| Abstract: | Morphometry was applied to smears of fine needle aspirates from 26 oxyphilic thyroid neoplasms. Thirteen tumors were considered benign as judged from histologic findings and clinical follow-up for 2 to 20 years after the operation. Thirteen tumors were considered malignant histologically; four of these had proven metastases. In each case the mean and standard deviation of the projected nuclear area were calculated from 200 nuclei in the smear. Our results indicate that morphometric estimation of mean nuclear size and/or degree of anisokaryosis is of no practical value in distinguishing between benign and malignant thyroid neoplasms of the oxyphilic type. |
