Detection of Thyroid Carcinoma During Surgical Exploration of the Neck for Primary Hyperparathyroidism

Although the pathological association of thyroid and parathyroid diseases are common, an association be-tween parathyroid adenoma and thyroid cancer is rare. Concomitant thyroid cancer in patients with pHPT has been reported at varying frequencies. We report here a case of a 55 year–old man who was diagnosed with primary hyperparathyroidism (pHPT) due to a single parathyroid adenoma, con-firmed biochemically and radiologically. At operation, a nodule in the right thyroid lobe was found incidentally and excised. Histology of the nodule revealed papillary thyroid carcinoma (fol-licular variant).
