(MedPage Today) -- Case Findings: A 60-year-old woman presents with a new non-pruritic rash and muscle weakness. She reports difficulty carrying her groceries and getting up from the couch. A physical examination reveals an erythematous rash on her face, back, and neck, and violaceous papules on her eyelids and the joints of her fingers. Laboratory tests reveal positive antinuclear antibodies and an elevated serum creatinine kinase. This condition is associated with an increased risk of malignancy including renal cell carcinoma, leukemia, thyroid cancer, and ovarian cancer. What is your diagnosis?
