TEN with spots is defined as widespread, irregularly shaped erythematous or purpuric macules with blistering that occurs on all or part of the macule. Blisters become more confluent and result in detachment of the epidermis and erosions on greater than 30% of the body surface area. Mucosal surfaces are usually involved.
