[A case of primary thyroid lymphoma with Hashimoto thyroiditis].

Postoperative course was complicated by the tumor reoccurence presenting as invasion of the larynx with a critical narrowing of the lumen of the larynx. With chemotherapy complete remission has been achieved. This case illustrates common aetiology of the thyroid lymphoma of MALT type and Hashimoto thyroiditis.
