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.
