Myositis of small foot muscles.
Idiopathic focal myositis is a rare clinical entity and is mostly localized in the neck and thigh muscles presenting as a pseudotumor. We describe a 49-year-old patient with inflammation restricted to the small muscles of one forefoot. Systemic disease was not present and progression to polymyositis did not occur within 2 years of follow-up. The myositis improved promptly after initiation of immunosuppressive therapy with corticosteroids and azathioprine. This unusual location of focal myositis has not been previously reported.
