Oncocytic lesions of the thyroid are a heterogeneous group encompassing nonneoplastic and neoplastic entities ranging from benign to malignant and have traditionally been classified as separate entities in thyroid pathology. To illustrate the diversity of these thyroid lesions, we describe three cases of fine needle aspiration biopsies (FNAB) diagnosed as Bethesda Category IV: Follicular neoplasm, oncocytic type, under the 2017 Bethesda System for Reporting Thyroid Cytopathology (TBSRTC), with ThyroSeq v3 molecular testing and subsequent surgical excision.

甲状腺细针抽吸活检诊断为具有嗜酸细胞特征的滤泡性肿瘤的病例系列

甲状腺的嗜酸细胞病变是一个异质组，包括从良性到恶性的非肿瘤性和肿瘤性实体，传统上在甲状腺病理学中被分类为单独的实体。为了说明这些甲状腺病变的多样性，我们描述了根据 2017 年贝塞斯达甲状腺细胞病理学报告系统 (TBSRTC) 诊断为贝塞斯达 IV 类的细针抽吸活检 (FNAB) 病例：滤泡性肿瘤，嗜酸细胞型，采用 ThyroSeq v3 分子测试和随后的手术切除。
