Erythema Multiforme Versus Stevens-Johnson Syndrome/Toxic Epidermal Necrolysis: Subtle Difference in Presentation, Major Difference in Management.

Erythema multiforme and Stevens-Johnson syndrome/toxic epidermal necrolysis are immune-mediated epidermal conditions with variable clinical presentations. Although their clinical presentations often overlap, they have distinct etiologies and potential outcomes, which necessitate specific management strategies. This case is presented to highlight the subtle differences and review management given that Stevens-Johnson syndrome/toxic epidermal necrolysis can rapidly become life-threatening. The need for astute diagnostic work-up and accuracy is magnified in the military setting given operations in austere environments and availability of medical and medical evacuation resources. Herein, we present a less common case of bullous erythema-multiforme, the diagnostic approach, and clinical differential with special attention to the importance of the military physician.
