2. •A wart is a small growth with a
rough texture that can appear
anywhere on the body. It can
look like a solid blister or a small
cauliflower.
3. •Warts are caused by viruses in
the human papillomavirus (HPV)
family group
• People with a weakened
immune system are more likely
to have warts
4. Genital warts
• Most warts are harmless, but some strains of HPV
can cause warts on, in, or around the genitals.
• These warts can be more serious. In women, they
can potentially lead to cervical, anal, and
vulvovaginal cancer.
• In men, anal cancer and cancer of the glans
penis can also occur as a result of infection with
some types of genital warts.
5. Common warts
Common warts have a firm,raised, rough
surface and may appear cauliflower-like.
•They can occur anywhere, but they are most
common on the knuckles, fingers, elbows,
knees, and any area with broken skin.
6. Plantar warts
•Painful lumps appear on the soles of the feet,
heels, and toes.
•They usually grow into the skin because the
person's weight pushes onto the sole of the
foot. They normally have a small central black
dot surrounded by hard, white tissue.
•Plantar warts are often difficult to clear.
7. Plane warts
• Also known as flat warts, they grow most often on sun-
exposed areas.
• They tend to grow in larger numbers, possibly between 20
and 100. However, of all wart types, they are most likely to
disappear without treatment.
8. Filiform warts, or verruca filiformis
•Filiform warts are long and thin in shape.
They can grow rapidly on the eyelids,
neck, and armpits.
9. •Periungual warts grow under and around the
toenails and fingernails. They can be painful
and affect nail growth.

10. CAUSES
• HPV viruses cause the excessive and rapid growth of keratin, which
is a hard protein on the top layer of the skin.
• Different HPV strains cause different warts. The wart-causing virus
can be passed on by close skin-to-skin contact, and through contact
with towels or shoes.
• The virus can spread to other parts of the body through:
• scratching or biting a wart
• sucking fingers
• biting fingernails, if there are warts around the nails
• shaving the face or legs
• Having wet or damaged skin, and coming into contact with rough
surfaces increase the risk of infection.
11. .
•Risk factors
• People at higher risk of developing common warts
include:
• Children and young adults, because their bodies may not
have built up immunity to the virus
• People with weakened immune systems, such as those
with HIV/AIDS or people who've had organ transplants
