Definition and Overview of Erysipelas
Erysipelas is a superficial bacterial infection of the skin that typically affects the face, legs, or arms. It is caused by bacteria, most commonly Streptococcus pyogenes (group A streptococcus), which enter the skin through a break in the skin, such as a cut, abrasion, or insect bite.
Clinical Presentation
Erysipelas typically presents with a red, swollen, and tender area of skin that is warm to the touch. The affected area may also be painful and have a burning or itching sensation. In severe cases, the infection can spread to the underlying tissues, causing cellulitis or abscesses.
Causes and Risk Factors: Erisipela
Erysipelas is primarily caused by a bacterial infection, most commonly by Streptococcus pyogenes, also known as Group A streptococcus (GAS).
Certain factors increase the risk of developing erysipelas, including:
Predisposing Conditions
- Lymphedema: A condition that causes fluid buildup in tissues, often in the legs or arms.
- Leg ulcers: Open sores on the legs that can become infected.
- Diabetes: A chronic condition that impairs the body’s ability to heal wounds.
- Obesity: Excess weight can put pressure on lymphatic vessels, increasing the risk of fluid buildup and infection.
Other Risk Factors
- Skin breaks or wounds: Any break in the skin can provide an entry point for bacteria.
- Poor hygiene: Inadequate hygiene practices can increase the risk of skin infections.
- Weakened immune system: Individuals with weakened immune systems are more susceptible to infections.
- Insect bites or animal scratches: Bites or scratches can introduce bacteria into the skin.
Pathophysiology and Progression
Erysipelas is a bacterial infection that affects the superficial layers of the skin and the underlying lymphatic channels. The pathophysiology of erysipelas involves the invasion of bacteria, typically Streptococcus pyogenes or Staphylococcus aureus, into the skin through breaks in the skin’s barrier, such as cuts or abrasions. Once the bacteria enter the skin, they multiply and spread rapidly through the lymphatic channels, causing inflammation and swelling.
Initial Stage
The initial stage of erysipelas is characterized by the development of a localized area of redness, warmth, and swelling on the skin. The affected area is often well-demarcated and has a raised, sharply defined border. The skin may also become tense and shiny, and the patient may experience pain and tenderness.
Progressive Stage
As the infection progresses, the bacteria continue to spread through the lymphatic channels and deeper layers of the skin. This can lead to the formation of bullae (fluid-filled blisters) and vesicles (small, raised, fluid-filled sacs). The affected area may also become more extensive and the skin may become discolored.
Advanced Stage
In severe cases, erysipelas can lead to systemic complications, such as sepsis. Sepsis is a life-threatening condition that occurs when bacteria enter the bloodstream and spread throughout the body. Risk factors for severe erysipelas include diabetes, obesity, and a weakened immune system.
Differential Diagnosis
Differentiating erysipelas from other skin infections is crucial for appropriate treatment and management. Key features that distinguish erysipelas include its characteristic raised, well-demarcated, and erythematous borders, along with the presence of lymphedema and systemic symptoms like fever and chills.
Comparative Clinical Features
The table below compares the clinical features of erysipelas with those of other common skin infections:
| Characteristic | Erysipelas | Cellulitis | Impetigo | Stasis Dermatitis |
|---|---|---|---|---|
| Borders | Raised, well-demarcated | Indistinct | Sharply demarcated | Irregular |

Diagnostic Tests and Procedures
Confirming erysipelas requires a combination of clinical examination and diagnostic tests. These tests aim to identify the presence of bacterial infection, rule out other conditions, and guide treatment decisions.
The choice of diagnostic tests depends on the severity of the infection, the patient’s overall health, and the availability of resources.
Skin Biopsy
A skin biopsy involves removing a small sample of the affected skin for examination under a microscope. This test can confirm the presence of bacteria and rule out other skin conditions with similar symptoms.
Culture
A culture involves collecting a sample of fluid or tissue from the affected area and growing it in a laboratory to identify the specific bacteria causing the infection.
Imaging
Imaging tests, such as ultrasound or MRI, may be used to assess the extent of the infection and rule out underlying complications like abscess formation.
Differential Diagnosis
Erysipelas shares similar symptoms with other skin infections and conditions. Differential diagnosis is crucial to rule out these conditions and ensure appropriate treatment.
Common Differential Diagnoses

- Necrotizing fasciitis
- Lymphangitis
- Deep vein thrombosis (DVT)
- Stasis dermatitis
Treatment Options
The primary treatment for erysipelas is antibiotics. The choice of antibiotic and the duration of therapy depend on the severity of the infection.
For mild cases of erysipelas, oral antibiotics such as penicillin or erythromycin are usually effective. For more severe cases, intravenous antibiotics such as vancomycin or clindamycin may be necessary.
Duration and Dosage of Antibiotic Therapy
The duration of antibiotic therapy for erysipelas typically ranges from 7 to 10 days. The dosage of the antibiotic will depend on the type of antibiotic being used and the severity of the infection.
Surgical Debridement
Surgical debridement may be necessary in some cases of erysipelas, such as when there is a large area of skin involvement or when the infection is not responding to antibiotic therapy.
Indications for Hospitalization
Hospitalization may be necessary for patients with severe erysipelas, such as those who have a high fever, chills, or other systemic symptoms.
Adjunctive Therapies
Adjunctive therapies, such as elevation and compression, can help to reduce swelling and pain in erysipelas.
Prevention and Recurrence
Erysipelas can be a recurrent infection, but there are steps you can take to prevent it from coming back.
Hygiene and Wound Care
