Q: passage: Dermatophagia (from Ancient Greek δέρμα - skin - and φαγεία - eating) is a compulsion disorder of gnawing, biting or eating one's own skin, most commonly at the fingers. People with dermatophagia typically bite the skin around the nails, leading to bleeding and discoloration over time. Some people also bite on their skin on their finger knuckles which can lead to pain and bleeding just by moving their fingers. Some usually 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, published in May 2013. Further information on OCD, other anxiety disorders, and dermatophagia and other impulse-control disorders can be found in the DSM-IV TR.
 question: is there a disorder for eating your own skin?

Yes
