Amyloid goiter (AG) (primary or secondary) is extremely rare. An abdominal fat pad core needle biopsy (CNB) is the diagnostic gold standard for secondary amyloidosis. Although CNB is useful to detect amyloid infiltration of a specific organ, fine‐needle aspiration (FNA) is proven to be the best diagnostic method for thyroid disorders. Guidelines recommend an ultrasound‐guided FNA (US‐FNA) whenever possible. This procedure is usually performed by various interventional specialists, including pathologists, who perform the procedure in addition to validating the adequacy of the sample. We report a rare case of AG diagnosed using US‐FNA performed by a pathologist in a 39‐year‐old patient with systemic amyloidosis. US‐FNA performed by pathologists is a proven, less‐invasive, and cost‐effective tool that ensures acquisition of adequate specimens and reduces nondiagnostic rates of this procedure to ensure timely cytological diagnosis.
