Russell's sign - anorexia nervosa

Russell’s sign, i.e., the development of calluses over the dorsum of the dominant hand as a result of repeated friction against the front teeth during self-induced emesis, is the most pathognomonic skin sign in anorexia nervosa. Russell’s sign is seen in 67% of patients with the purging subtype of anorexia nervosa.
