The internal structure of metatarsal warts includes a soft core of keratin and a small black spot formed by the rupture and bleeding of the capillaries distributed around it. Metatarsal warts are found on the heel, between the toes, and on the front of the foot, mainly due to human papillomavirus infection. At the beginning of the disease, they appear as tiny, shiny papules that gradually grow to the size of a soybean or larger, and form a brownish-yellow or yellowish plaque with clear borders due to extrusion, surrounded by thickened keratinous rings. The internal structure of a plantar wart consists mainly of a loose keratinous soft core and small black dots (formed due to bleeding from ruptured capillaries). Under dermoscopy, a dark brown or brownish linear or punctate hemorrhagic sign in the center of the lesion can be observed, and it is painful to act upon. Although a few plantar warts are likely to disappear, most of them are likely to get worse.
