Cysts are noncancerous, closed pockets of tissue that can be filled with fluid, pus, or other material.
Cysts are common on the skin and can appear anywhere. They feel like large peas under the surface of the skin. Cysts can develop as a result of infection, clogging of sebaceous glands (oil glands), or around foreign bodies, such as earrings.
What Are the Symptoms of Skin Cysts?
Skin cysts usually are:
Smooth to the touch when they are rolled under the skin
How Are Skin Cysts Treated?
Cysts usually do not cause pain unless they rupture or become infected or inflamed. Most cysts do not disappear on their own without treatment. Some cysts may need to be drained to relieve symptoms. That involves piercing the cyst with a sharp object and draining it. That doesn't cure the cyst, however. Some inflamed cysts can be treated with an injection of cortisone medication to cause it to shrink. Cysts that do not respond to other treatments or reoccur can be removed surgically if they cause troublesome symptoms.
Cherry Angioma and Your Skin
A cherry angioma is a smooth, cherry-red bump on the skin.
Although cherry angiomas usually appear on the trunk of the body, they can occur nearly anywhere. The cause of cherry angiomas is not known and the growths usually appear on people over the age of 40.
What Are the Symptoms of Cherry Angiomas?
Cherry angiomas are small, bright red growths that are smooth. The size of the growths can vary from the size of a pinhead to about a quarter inch in diameter.
How Is a Cherry Angioma Treated?
In most cases, cherry angiomas do not require treatment. If they are cosmetically unappealing or are subject to bleeding, angiomas may be removed by lasers or electrocautery -- the process of burning or destroying tissue by use of a small probe with an electric current running through it. Removal may cause scarring.
