A case of Stevens-Johnson syndrome triggered by Mycoplasma infection.

Stevens-Johnson syndrome (SJS) is a rare, potentially life-threatening mucocutaneous disorder, which is often triggered by infections such as Mycoplasma pneumoniae. This report describes a 19-year-old woman who initially presented with oral erosions and painful blisters, along with fever and cough. Oral lesions preceded skin and ocular involvement, and tests confirmed Mycoplasma-associated SJS. She responded to steroid pulse therapy but relapsed at 3 months and was then successfully treated. Oral manifestations may be early SJS indicators; thus, prompt recognition and interdisciplinary care by oral health professionals are vital for improving clinical outcomes.
