wartor verrucaWell-defined growth on the skin, usually caused by a papillomavirus, which triggers overproduction of epidermal cells. This may lead to a single long-standing wart, profuse local spread (especially in moist areas), or warts in various parts of the body. The most common type is a round bump with a dry, rough surface. Warts are usually painless except in pressure areas, such as the sole of the foot (plantar wart). Genital warts are merely a nuisance unless they become large or numerous enough to interfere with urination, defecation, or childbirth, but some viral strains are associated with cervical cancer. Warts are considered contagious. They may be removed by applying acids, cryotherapy, electrocautery, or surgery; they sometimes disappear spontaneously. verruca 1. Pathol a wart, esp one growing on the hand or foot 2. Biology a wartlike outgrowth, as in certain plants or on the skin of some animals verruca [və′rü·kə] (biology) A wartlike elevation on the surface of a plant or animal.

Occasionally, these benign tumors need to be separated from verruca vulgaris (wart), solar lentigo, squamous cell carcinoma, and melanoma, but separation is usually straightforward, relying on deeper levels cut into the block rather than on special studies. Each verruca was cleaned with alcohol, and the wart horn was pared with a scalpel to decrease the skin impedance. The most common manifestations of oral HPV infection are the various types of benign warts, which include the squamous papilloma (SP), verruca vulgaris (VV), condyloma acuminatum (CA) and a distinct entity known as focal epithelial hyperplasia (FEH). |
