Riedel's thyroiditis is a rare benign pathology of unclear etiology, characterized by a densely fibrotic inflammatory process involving the thyroid gland and the adjacent neck tissues. This rare form of chronic thyroiditis often leads to clinical evidence of anaplastic thyroid carcinoma or lymphoma. We discuss, based on an observation of an unusual case of Riedel's thyroiditis, the clinical characteristics and management modalities of this rare entity.
