Planimetric studies on fine needle aspirates from follicular adenoma and follicular carcinoma of the thyroid.
A planimetric study was performed on fine needle aspiration biopsy smears from 21 follicular thyroid adenomas, 13 follicular thyroid carcinomas and 7 nontoxic goiters. The nuclear and the cytoplasmic projected areas were measured in each smear on 50 cells with intact nuclei. The nuclear-cytoplasmic area was calculated. Significant differences in mean nuclear area were found between benign and malignant follicular neoplasms and between neoplastic cells and cells from nontoxic goiter. Planimetry of cells aspirated from follicular neoplasms permitted differentiation between carcinomas and adenomas with a high degree of statistical probability.
