A 60-year old woman with a history of nodular goiter was admitted to hospital. Fine needle aspiration cytology (FNAC) of dominant nodule was suspicious of papillary thyroid carcinoma. Preoperative serum calcium level was normal in biochemical analysis. Cervical exploration revealed an aberrant tissue inferior to left thyroid gland which was reminiscent of parathyroid adenoma or an enlarged lymphadenopathy. Total thyroidectomy and en-bloc resection of this tissue was performed. Histopathological examination of the thyroid gland and aberrant tissue revealed papillary thyroid carcinoma and parathyroid carcinoma which was silent preoperatively. As the authors, we think that any abnormally enlarged parathyroid gland detected during thyroidectomy for malignancy should raise the suspicion of a second primary in the parathyroid gland.
