ABSTRACT
In recent years throughout Korea, the use of ultrasound-guided core needle biopsy (CNB) has become common for the preoperative diagnosis of thyroid nodules. However, there is no consensus on the pathology reporting system for thyroid CNB. The Korean Endocrine Pathology Thyroid Core Needle Biopsy Study Group held a conference on thyroid CNB pathology and developed guidelines through contributions from the participants. This article discusses the outcome of the discussions that led to a consensus on the pathology reporting of thyroid CNB.

Core needle biopsy findings of a follicular neoplasm with a macrofollicular growth pattern. The images in the left column and the right column show the core needle biopsy specimen and the resected specimen, respectively. (A) The ultrasound image shows a well-circumscribed, isoechoic, ovoid nodule with a peripheral hypoechoic rim. A focal cystic change is present. (B) The surgical specimen exhibits a thick fibrotic capsule surrounding the nodule. (C) The core needle biopsy shows a macrofollicular proliferative lesion with a fibrous capsule (arrows). (E) The high-power view of the biopsy specimen shows benign-appearing follicular cells. The typical ultrasound features and thick fibrous capsule can lead to a diagnosis of follicular neoplasm, even in a macrofollicular lesion. The microscopic examination of the surgical specimen shows that the tumor is well encapsulated (D) and capsular invasion is minimal (F).

The microscopic examination of the surgical specimen shows that the tumor is well encapsulated (D) and capsular invasion is minimal (F).

Mentions: FNAC specimens of macrofollicular lesions are usually diagnosed as benign. However, when ultrasound images show the typical features of a follicular neoplasm and the CNB specimen microscopically shows a fibrous capsule, then the CNB specimen can be diagnosed as a follicular neoplasm, even in a macrofollicular lesion (Fig. 3). However, in surgical pathologies, most participants agreed that category III is appropriate in a macrofollicular proliferative lesion with a definite fibrous capsule (Fig. 3).
