Synonyms
Adenomatous/adenomatoïd nodule; Hyperplastic nodule; Multinodular goiter
Definition
The term “goiter” refers to any enlargement of the thyroid gland and is considered as a non-neoplastic process, usually benign, essentially due to iodine deficiency, but sometimes of unknown etiology. The term “goiter” includes both either a thyroid gland deformed by numerous nodules of varying sizes or a diffuse enlargement of the gland. 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.
Clinical Features
Incidence
Nodular goiters represent one of the most frequent diseases in the world with a prevalence from 1% to 10%, depending on geographic locations. Goiters are more frequent in mountains than in the low lands and on the sea-side. In the United States, there is an estimated...
