Painless way to illustrate corn

A corn, also known as a "clavus," "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, clinicians need to distinguish a corn 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 in patients exposed to unequal friction force from footwear or gait problems, including older adults, patients with diabetes, and amputees. It should be regarded as a symptom rather than an effective disease.[1][2][3]
