Acute infection of the upper dermis and superficial lymphatics

Erysipelas is an acute bacterial infection of the upper dermis and superficial lymphatics, typically caused by Streptococcus pyogenes, also known as group A streptococcus. It is characterized by a well-defined, raised, red area of skin that is often warm to the touch and painful.

Signs and symptoms

Erysipelas presents with a sudden onset of symptoms, including:

Affected skin that appears red, swollen, and warm
A well-demarcated, raised edge of the affected area
Pain and tenderness in the affected area
Fever and chills
Swollen and tender lymph nodes

The infection most commonly affects the face and legs, but it can occur on any part of the body.

Causes

Erysipelas is primarily caused by Streptococcus pyogenes, a bacterium that is part of the group A streptococci. The bacteria enter the skin through minor cuts, abrasions, or other breaks in the skin barrier. Risk factors for developing erysipelas include:

Diagnosis

Diagnosis of erysipelas is primarily clinical, based on the characteristic appearance of the skin and the rapid onset of symptoms. Laboratory tests are not usually necessary, but a complete blood count may show elevated white blood cells, indicating infection. In some cases, a blood culture may be performed to identify the causative organism.

Treatment

The mainstay of treatment for erysipelas is antibiotic therapy. Penicillin is the antibiotic of choice, given its effectiveness against Streptococcus pyogenes. For patients allergic to penicillin, alternatives such as erythromycin or clindamycin may be used. In addition to antibiotics, supportive care includes:

Rest and elevation of the affected limb
Analgesics for pain relief
Hydration

Complications

If left untreated, erysipelas can lead to complications such as:

Prevention

Preventive measures for erysipelas include:

Maintaining good skin hygiene
Prompt treatment of skin injuries
Managing underlying conditions such as diabetes and venous insufficiency

-==Causes and Pathogenesis==
-Erysipelas is typically caused by Group A streptococci, specifically Streptococcus pyogenes. It usually enters the body through breaks in the skin, such as cuts, abrasions, or insect bites. Once the bacteria enter, they release toxins that result in inflammation and the characteristic rash of erysipelas.<ref name="Lancerotto">{{Cite journal|last=Lancerotto|first=L.|date=2012|title=Erysipelas and cellulitis|journal=Curr Infect Dis Rep|volume=14|issue=6|pages=598-607|doi=10.1007/s11908-012-0290-7}}</ref>

+Erysipelas presents with a sudden onset of symptoms, including:
-The hallmark feature of erysipelas is a fiery red, swollen, and warm skin rash with a sharply demarcated border. The affected area often has a raised, 'orange-peel' appearance. Accompanying systemic symptoms can include fever, chills, fatigue, and a general feeling of being unwell.
