Hashimoto Thyroiditis & Thyroid Lymphomas: Microscopically, Hashimoto thyroiditis shows marked damage to the thyroid parenchyma with lymphocytic infiltration of the gland and formation of large lymphoid follicles with well-demarcated germinal centers. The thyroid follicles are small and atrophic and the follicular cells show prominent oxyphilic (Hurthle cell) change. Foci of squamous metaplasia and fibrosis may be present.
