Stevens-Johnson Syndrome (SJS) As the Initial Presentation in a Patient With a New Diagnosis of HIV.

A woman in her 40s presented to the emergency department with a diffuse rash consistent with Stevens-Johnson syndrome (SJS). There was no identifiable inciting factor. However, she was newly diagnosed with human immunodeficiency virus (HIV) during that same hospital admission. The leading theory for why she developed SJS given her lack of classic precipitating factors is an immune dysregulation as a result of HIV. Most cases of SJS/toxic epidermal necrolysis (TEN) in patients with HIV are related to highly active antiretroviral therapy and prophylaxis with trimethoprim-sulfamethoxazole. There is a lack of literature regarding SJS as the initial presentation of HIV without known underlying etiology or inciting factors.
