Erysipelas: Symptoms, Photos, AI Check 🚨 ICD-10: A46 | ICD-11: 1B70

Erysipelas is an acute bacterial inflammation of the skin and superficial lymphatic vessels. The condition usually develops rapidly and presents with bright redness of the skin, swelling, tenderness, and fever. The legs are most commonly affected, while the face and other parts of the body are involved less frequently.

The main cause of erysipelas is bacteria, most commonly streptococci. They enter the skin through small cracks, abrasions, fungal infections of the feet, or other damage to the skin barrier. The condition is not among the most common skin infections, but it occurs fairly often, especially in adults and older people.

Erysipelas requires timely treatment, as without therapy the inflammation may spread and lead to complications. In most cases, however, the condition responds well to antibiotic treatment.

What to Do If You Suspect Erysipelas

If a bright, painful area of redness suddenly appears on the skin and is accompanied by fever, weakness, or chills, it is important to seek medical attention as soon as possible. Diagnosis and treatment are usually handled by a dermatologist, primary care physician, or infectious disease specialist.

Before seeing a doctor, it is recommended to:

• limit stress on the affected area;
• avoid applying aggressive ointments or compresses on your own;
• avoid warming the inflamed area;
• monitor body temperature and overall well-being.

If there is severe pain, rapid spread of redness, high fever, or worsening condition, medical attention is especially urgent.

Symptoms should not be ignored or treated only with home remedies. Without proper therapy, the infection may spread deeper and cause complications.

What Erysipelas Looks Like

Erysipelas usually begins as a bright red area of skin with clearly defined borders. The inflamed area appears swollen, feels warm to the touch, and is painful.

The most common locations are:

• lower legs;
• feet;
• face;
• arms.

The redness may rapidly increase in size. In some cases, blisters filled with fluid or small hemorrhages appear on the skin surface.

The skin in the inflamed area often becomes firm and tense. Some people also experience significant weakness, chills, and high fever.

Main Symptoms

Erysipelas is characterized by a sudden onset. Symptoms usually develop quickly — within several hours or days.

Main symptoms include:

• bright redness of the skin;
• swelling;
• tenderness;
• a feeling of heat in the affected area;
• fever;
• weakness;
• chills;
• headache.

Nearby lymph nodes may sometimes become enlarged. In severe cases, blisters or areas of bleeding into the skin may develop.

Causes of the Condition

The main cause of erysipelas is a bacterial infection. The condition is most commonly caused by group A β-hemolytic streptococci.

The bacteria enter through breaks in the skin, even if they are very small and barely noticeable.

Factors that increase the risk of the condition include:

• cracked and dry skin;
• athlete’s foot;
• chronic swelling of the legs;
• varicose veins;
• diabetes mellitus;
• obesity;
• weakened immune system;
• chronic skin conditions.

Recurrent episodes of erysipelas are more common in people with impaired lymphatic drainage or chronic swelling.

How the Condition Develops

After bacteria enter the skin, an inflammatory reaction develops. The body attempts to fight the infection, causing blood vessels to dilate and leading to redness and swelling.

Streptococci may spread through the superficial lymphatic vessels of the skin. This is why the inflammation can sometimes rapidly increase in size.

With severe inflammation, the normal function of the skin and lymphatic system becomes impaired. If the condition recurs repeatedly, chronic swelling and tissue thickening may develop.

Forms and Types

Erythematous Form

The most common type. It presents with bright redness and swelling of the skin.

Bullous Form

Blisters filled with clear or cloudy fluid appear on the inflamed skin.

Hemorrhagic Form

Small hemorrhages develop in the skin. This form is usually more severe.

Recurrent Erysipelas

Repeated episodes of inflammation in the same area. Most commonly occurs on the legs.

When to See a Doctor

Medical attention is necessary with any suspicion of erysipelas, especially if:

• the redness is rapidly spreading;
• the temperature rises;
• severe pain develops;
• blisters appear;
• the overall condition worsens;
• inflammation develops in the presence of diabetes or varicose veins;
• the condition recurs.

Timely treatment helps reduce the risk of complications and speeds up recovery.

Treatment

The main treatment for erysipelas is antibacterial medication prescribed by a doctor. In most cases, therapy quickly stops the spread of the infection.

Additional recommendations may include:

• rest for the affected area;
• skin care;
• treatment of underlying conditions;
• reduction of swelling;
• management of chronic circulation and lymphatic drainage disorders.

In severe cases or when complications occur, hospital treatment may sometimes be required.

After recovery, it is important to pay attention to skin care and prevention of repeated skin damage. This is especially important for people with chronic swelling, fungal foot infections, or varicose vein disease.

Questions and Answers

Is erysipelas contagious?

Erysipelas is associated with a bacterial infection, but the condition is generally not considered highly contagious in everyday settings. The risk of transmission is significantly lower than with many other skin infections.

Is erysipelas dangerous?

Yes, without treatment the condition may lead to complications, including spread of the infection, abscesses, and chronic lymphatic drainage disorders. That is why it is important to see a doctor if erysipelas is suspected.

Can erysipelas be completely cured?

In most cases — yes. However, some people may experience recurrent episodes, especially if provoking factors remain.

How is erysipelas different from cellulitis?

Erysipelas usually has more clearly defined borders of inflammation and affects the superficial layers of the skin and lymphatic vessels.

Can erysipelas recur?

Yes. Recurrences are fairly common, especially in people with chronic swelling and impaired lymphatic drainage.

Can warming ointments be applied to the inflammation?

No. Warming the area may worsen the course of the infection.

Why does erysipelas occur more often on the legs?

The legs are more prone to swelling, minor injuries, fungal infections, and circulation problems, which makes it easier for the infection to enter.

Does erysipelas leave marks?

After recovery, the skin usually heals well, but in severe or recurrent cases swelling and skin changes may persist.
