We studied the hormonal secretion of a human mixed follicular and medullary carcinoma. Thyroglobulin (Tg) secretion, especially by large cells and sometimes by small ones, was visualized with immunoenzymatic staining. Calcitonin (CT) was produced by small spindle-shaped cells. Moreover, immunofluorescence double staining performed on the resected thyroid(More)
