Abstract
- A corn is a circumscribed hyperkeratotic lesion with a central conical core of keratin that causes pain and inflammation. Corns result from hyperkeratosis, which is caused by an increase in keratinocyte activity associated with stimulation of the epidermis from chronic pressure or friction on the skin. The conical core in a corn, which is a thickening of the stratum corneum, is a protective response to the mechanical trauma. We experienced a man who developed a corn on the buttock, which is an unusual site.
