A Rare Case of Polymyositis with Autoimmune Subclinical Hypothyroidism.

Hypothyroidism is commonly associated with myopathy. Subclinical hypothyroidism usually presents with vague complaints. Association of autoimmune hypothyroidism with autoimmune polymyositis is known but rare. We diagnosed a patient of polymyositis which also had thyroid dysfunction. Both the conditions were found to be of immunological aetiology with presence of abnormal autoimmune markers in patient's serum. Patient was treated with steroid therapy and analgesic and he responded well with complete recovery of polymyositis. He was kept under observation for subclinical hypothyroidism.
