Fig. 6. — Examples of follicular neoplasm (category IV) in thyroid core needle biopsy. (A) The low-power view shows a follicular proliferative lesion with a fibrous capsule (arrows). (B) The high-power view of Fig. 6A reveals microfollicular growth pattern and no nuclear atypia. This lesion can be interpreted as follicular neoplasm, conventional type (category IVa). (C) The specimen shows a follicular proliferative lesion with a thick fibrous capsule (arrows). (D) The high-power view of Fig. 6B reveals microfollicular growth pattern and follicular cells with nuclear atypia, suggesting follicular neoplasm with nuclear atypia (category IVb). (E, F) Another example of follicular neoplasm with nuclear atypia (category IVb), in which, the lesion shows a fibrous capsule (arrows) nuclear atypia in focal areas (F).
