My watch list  


Dermatophagia (sufferers can be called wolf-biters)[1] is a form of neurodermatosis wherein a sufferer habitually bites their skin.[1][2] It often takes the form of chewing on the fingers,[3] and when left unchecked, can lead to discoloration and damage.

Additional recommended knowledge


 Sufferers of dermatophagia often chew their skin out of habit or compulsion,[1][2] and can do so on a variety of places on their body.[2] Commonly, it seems to manifest in the fingers, where the skin around fingernails and surrounding joints get the brunt of the damage.[3] If the behavior is left unchecked for an extended period, callouses may start to develop where most the biting is done.[2]

Skin chewing can be bolstered by times of apprehension and other unpleasant events.[2] Another disorder, known as dermatillomania, the act of picking at one's skin, can sometimes accompany dermatophagia.
