Necrotic smear back ground may be seen in high risk thyroid carcinomas and acute infarction of thyroid nodules. Acute infarction in thyroid nodules may occur either sporadic or after fine needle aspiration (FNA) cytology. It causes diagnostic problems, 1) making histological confirmation difficult, and/or 2) may have difficulties in obtaining diagnostic materials.
