The Stevens-Johnson syndrome (SJS) classically involves a rash, conjunctivitis and mucositis. We describe the case of a young adult male with isolated mucositis and conjunctivitis . Previous rare reports of severe SJS like syndromes without a rash are confined to children, usually with mycoplasma pnemoniae infection.(1) Terminology for this syndrome includes - "Stevens-Johnson Syndrome without skin lesions", or "Atypical Stevens - Johnson Syndrome".(2) This case highlights the importance of maintaining an open mind when a "full house" of clinical features is absent. It also illustrates the use of a rapid electronic literature review as a clinical tool. The importance of updating records when a drug has been cleared of causing harm is highlighted.
