Calluses and corns arise from persistent continuous or intermittent pressure where there is an insufficient amount of soft tissue between skin and the underlying bone. Pain from corns results from their hard conical corn pointing to the bone. Foot deformation is the most common cause. Warts may develop as myrmecia, mosaic and vulgar warts. Surgical treatment is usually not indicated since the rate of recurrences is as high as with conservative therapy, and the resulting scars may lead to the same complaints.
