Acute Kidney Injury Following Dermatomyositis.

Renal involvement in patients with inflammatory myopathies, like dermatomyositis, is rare. We present the case of a woman, aged 66 years, who arrived at the hospital with acute renal failure. She had a diffuse erythematous rash, severe muscle weakness and decreased motor capacity. Inflammatory features of the skin/muscle biopsy along with the dramatic improvement in symptomatology upon the intake of steroids pointed towards dermatomyositis. Recognition of this pattern of events, adopting a multidisciplinary approach, early diagnosis and steroid treatment are necessary for better patient outcomes.
