Adenolipoma (thyroid gland)

Adenolipoma of the thyroid gland (also known as a thyrolipoma or a thyroid hamartoma) is a rare, benign fat-containing thyroid lesion. These lesions are usually well encapsulated and are composed of varying degrees of follicular thyroid tissue (thyroid adenoma) and mature adipose tissue; the amount of fat can markedly vary (from 10-90%).

Treatment and prognosis

A large adenolipoma causing airway obstruction should be removed. Surgical excision is curative ⁶. As aforementioned, this lesion is benign and has no malignant potential.
