An 84-year-old Caucasian woman presented to our clinic with a diffuse erythematous skin eruption associated with fever and fatigue. The patient has a two-month-old diagnosis of cortico-resistant bullous pemphigoid for which a treatment with dapsone was started one month earlier. Clinical examination confirmed an extended erythematous skin eruption over the trunk and limbs (Fig. 1). Oxygen saturation was measured at 84% with normal lung auscultation. Further clinical examination was normal.
