Abstract
We report a case of a solitary plasmacytoma arising from a thyroid with longstanding Hashimoto's disease, and diagnosed by fine-needle aspiration cytology. Serum protein electrophoresis revealed an M-spike in the gamma-globulin region due to monoclonal IgG-lambda immunoglobulin. The thyroid tumor was treated with near-total thyroidectomy and irradiation, and the patient was well 6 years after surgery without evidence of multiple myeloma. The serum M-spike disappeared after the tumor resection and radiation therapy. Plasma cell lesions of the thyroid reported in the world literature are extensively reviewed. Solitary plasmacytomas occur most commonly in patients with Hashimoto's disease, and must be distinguished from plasma cell granulomas and involvement of the thyroid in multiple myeloma. Plasmacytomas should be considered in the differential diagnosis of a rapidly enlarging thyroid mass in a patient with known Hashimoto's disease.
