Core needle biopsies of malignant thyroid tumors (category VI). (A, B) Diffuse sclerosing variant of papillary carcinoma. (C, D) Poorly differentiated carcinoma shows solid, trabecular, and insular growth patterns and mitosis (arrows) under high-power field. Medullary carcinoma shows typical histologic features under low-power field (E) and high-power field (F). Nuclei of tumor cells are round to oval and carry coarsely granular chromatin. The cytoplasm is finely granular eosinophilic to amphophilic.
