According to the literature, the percentage of false negative results (FN-FNA) is less than 1.5%, in tertiary health care centers.In this study we describe the cases reported in this Hospital, between 2014 and 2016, of benign cytology, histologically characterized as malignant. All pathologic specimens were reviewed.<p cl...
