title: [Parathyroid adenoma disclosed by a cold nodule on thyroid scintigraphy. 2 cases].
abstract: Two unusual cases of parathyroid adenoma were diagnosed in different circumstances. In the first case, pathological examination of a thyroid lobectomy specimen disclosed a large parathyroid adenoma. In the second case, the association of clinical and biological manifestations of hyperparathyroidism with a "cold" nodule of the right lobe suggested the diagnosis which was confirmed by surgery and pathological examination. In addition to the classical causes of "cold" thyroid nodules, a large parathyroid adenoma should be considered. Routine investigations for clinical and biological manifestations of such an adenoma are advocated.
