An Interesting Case of Anti-Small Ubiquitin-Like Modifier-Activating Enzyme (SAE) Antibody-Positive Dermatomyositis.

Dermatomyositis (DM) is a heterogeneous autoimmune disease characterized by inflammatory involvement of the skin and muscles. Anti-small ubiquitin-like modifier activating enzyme (SAE) antibodies define a rare clinical subtype of DM, often associated with prominent cutaneous findings and systemic features such as dysphagia. This report presents the case of a 45-year-old male with steroid-refractory, anti-SAE-positive DM, highlighting the diagnostic and therapeutic challenges of this condition and underscoring the importance of early recognition and personalized management.
