Unmasking the Complexity: Primary Systemic Lupus Erythematosus Coexisting with Drug-Induced Lupus – A Unique Case Report"

Systemic lupus erythematous (SLE) is a chronic autoimmune disease that affects multiple systems in the body, and it follows a relapsing-remitting course. Certain medications can trigger SLE in individuals who are genetically susceptible to the condition, leading to drug-induced lupus (DIL). Currently, over 100 drugs are suspected to induce DIL, and the list of drugs continues to grow as new drugs arise. In this case, we present the case of a 50-year-old patient who had primary SLE and subsequently developed drug-induced SLE after receiving ATT treatment. Previous literature has shown that the risk of drug-induced lupus increases with age, and our patient's age supports this finding. Therefore, the patient was admitted and treated as a case of primary SLE with Superimposed Drug-Induced SLE.
