Study note

Hashimoto’s chronic lymphocytic thyroiditis

THE CONTEXT
Hashimoto’s disease is a common autoimmune thyroiditis that may present with goitre or thyroid failure.

Clinical presentation and antibodies

•
Raised titres of thyroid antibodies usually accompany the condition.
•
The goitre may be diffuse or nodular and can have a characteristic bosselated feel, meaning multiple small protuberances.
•
Patients may present with established or subclinical thyroid failure. Diagnosis often follows investigation of a discrete thyroid swelling.

Histology and end stage

•
Features of chronic lymphocytic focal thyroiditis are commonly found histologically alongside other thyroid diseases, notably toxic goitre.
•
Primary myxoedema without detectable thyroid enlargement represents the end stage of the pathological process.
