Dermatomyositis is a systemic, autoimmune diseasewith a variety of clinical features that often includemyositis and characteristic cutaneous findings. Asubset of patients with dermatomyositis developcutaneous ulcers, often in the setting of vasculitis orvasculopathy. We present a case of dermatomyositiswith cutaneous ulcers that show perforatingcollagenosis on histopathologic examination.Acquired reactive perforating collagenosistypically occurs in the setting of diabetes mellitus,chronic renal failure, and other pruritic conditions,and this case represents a rare association withdermatomyositis, which may ultimately be helpful inelucidating the pathophysiology of this perforatingdisorder.
