Abstract
Imaging-driven detection of thyroid nodules has expanded the role of fine-needle aspiration (FNA) while demanding integration of molecular data into routine cytologic assessment. We present four illustrative cases spanning the contemporary diagnostic spectrum: (1) an Atypia of Undetermined Significance (AUS) nodule with dual low-level PTEN mutations managed by active surveillance; (2) an oncocytic follicular neoplasm upgraded to total thyroidectomy by concurrent HRAS and TERT promoter mutations; (3) an oncocytic subtype poorly differentiated thyroid carcinoma (O-PDTC) highlighting subtle high-grade cytologic cues and a distinct genomic profile; and (4) a pediatric poorly differentiated carcinoma harboring a DICER1 hotspot mutation, underscoring age-specific biology and the need for genetic consideration. These cases emphasize that morphology remains foundational, but mutation context, single versus co-alterations, allelic burden, and patient age ultimately direct management. Harmonized reporting that clearly conveys molecular findings is essential to translate limited cytology material into precise, patient-specific care.
期刊介绍:
Diagnostic Cytopathology is intended to provide a forum for the exchange of information in the field of cytopathology, with special emphasis on the practical, clinical aspects of the discipline. The editors invite original scientific articles, as well as special review articles, feature articles, and letters to the editor, from laboratory professionals engaged in the practice of cytopathology. Manuscripts are accepted for publication on the basis of scientific merit, practical significance, and suitability for publication in a journal dedicated to this discipline. Original articles can be considered only with the understanding that they have never been published before and that they have not been submitted for simultaneous review to another publication.
