Dermatophagia

Dermatophagia is a type of impulse control disorder and obsessive–compulsive disorder wherein sufferers compulsively bite their own skin. Sufferers typically bite the skin around the nails, leading to bleeding and discoloration over time. Some may consume the flesh during an episode.〔
Contemporary research suggests a link between impulse control disorders and obsessive–compulsive disorders, and this may be addressed in the ''DSM-5'', due for publication in May 2013.〔(【引用サイトリンク】title=DSM-5: The Future of Psychiatric Diagnosis )〕 Further information on differentiation between OCD, other anxiety disorders, and dermatophagia and other impulse-control disorders can be found in the ''DSM-IV TR''.
==Behavior==
Dermatophagia sufferers chew their skin out of compulsion, and can do so on a variety of places on their body.〔 Sufferers typically chew the skin surrounding their fingernails and joints. They also chew on the inside of their mouth, cheeks, and/or lips, causing blisters in and outside of the mouth. If the behavior is left unchecked for an extended period, calluses may start to develop where most of the biting is done.〔
Skin chewing can be bolstered by times of apprehension and other unpleasant events.〔 Blisters in particular can cause a feeling of desire to pull or bite off the affected skin (since the skin is dead, thus easily pulled off), which could be detrimental, causing infection. Another disorder, known as dermatillomania, the act of picking at one's skin, can sometimes accompany dermatophagia. People who suffer from dermatophagia can also be prone to infection as when they bite their fingers so frequently, they make themselves vulnerable to bacteria seeping in and causing infection. Dermatophagia can be considered a "sister" disorder to trichophagia, which involves compulsively biting and eating one's hair.
