title: Sarcoidosis presenting as cold thyroid nodules: report of two cases.
abstract: Sarcoidosis is a systemic disease characterized by noncaseating granulomas. Thyroid involvement is rare in sarcoidosis. In this paper, two sarcoidosis patients who demonstrated cold thyroid nodules are presented. A 42-year-old woman presented with multinodular goiter and was diagnosed as having sarcoidosis when noncaseating granulomas were observed during the pathological examination of the thyroidectomy specimen. Enlarged mediastinal lymph nodes were observed in the routine preoperative chest X-ray in another 53-year-old woman, while she was being prepared to undergo a thyroidectomy. The pathological examination of the thyroid specimens showed noncaseating granulomas in both patients, and the diagnosis was confirmed by either hepatic biopsy or chest X-ray findings. In conclusion, thyroid involvement should be suspected in sarcoidosis patients who present with cold nodules in the thyroid. Furthermore, if noncaseating granulomas are observed in thyroid specimens after a thyroidectomy in an otherwise healthy person, the patient should be evaluated further for sarcoidosis.
