ABSTRACT
Lesions involving adipose tissue and the thyroid gland are usually rare. In the present report, adipose metaplasia is associated with Hashimoto's thyroiditis with nodular hyperplasia and oncocytic adenoma in a 40-years-old female patient, which is one of the first reported cases of this association. The main clinical finding is the diffuse goiter, and the differential diagnosis must be performed to exclude the possibility of malignancies. The treatment is performed through total thyroidectomy. Thus, it is important the physicians be aware of this pathology with a view to a more effective clinical reasoning and to exclude more serious possibilities.
Key words:
metaplasia; lipomatosis; Hashimoto's disease; adenoma; hyperplasia
