Answer

Flat warts also are termed plane warts or verruca plana. They are characterized as flat or slightly elevated flesh-colored papules that may be smooth or slightly hyperkeratotic. They range from 1-5 mm or more, and numbers range from a few to hundreds of lesions that may become grouped or confluent. These warts may occur anywhere; however, the face, hands, and shins tend to be the most common areas. They may appear in a linear distribution as a result of scratching or trauma (Koebner phenomenon). Regression of these lesions may occur, which usually is heralded by inflammation.
