It develops through a combination of immune dysregulation, genetic susceptibility, and triggers such as ultraviolet light, medications, or other environmental exposures. In some people it remains confined to the…

In most cases, the bacteria…

Stevens-Johnson syndrome produces a distinctive pattern of symptoms centered on abrupt skin pain, blistering rash, and inflammation of the mucous membranes. The earliest complaints are often flu-like, but the condition quickly moves into a much more specific set of findings: tender red or dusky patches, blisters, erosions, eye irritation, and painful lesions in the mouth…
