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. A skin cyst is one that forms just under the skin.
Skin cysts are thought to form around trapped keratin cells, the cells that make up the relatively tough outer layer of skin.
These cysts are not contagious.
Anyone can get a skin cyst, but they are more common in people over the age of 18, with acne, or with skin lesions.
Symptoms include the appearance of a small, rounded lump under the skin. cysts are normally painless unless they are infected, when they will be red and sore and contain pus.
diagnosis is made through physical examination. a small cyst can be left alone, although if it is unsightly or large enough to interfere with movement, it can be removed with a simple procedure performed in a doctor’s office. An infected cyst must be treated so that the infection does not spread.
Main symptoms: skin-colored armpit lump, marble-sized armpit lump, small armpit lump
Symptoms that always occur with a skin cyst: skin-colored lump in the armpit
urgency: wait and watch
severe skin abscess
A skin abscess is a deeper skin infection that is usually caused by bacteria seen on the skin. recently, infections are most often caused by staphylococci. aureus (puts “staph” in “staph infections”). if the infection begins to spread, urgent treatment is required.
You should drive to the nearest emergency room as it looks like your infection may be spreading. antibiotics will likely be prescribed. Surgery may be required to remove the entire abscess after the swelling has subsided. do not drain the abscess yourself.
main symptoms: fatigue, fever, painful lump in the neck, marble-sized lump in the neck, pink or red lump in the neck
Symptoms that always occur with a severe skin abscess: pink or red lump on the neck, red lump
urgency: hospital emergencies
Lipoma is a word that translates to “fatty tumor,” but a lipoma is not cancer. it is simply a growth of fat between the muscle layer and the skin above.
The exact cause is unknown. the condition is hereditary and is associated with other unusual syndromes such as painful adiposis, which is similar. Lipomas appear more frequently after the age of 40.
Symptoms include a soft lump under the skin that is easily moved, about two inches across. A lipoma is painless unless its growth irritates the nerves around it. they are most often found on the back, neck, and abdomen, and sometimes on the arms and upper legs.
It’s a good idea to have any new or unusual growth checked by a medical provider, just to make sure it’s benign.
diagnosis is made through a physical exam, biopsy, and imaging, such as an ultrasound or CT scan.
Most of the time, treatment is not necessary unless the lipoma is unsightly or interferes with other structures. it can be removed by surgery or liposuction.
Main symptoms: skin-colored groin lump, marble-sized groin lump, small groin lump
symptoms that always occur with lipoma: skin-colored lump in the groin
urgency: wait and watch
enlarged lymph nodes in the groin
Enlarged lymph nodes occur when the node becomes larger as it fills with inflammatory cells. this is often the result of an infection, but can occur without a known cause.
You should talk to a health care provider about whether or not you need to check your lymph nodes. enlarged lymph nodes will usually shrink on their own. To speed up the process, try applying a warm, wet compress to the affected area.
main symptoms: lump in the groin, mobile lump in the groin
Symptoms that always occur with enlarged lymph nodes in the groin: Lump in the groin
Symptoms that never occur with enlarged lymph nodes in the groin: fever, unintentional weight loss, hard lump in the groin
urgency: phone call or face-to-face visit
A dermatofibroma is a fairly common skin growth that usually appears on the lower legs, but can appear anywhere on the body. These mole-like growths are benign (not cancerous).
The cause is unknown, although a dermatofibroma may develop after a minor injury. the growths are not contagious.
Dermatofibromas are more common in adults and are rarely found in children.
Symptoms include a hard, raised growth that is red, pink, or brown and less than a half-inch wide. They’re usually painless, but they can be tender or itchy, and they can appear singly or in groups.
A medical provider should view any new skin growth, especially if the growth is very dark in color or changes shape or appearance quickly.
diagnosis is made by physical examination and sometimes biopsy.
A dermatofibroma does not require treatment unless it interferes with clothing or is unsightly. they can be surgically removed, although this will leave a scar and the growth may eventually return.
