Abstract

Primary thyroid lymphomas constitute of up to 5% of all thyroid malignancies. Recently, mucosa-associated lymphoid tissue (MALT) lymphoma are relatively recognized as a B cell subset of non-Hodgkin's lymphoma. MALT-lymphomas are thought to develop from acquired lymphocytic tissue during the course of a chronic inflammatory or autoimmune process. In the thyroid , which is normally devoid of lymphocytic tissue, chronic autoimmune thyroiditis (Hashimoto's disease) has been associated with an increased risk of lymphoma, including MALT type. The clinical presentations include the enlarging of the neck mass, dysphagia, hoarsenes and choking or cold thyroid nodule. We report a case of MALToma of the thyroid accompanied by Hashimoto's thyroiditis with a review of the literature.
