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 biopsies of fibrotic nodules. The right column images represent the high-power views of the lesional area in the left column images. (A) The specimen consists of an acellular fibrotic lesion and adjacent normal parenchyma. (B) The fibrotic area contains no follicular cells, but contains a few lymphocytes and stromal cells. This lesion is classified in the nondiagnostic category. (C) The specimen shows a paucicellular structure with marked fibrosis and calcification. (D) Scattered atypical cells with suspicious morphological features of papillary carcinoma are embedded in the fibrosis. This lesion contains suspicious follicular cells and should therefore be diagnosed as suspicious for malignancy or as a malignancy, depending on the degree of nuclear atypia. (E) The specimen shows marked fibrosis and calcification. (F) The high-power view of the lesion shows relatively numerous benign-appearing follicular cells. This lesion can be diagnosed as a benign follicular nodule.

Mentions: Most participants in the conferences agreed that a sample composed primarily of an acellular/paucicellular fibrotic nodule should be considered nondiagnostic if it did not contain any atypical cells (Fig. 1). However, a categorical diagnosis should be rendered, irrespective of the number of follicular cells, if a sample contains atypical cells (Fig. 1).
