Toxic Epidermal Necrolysis (TEN) is a severe medical condition characterized by the detachment of the skin and mucous membranes. The condition is rare, life-threatening and often caused by the reaction to medication or infection. The opposite of TEN is the healthy and intact epithelium, which lines the internal and external surfaces of the body, protecting it from the environment. Any compromise to this barrier function, like in TEN, can lead to severe infection, fluid and electrolyte imbalances and even death. The antonyms of TEN could include healthy, normal, robust, stable, and unimpaired skin and mucosa, indicating the absence of the disease or the successful recovery from it.
