Corns utvecklas från upprepad gnuggning eller tryck. Corn är ett specifikt område med förtjockad hud, medan callus är mer utspritt. Corns förekommer ofta hos idrottare eller personer med fotproblem som ojämn friktion från skor. De är också vanliga hos äldre, diabetiker och amputerade. Corns ska ses som ett symptom snarare än ett fristående tillstånd.
A corn, also known as a calvus, heloma, or focal intractable plantar hyperkeratosis, is a type of callosity. Corns are uncomfortable, thickened skin lesions that result from repeated mechanical trauma due to friction or pressure forces. In the literature, confusing terminology is often used to call different types of hyperkeratotic skin lesions. Nevertheless, a corn should be distinguished from a callus, which is a more diffuse type of callosity. Thus, a corn is a well-delimited focal area of hyperkeratosis. This condition is often seen in athletes and patients exposed to unequal friction force from footwear or gait problems, including the elderly, patients with diabetes, and amputees. It should be regarded as a symptom rather than an effective disease.

Corn , även känd som clavus, är ett vanligt fottillstånd som ses på kliniker. Det är ett förtjockat hudområde som orsakas av friktion eller tryck, ofta smärtsamt. Det är viktigt att skilja det från förhårdnader eller vårtor. Förhårdnader liknar varandra men saknar den centrala kärnan och är mindre smärtsamma. Behandlingen syftar till att lindra symtomen och förhindra framtida liktornar. Att behandla detta smärtsamma tillstånd kan avsevärt förbättra patienternas liv, särskilt för äldre eller aktiva individer.
A clavus or clavi (plural) is a frequently encountered condition in the out-patient clinic, known colloquially as a corn. It is one of the many hyperkeratotic lesions of the foot and therefore requires differentiation from other etiologies such as calluses or plantar warts. A clavus is a well-demarcated thickened area of the epidermis that has a central core. This skin lesion is most commonly found on the foot and is often painful. A clavus results from repeated friction, pressure, or trauma to a specific area of the foot. A callus is another hyperkeratotic skin lesion that is similar to a clavus. It is an area of thickened epidermis with less defined borders and is also the result of repeated mechanical stress. Additionally, calluses lack the painful central core seen with clavi. Calluses most commonly present on the hands and feet. The older and the physically active are most commonly affected by clavi. Treatment focuses on symptomatic relief and lifestyle modification to prevent future clavus formation. By treating this painful and sometimes life-altering skin lesion, physicians can have a profound impact on their patients’ lives.
