A FNAC Case of Metastatic Cystic Papillary Carcinoma of the Thyroid Simulating Parotid Tumor

One of the authors (NP) received one year subspeciality training in cytopathology abroad (Norwegian Radium Hospital, Oslo). At the same time two radiologists were also trained in interventional procedures. Before we provided the fine needle aspiration it was never applied in our institution. Over 2 years, the number of cases has already exceeded 1000. Except a few ‘false negative’ cases mainly due to non-representative material we have, so far, no ‘false positive’ case. Despite the acceptance of the procedure is gradually increasing, we are very much aware that false diagnosis (especially positive one) can easily create scepticism among our clinical colleagues. It is well reported that aspiration of adequate and representative material as well as accurate interpretation are essential criteria for successful FNAC.
