Abstract
Dermatomyositis (DM) is an autoimmune idiopathic inflammatory myopathy with characteristic dermatologic manifestations. Myositis-specific autoantibodies (MSAs) delineate DM subtypes and their prognoses. Uncommonly, patients present with distinct clinical features of DM, including photosensitive dermatitis, heliotrope rash, Gottron's papules, and nailfold changes; however, their autoimmune serology is negative for expected MSAs. Herein, we describe two unconventional cases of seronegative, amyopathic MDA5-DM and offer potential explanations, including fluctuating antibody levels, non-MSA pathophysiology, and limitations in current immunoassays.
期刊介绍：
SAGE Open Medical Case Reports (indexed in PubMed Central) is a peer reviewed, open access journal. It aims to provide a publication home for short case reports and case series, which often do not find a place in traditional primary research journals, but provide key insights into real medical cases that are essential for physicians, and may ultimately help to improve patient outcomes. SAGE Open Medical Case Reports does not limit content due to page budgets or thematic significance. Papers are subject to rigorous peer review and are selected on the basis of whether the research is sound and deserves publication. By virtue of not restricting papers to a narrow discipline, SAGE Open Medical Case Reports facilitates the discovery of the connections between papers, whether within or between disciplines. Case reports can span the full spectrum of medicine across the health sciences in the broadest sense, including: Allergy/Immunology Anaesthesia/Pain Cardiovascular Critical Care/ Emergency Medicine Dentistry Dermatology Diabetes/Endocrinology Epidemiology/Public Health Gastroenterology/Hepatology Geriatrics/Gerontology Haematology Infectious Diseases Mental Health/Psychiatry Nephrology Neurology Nursing Obstetrics/Gynaecology Oncology Ophthalmology Orthopaedics/Rehabilitation/Occupational Therapy Otolaryngology Palliative Medicine Pathology Pharmacoeconomics/health economics Pharmacoepidemiology/Drug safety Psychopharmacology Radiology Respiratory Medicine Rheumatology/ Clinical Immunology Sports Medicine Surgery Toxicology Urology Women''s Health.
