Abstract:
A 74-year-old woman with a primary thyroid plasmacytoma was studied. Clinical signs included a mass in the neck, as well as muscle and skin involvement due to dermatomyositis. In her serum a monoclonal IgG lambda was present. Immunohistochemistry showed an intracellular monoclonal IgG lambda component. After thyroid surgery and radiation, clinical improvement and fall of M protein were noted. On longterm followup, only palmar fasciitis persisted.
