An unusual presentation of parathyroid adenoma--a case report.

A case of intrathyroid parathyroid adenoma which clinically and cytologically mimicked thyroid tumor is presented. The patient was normocalcemic inspite of clinical and radiological features suggestive of hyperparathyroid bone disease. The adenoma showed an area of infarction presumably accounting for the normocalcemic primary hyperparathyroidism. The case is reported for its unusual presentation.
