RESUMO
Stevens-Johnson syndrome (SJS) is a life-threatening acute and fatal dermatological disease. It can present with many variations and rapidly worsens in a short period of time. Early diagnosis and management play an important role in stopping SJS from progression. Various drugs such as antibiotics, anticonvulsants and non-steroidal anti-inflammatory drugs can trigger the disease as an adverse effect. Oral and dental manifestation of SJS is uncommon. However, dentists should be clinically oriented towards signs and symptoms of the disease, both oral and systemic. We present a case of a 37-year-old male with no past medical history who presented to the dental emergency clinic complaining of dysphagia and burning sensation in the mouth. On oral examination, oral rash and blisters were observed. In addition, a bilateral forearm erythematous, non-blanching painful rash with some blisters was found after antibiotic administration three days earlier. The antibiotic was stopped and the patient was started on topical betamethasone for 14 days, topical chlorhexidine for 10 days, and oral nystatin suspension 100,000 units. A complete resolution of the oral and systemic manifestation was seen without the need for hospital admission.
