History
Erysipelas is a febrile illness with dermatological findings, characterized by an abrupt onset of illness with initial fever and chills followed by a painful rash occurring 1-2 days later.
Muscle and joint pain may accompany illness.
Nausea may be present.
Headache and other systemic manifestations of an infectious process may occur.
Skin discomfort is noted.
Physical
The patient may appear healthy or toxic depending on the extent of infection.
Fever is common.
Dermatologic signs include the following:
- Painful, erythematous, and edematous rash
- Sharply-raised border with abrupt demarcation from healthy adjacent skin
- Condition found in lower extremities in 70-80% of patients; face, as in the image below, affected in 5-20% of patients[3]
Facial erysipelas exhibiting classic fiery-red plaque with raised, well-demarcated borders.
Erythema is irregular with extensions that may follow lymphatic channels (lymphangitis).
- Desquamation
- Vesicles
- Lymphadenopathy
Causes
Group A streptococci are the most common cause.[4] Less common etiologies include group G, C, and B streptococci and, rarely, staphylococci.
A defect in skin barrier allows the infection to occur. Infection may occur after trauma, abrasions, skin ulcers, insect bites, eczema, and psoriatic lesions.
Other predisposing factors include the following:
- Lymphatic obstruction or edema
- Saphenous vein grafting in lower extremities
- Status postradical mastectomy
- Immunocompromised patients, including patients who are diabetic or alcoholic
- Arteriovenous insufficiency
- Paretic limbs
