Those with dermatophagia typically chew the skin surrounding their fingernails and joints. They also chew on the bottom of their feet/toes, 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 ...
Signs and symptoms Compulsive picking of the knuckles (via mouth) illustrating potentially temporary disfiguration of the distal and proximal joints of the middle and little fingers. The fingers have been compulsively picked and chewed in someone with excoriation disorder and dermatophagia.
Russell's sign, named after British psychiatrist Gerald Russell, is a sign [1] defined as calluses on the knuckles [2] or back of the hand due to repeated self-induced vomiting over long periods of time.
Symptoms. Common symptoms in humans include: Nail biting; Pulling hair; Chewing fingers (in extreme cases, leading to amputation) Possible causes. This section will focus on the causes for autophagia in humans. There is no single primary cause for autophagia.
Nail biting, also known as onychophagy or onychophagia, is an oral compulsive habit of biting one's fingernails. It is sometimes described as a parafunctional activity, the common use of the mouth for an activity other than speaking, eating, or drinking.
Trichophagia is a form of disordered eating in which persons with the disorder suck on, chew, swallow, or otherwise eat hair. The term is derived from ancient Greek θρίξ, thrix ("hair") and φαγεῖν, phagein ("to eat").
Diagnosis is less easy in the early stages, when the three features are not yet obvious. Signs of self-injurious behavior (SIB), results of pedigree analysis and novel molecular biology with genetic testing (called as Diagnostic triad for LNS), often confirms the diagnosis.
It is not the same as onychophagia, where the nails are bitten or chewed, or dermatillomania, where skin is bitten or scratched. Onychotillomania can be categorized as a body-focused repetitive behavior in the DSM-5 and is a form of skin picking, also known as excorciation disorder .
Coffin–Lowry patients may be affected by chewing and swallowing difficulties, for which there are diagnostic assessments. Among these are the Videofluoroscopic Swallowing Evaluation (VFSE), the Karaduman Chewing Performance Scale, and the Penetration Aspiration Scale (PAS) which is used to evaluate accidental aspiration of food particles.

The main form of diagnosis is presumptive, if the person has the usual triad of preaxial polydactyly with cutaneous syndactyly of at least one limb, macrocephaly, and hypertelorism. However, a definitive diagnosis can be made if there is a phenotype that is caused by a Gcps and a Gli3 gene mutation.
