Benign Skin Growths

Skin growths are common and can be anything from a mole to a skin tag. Here’s why they happen and how to treat them.

Sarcoidosis causes inflammation, usually in lungs, skin, or lymph nodes. It can affect many organs in your body or just one or two, and in many different ways.

A canker sore (also called an aphthous ulcer) is a small, painful ulcer inside your mouth. It is round and shallow with a whitish-grey base surrounded by a red ring. It is not contagious and usually goes away within 1 to 2 weeks but can be very uncomfortable.

Is Your Itchy Foot Athlete’s foot?

Athlete’s foot (known medically as tinea pedis) is a fungal infection that causes scaly, itchy feet. It usually starts between the toes because that area is extra moist. Athlete’s foot is very contagious.

Eczema (Atopic Dermatitis): Causes and Treatments

Eczema is a chronic skin disease that causes itchy, inflamed skin. It’s also called atopic dermatitis. The rash comes and goes. The itching can be eased with various treatments, and you can take steps to reduce flare-ups.

Basal Cell Carcinoma: A Treatable Skin Cancer

Basal cell carcinoma is the most common kind of skin cancer. It’s caused by repeated exposure to the sun. It’s rarely fatal, but it’s important to treat right away so it doesn’t get worse—that can lead to more complicated surgery and scars.

Dermatofibromas are harmless, noncancerous skin bumps. They are usually small, firm, pink to light brown and often develop on legs. They are caused by an overgrowth of skin cells called fibroblasts. They do not go away on their own, but can be removed by a doctor if troublesome.

Skin Abscess: Symptoms and Treatment

A skin abscess is a painful lump beneath the skin that fills with pus and bacteria. Larger abscesses usually need to be treated by a doctor, who will drain them and possibly prescribe antibiotics.

Paronychia: Nail Infection

Paronychia is when the skin around your nails gets infected. It is caused by bacteria or yeast. The skin around the nail might get red, swollen, painful, and become filled with pus. Most cases get better in less than a week if treated.

Cellulitis: A Rash That Needs Treatment

Cellulitis is a bacterial infection of the skin and the soft tissue beneath the skin. Cellulitis usually occurs when bacteria enter the skin through small cuts or scrapes. It causes a painful, red, swollen rash and needs to be treated with antibiotics.
