Abstract

Fine needle aspiration cytology (FNAC) is generally considered a safe, sensitive, and specific diagnostic tool and is widely used for various clinical indications. However, some authors have raised concerns regarding the possibility of tumor cell seeding along the needle track. We present to our knowledge the first case of tumor seeding after FNAC of a benign parotid tumor. This is followed by a review of the literature on tumor seeding after aspiration with fine needles of 20 gauge and smaller and the implications for clinical practice.
