Plasmacytoma and follicular lymphoma in a case of Hashimoto's thyroiditis

Histopathology
K AozasaT Yonezawa

Abstract

Monoclonal gammopathy (IgG, lambda) in a 37-year-old man with Hashimoto's thyroiditis, was markedly decreased after thyroidectomy. Histological examination of the thyroid showed large lymphoid follicles surrounded by a massive proliferation of plasma cells. Immunological studies revealed that interfollicular plasma cells stained monotypically for lambda chain, findings in keeping with a diagnosis of plasmacytoma of the thyroid. In addition, there was kappa monotypic staining of the lymphoid follicles and absence of tangible body macrophages, indicating the presence of a follicular lymphoma derived from a separate cell line from the plasmacytoma.

Autoimmune Thyroiditis

Autoimmune thyroiditis is an inflammatory disease of thyroid gland due to autoimmune responses leading to lymphocytic infiltration of the gland. It is characterized by the presence of circulating thyroid antigen-specific T-cells and thyroid autoantibodies. Discover the latest research on autoimmune thyroiditis here.
