The study was done to evaluate the role of morphometry in various thyroid lesions with cytological and histological correlation. Cytology and histology of 100 cases of non-neoplastic, benign and malignant thyroid lesions were compared, together with the role of morphometric nuclear parameters with the aid of an ocular morphometer attached to the 6x eye-piece of a microscope using a 40x high-dry objective. Analysis of Variance (ANOVA) among definite adenomatoid goitre, suspicious lesions and definite follicular neoplasm as identified by FNAC and between non-neoplastic lesions, follicular neoplasm and other carcinomas in FNAC after histological correlation was highly significant (p<0.0001). ANOVA among nonneoplastic, benign and malignant in histology (p<0.0001) and t-test between Papillary carcinoma and follicular carcinoma in histology (p<0.0028) were also highly significant. Morphometry correlated with cytology and histology proved to be an extremely valuable tool in case of thyroid lesions increasing the sensitivity of FNAC from 59.09% to 82.61%, predictive value of negative test from 87.84% to 93.85%, accuracy rate from 89.66% to 95.24% and decreased the Percentage of false negative from 40.91% to 17.39%.
