Abstract
The value of fine needle aspiration biopsy (FNAB), which is safe and simple, in diagnosing thyroid nodules has been established. Commonly, specimens obtained by FNAB are classified into 5 groups from Class I to V.In this paper, we attempted to reevaluate the specimens belonging to Class III which were undertermined as malignant even though a presence of atypical cells. Of 147 available cases in a recent 3-year period, 16 cases were classified as Class III, of which 5 were diagnosed as benign and 11 as malignant histologically. In a retrospective reevaluation, eight papillary carcinomas were considered malignant, while three follicular carcinomas were judged to be benign. Thus, the tumor of which specimen is classified as Class III should be served as a surgical candidate for histological comfirmation.
