Primary thyroid gland lymphomas are uncommon tumours that occur in the setting of lymphocytic thyroiditis or Hashimoto's disease in almost all cases. Rarely these tumours show extensive plasmacytic differentiation. In these conditions, a distinction between an inflammatory thyroid infiltrate and extramedullary plasmacytoma may be extremely difficult and precise criteria and ...
