The first step in the management of patients presenting with thyroid nodules is an accurate triage of those who should be referred to surgery [15]. In spite of the advances in ultrasound (US) imaging [68] and the promising results of molecular analysis [916], this basic step still strongly relies on cytology [3]. Among the acronyms used to indicate the sampling technique for thyroid cytology (FNA, FNAB, FNAC, FNC), fine-needle aspiration (FNA) is the most frequently adopted and it will be employed in this document. When the cytologic specimen is obtained without aspiration the term FNC (fine-needle cytology) may be used [2].

In the recent years, a variety of four- to six-tiered reporting schemes for thyroid cytology have been proposed by different societies and institutions, with the aim of improving the communication between cytopathologists and clinicians [17].
