Lymphocytic and Hashimoto thyroiditis represent different phases of autoimmune thyroiditis. There is cellular and antibody-mediated (humoral) immune injury to the gland. The initiating factor may be a thyroid-specific defect in suppressor T lymphocytes. The predominant histologic finding is infiltration of the parenchyma by lymphocytes and plasma cells with formation of germinal centers.
