Medicines often cause serious immune-mediated mucocutaneous reactions including Steven-Johnson Syndrome (SJS) and toxic epidermal necrolysis (TEN). In the acute phase of SJS and TEN, a febrile illness is followed by cutaneous erythema with blister formation, skin and mucous membrane necrosis, and separation of the skin and mucous membranes. The patient swiftly becomes in danger of dying, necessitating immediate medical attention.In this case report, we described a case of Steven-Johnson Syndrome in a 102-year-old female who was receiving palliative care and had stage 5 chronic renal disease. Although the agent that caused SJS in this patient is unknown, the patient was managed with topical medication, bandages for the lesions, and oral antihistamines. Skin biopsy, abdomen ultrasound, and sezary cell test were advised for the patient. Such presentations at that age have not, to our knowledge, been documented before.
