Callus - カルス胼胝
カルス (Callus) は、繰り返しの摩擦、圧力、その他の刺激に反応して形成される皮膚の肥厚領域です。たこは一般に無害で、水ぶくれを防ぐだけでなく、保護にも役立ちます。ただし、過剰に形成されると、皮膚潰瘍や感染症などの他の問題が発生することがあります。

治療 ― OTC医薬品

  • @左足(足底)と右足(外側)にタコがある。
  • Corns (calluses) 圧力がかかる場所、または靴が足を押す場所で、両足に対称的に発生します。圧力のない領域に同様の病変が発生した場合は、いぼを疑う必要があります。

Corns 繰り返しの摩擦や圧力によって発生します。 Corn は皮膚が厚くなった特定の領域ですが、 callus はより広範囲に広がっています。 Corns スポーツ選手や、靴の不均一な摩擦など足に問題がある人によく起こります。高齢者、糖尿病患者、切断患者にもよく見られます。 Corns は、独立した状態ではなく、症状として見るべきです。
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 は、ひっかかり症としても知られ、クリニックでよく見られる足の症状です。摩擦や圧力によって生じる皮膚の肥厚した部分で、痛みを伴うことがよくあります。たこやいぼと区別することが重要です。たこも似ていますが、中心核がなく、痛みはそれほどありません。治療の目的は、症状を軽減し、将来の魚の目予防です。この痛みを伴う症状を治療すると、特に高齢者や活動的な人にとって、患者の生活が大幅に改善されます。
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.
