التهاب الغدة الدرقية
As with other thyroid lesions, thyroid lymphoma affects predominantly females over 70 years of age with a history of Hashimoto's thyroiditis. Thus, Hashimoto's thyroiditis is considered a risk factor for thyroid lymphoma development. Thyroid lymphoma manifests as a rapidly enlarging neck mass which may compress the nearby trachea thereby causing narrowing or obstruction of the airway resulting in breathing difficulties or even respiratory failure. On physical examination, affected people typically exhibit a firm thyroid gland and enlarged lymph nodes.
