Plantar warts affect females slightly more often than males. Hyperkeratotic tissue reveals typical punctate hemorrhages, which represent thrombosed capillaries of the papilloma. Pathologic findings include acanthotic epidermis with hyperkeratosis. This occurs through breaks in the stratum corneum of the epidermis. Such exposure frequently is associated with using public showers.
Diagnosis typically is made on clinical grounds.
Treatment options include topical keratinolytic medications, cryotherapy, and surgery. Since plantar warts are epidermal, cautious treatment should not result in scarring. Topical keratinolytic and cauterizing agents Salicylic acid, cantharidin, and dichloroacetic acid are useful. Soak the affected area in warm water and dry it. Pare the top layer, and apply the chosen keratinolytic agent under tape occlusion.
