• A 39-year-old man with systemic lupus erythematosus (SLE) experienced three episodes of acute orbital inflammation, a primary feature of each being a markedly enlarged extraocular muscle (myositis). The muscles of the upper trunk were concomitantly inflamed, and fullthickness skin and muscle biopsy specimens demonstrated an inflammatory myositis. The case demonstrates that orbital proptosis and extraocular myositis can be features of SLE.
