Systemic Lupus Erythematosus and Dermatomyositis Overlap Syndrome: Diagnostic Challenges and Management Insights

We present the case of a 27-year-old female patient who was initially diagnosed with dermatomyositis and later found to have an overlap with systemic lupus erythematosus (SLE). Despite extensive treatment with immunosuppressive medication, the patient experienced multiple deteriorations and treatment-related complications with waxing and waning improvement. This case aims to underscore the challenges involved in diagnosing and managing overlap syndromes and highlights the importance of comprehensive diagnostic workup and multidisciplinary care.
