Overview

In 1974, the international committee of thyroid pathologists published the first WHO histological classification of thyroid tumors which had served as a basis for various clinical, pathological, and epidemiological studies. Goiter may also be classified according to various classification methods based on etiological, epidemiological, anatomical, pathological, functional and morphological factors.
