Verruca plana

Verruca plana, also know as a "flat wart," is a reddish brown or flesh-colored, slightly raised, flat-surfaced, well-demarcated papule of 2 to 5 mm in diameter. Upon close inspection, these lesions have a surface that is "finely verrucous." Most often, these lesions affect the hands and/or face, and a linear arrangement is not uncommon.
