  (E) She has dennatomyositis, a form of inflammatory
myopathy in which capillaries are the primary target for
antibody and complement-mediated injury. Anti-Jo-1 anti-
bodies, although not present in most cases, are quite spe-
cific for inflammatory myopathies. The perivascular and
perimysial inflammatory infiltrates result in peripheral mus-
cle fascicular myocyte necrosis. The process is mediated by
CD4+ cells and B cells. The heliotrope rash is a character-
istic feature of dermatomyositis. Anti-double-stranded
DNA is specific for SLE, in which there can without significant inflammation or necrosis. Rheumatoid arthritis is accompanied by inflammatory destruction of
joints, not muscle, although muscle may atrophy secondary
to diminished movement The anti-Ul-ribonucleoprotein
antibodies suggest a diagnosis of mixed connective tissue
disease, a condition that can overlap with polymyositis.
Anti-histone antibodies are associated with drug-induced
