Wart Warts, also called common warts or verrucae, are small, rough, rounded growths on the top layer of the skin. Common warts are caused by the human papilloma virus (HPV) and are contagious through direct contact. Treatment is often beneficial.
Skin cyst
A cyst is a small sac or lump, filled with fluid, air, fat, or other material, that begins to grow somewhere in the body for no apparent reason. Symptoms include the appearance of a small, rounded lump under the skin.
- Cysts are normally painless unless infected, when they will be reddened and sore and contain pus.
Boil (furuncle)
Irritation caused by clothes or anything else rubbing the skin can cause the skin to break down and allow bacteria to enter.
- Treatment may involve incision and drainage of the infection, followed by creams to apply to the site of the boil and/or a course of antibiotic medicine.

Lipoma
This is a growth of fat between the muscle layer and the skin above it. It is painless unless its growth is irritating the nerves around it. Symptoms include a soft, easily moveable lump beneath the skin, about two inches across.
- Diagnosis is made through physical examination, biopsy, and imaging. Most of the time, treatment is not necessary unless the lipoma is unsightly or is interfering with other structures.
Skin abscess
A large pocket of pus that has formed just beneath the skin. It is caused by bacteria getting under the skin, usually through a small cut or scratch, and beginning to multiply.
- The body fights the invasion with white blood cells, which kill some of the infected tissue but form pus.
Dermatofibroma
A common skin growth that usually appears on the lower legs, but may appear anywhere on the body. Symptoms include a hard, raised growth that is red, pink, or brown and less than half an inch across.
- Most common in adults and rarely found in children. Diagnosis is made through physical examination and sometimes biopsy.
Basal cell carcinoma
Most commonly seen in people with a history of sunburns, previous skin cancer, and a weakened immune system.
- Treating depends on location, size, and medical history. Treatment options include cutting out the bump, freezing it, or using medicated skin cream.
Pimple
Also called comedones, spots, blemishes, or “zits,” they are small skin eruptions filled with oil, dead skin cells, and bacteria.
- Pimples often first start appearing at puberty, when hormones increase the production of oil in the skin and sometimes clog the pores. Symptoms include blocked pores that may appear flat and black on the surface, because the oil darkens when exposed to the air.
- Blurred, white, pus-filled blisters surrounded by reddened skin.
Molluscum contagiosum
Also called “water warts,” this is a common, benign, viral skin infection that causes a rash of bumps that may appear anywhere on the body. Spread through direct contact with the bumps, including sexual contact.
- Most susceptible are children under age 10. Symptoms include rash of small, pale bumps with a pit in the center.
