Introduction:
Hashimoto’s thyroiditis (HT) is autoimmune thyroid disease and one of the common causes of primary hypothyroidism [1]. It can be responsible or associated with several rheumatic manifestations [2].
Rheumatic manifestations, such as arthritis and non-specific musculoskeletal symptoms, can reveal hypothyroidism. These manifestations can be related to thyroid dysfunction, connective tissue diseases associated with HT, or thyroid autoimmunity [3].
We report the case of an acute polyarthritis revealing primary hypothyroidism caused by Hashimoto’s thyroiditis.
We emphasize clinical, biological, and management of this condition.
