We report the case of a patient with anti-MDA5 Ab-positive clinically amyopathic dermatomyositis (CADM) with the recurrence of interstitial lung disease (ILD) after 7 years of remission. There has been no case report of an anti-MDA5 Ab-positive DM patient with the recurrence of ILD after 7 years of long-Term remission. Patient concerns: A 70-year-old Japanese woman was diagnosed with anti-MDA5 Ab-positive CADM and ILD. After achieving 7 years long-Term remission, she was admitted to our department with erythema on the fingers and interstitial pneumonia. Her anti-MDA5 Ab titer was elevated. Diagnoses: We diagnosed recurrent CADM complicated with ILD. Interventions: We successfully treated her with 1,000 mg of methyl-prednisolone pulse and intravenous cyclophosphamide therapy followed by prednisolone 50 mg/day and an increase of cyclosporine. Outcomes: After that treatment, the patient's skin symptoms and interstitial pneumonia were relieved. All laboratory investigations such as ferritin, the serum markers of interstitial pneumonia (i.e., SP-A, SP-D), and the titer of anti-MDA5 Ab showed signs of improvement. Lessons: Her case suggests that careful physical examinations and monitoring the serum markers are important even after long-Term remission is achieved., Medicine, 97(26), art. no. e11024; 2018}, title = {Recurrence of anti-MDA5 antibody-positive clinically amyopathic dermatomyositis after long-term remission}, volume = {97}, year = {2018} }
