The nodular goiters are histologically represented by two different types of nodules: the colloid nodules, related with accumulation of the colloid within the follicles and the hyperplastic (adenomatoid) nodules, characterized by a hyperplasia of the follicular cells. Adenomatoid means that the nodules looked similar to a non-cancerous type of growth called a follicular adenoma. Dr. Addagada Rao answered.

These nodules are characterized by a predominance of macrofollicles such as the one shown here. A thyroid adenoma is distinguished from a multinodular goiter of the thyroid in that an adenoma is typically solitary, and is a neoplasm resulting from a genetic mutation (or other genetic abnormality) in a single precursor cell. 2018 Jul-Aug;19(4):632-655. doi: 10.3348/kjr.2018.19.4.632.

Stratification of cytologic diagnoses of follicular thyroid lesions into different subcategories with various probabilities of malignancy allows more accurate estimation of malignancy risk and individualized patient treatment, when deciding between immediate operation and close follow-ups with repeat FNA.

Fine needle aspiration (FNA) is an economical procedure that allows prompt evaluation of a thyroidal mass. Although they may grow large, and there may be more than one, they are not malignant and they will not spread beyond the thyroid gland.

Careers. Thyroid biopsy is the most commonly used method to distinguish cancerous from non-cancerous thyroid nodules. The cytopathologist should obtain the aspirates or else should accompany the clinician performing the aspirations. Optical biopsy of head and neck cancer using hyperspectral imaging and convolutional neural networks. The diagnosis of follicular neoplasms and some cellular adenomatoid nodules remains problematical. Please enable it to take advantage of the complete set of features! In contrast, a multinodular goiter is usually thought to result from a hyperplastic response of the entire thyroid gland to a stimulus, such as iodine deficiency. The aims of this study were to determine the diagnostic utility of FNAC performed in our institution, assess the cytomorphologic features that contribute to diagnostic errors and propose improvement measures.
