of the thyroid gland are the most common of the endocrine malignancies. Although, patients with thyroid cancer have high 5 years survival rate, thyroid cancer is the most seen cause of mortality among cancers of the endocrine organs. The incidence of thyroid cancer in hyperthyroid patients varies from 0.1 to 21% in the literature. We aimed in this study to analyze the frequency of coexisting thyroid cancer and hyperthyroidism in our experience.

Total 230 patients, who were operated for hyperthyroidism without the suspicion of thyroid malignancy between January 2005 and September 2010 were included in our study. Toxic multinodular goiter, toxic adenoma and Graves’ disease were diagnosed preoperatively in 187, 16 and 27 patients respectively. Histopathological thyroid malignancy was detected in 13 patients (5.7%).

Thyroid cancer with variable incidence up to 21% should be remembered in differential diagnosis of hyperthyroid patients.

Recurrent primary hyperparathyroidism is a rare entity and presents a significant surgical challenge.

We present the case of a 53-year-old female with recurrent primary hyperparathyroidism, which was caused by the very rare occurrence of a metachronous parathyroid adenoma in a supernumerary intrathyroidal parathyroid.

This unique case highlights the challenges that arise in the evaluation of recurrent hyperparathyroidism in which even a thorough preoperative evaluation including radiographic, nuclear medicine studies and fine needle aspiration cytology did not facilitate a definitive preoperative diagnosis.

The management approach for these patients requires meticulous planning, experience and appropriate use of intraoperative adjuncts to guide surgical strategy.
