A young woman with abrupt changes in skin and mucosa

Cutaneous and mucosal changes due to adverse drug effects are relatively common in clinical daily practice; however, the etiology often follows unsuspected, undetermined and underreported. More severe lesions like the Stevens-Johnson syndrome should be early recognized and treated. As the entity is potentially lethal if not properly managed, and diagnosis is imminently clinical, the characteristic images might contribute to enhance the suspicion index about this syndrome.
