We report a case of thyroid cancer with primary hyperparathyroidism (1°-PHP) which was found accidentally during the examination of thyroid cancer. A 56-year-old woman was pointed out to have an anterior cervical mass, and was admitted to our department under a diagnosis of thyroid cancer. The patient complained of no subjective symptoms. Preoperative examination for thyroid cancer revealed an increased serum calcium (11.2 mg/dl). Increased serum parathyroid hormone level and urinary output of calcium were also observed, leading to a diagnosis of 10-PTH. Total thyroidctomy with bilateral modified neck dissection and extirpation of right lower parathyroid gland were performed. Histopathological diagnosis was bilateral papillary thyroid cancer and parathyroid adenoma. Serum calcium level decreased soon after operation.
It is usual that thyroid tumors are found during the examination or operation of 10-PHP. On the contrary, we must take care of serum calcium level not be overlook probable 1°-PHP when we treat the thyroid tumors.
