Abstract
Toxic epidermal necrolysis (TEN) is a life-threatening, blistering dermatitis. It is characterized by fever and the development of mucocutaneous lesions, which lead to necrosis and sloughing of the epidermis. It is commonly triggered by medications and infections. We present the case of a 75-year-old male who presented to the hospital with a fever and widespread exfoliating skin rash involving 41% of his body surface area (BSA). He has a past medical history of gout, hypertension, asthma, and depression. He was recently started on allopurinol by his general practitioner (GP) for hyperuricemia. The condition also involved oral, eye, and pharynx mucosae. He was diagnosed with toxic epidermal necrolysis and was managed with intravenous (IV) hydrocortisone, steroid and antibiotic eye drops, and steroid and antibiotic topical creams. Due to the weak available evidence supporting the use of ciclosporin and intravenous immunoglobulins, this patient was managed with steroid use only. His rash initially worsened, but ultimately, he made a full recovery without any sequelae. The patient was reviewed in the dermatology clinic four weeks post-discharge, and he did not have any residual disease.
