The accuracy of fine-needle aspiration (FNA) cytologic diagnosis of nonpalpable breast lesions and the prevalence of neoplasm occurring in areas unrelated to the radiologic abnormality were studied. Template- guided FNA cytologic examination was performed in 101 surgically excised breast specimens. The exact area of the mammographic abnormality was aspirated with radiographic control. Despite accurate placement of the needle for aspiration, seven of 101 aspirates (7%) yielded insufficient cytologic material. Ninety-four of the 101 aspirates (93%) were adequate for diagnosis. The cytologic diagnosis was benign in 58 (62%), atypical in seven (7%), suspicious for malignancy in four (4%), and malignant in 25 (27%). All cases diagnosed as suspicious or malignant and five of 58 cases diagnosed as benign at cytologic examination proved to be malignant at histologic examination. In three of these five the malignancy was in the area of the radiologic abnormality; in two it was not. FNA cytologic examination can be helpful in evaluating nonpalpable breast lesions, but it is not as accurate as histologic examination of surgically excised lesions.
