Introduction

Background

Erysipelas is a skin infection typically caused by group A beta-hemolytic streptococci, although other streptococcal groups are occasionally causative agents. Infection involves the dermis and lymphatics and is a more superficial subcutaneous infection of the skin than cellulitis. Erysipelas is characterized by intense erythema, induration, and a sharply demarcated border, which differentiates it from other skin infections.

For a CME activity, see Invasive Group A Streptococcal Disease in Nursing Homes, Minnesota, 1995-2006.

Pathophysiology

The skin is the primary organ system affected.

Frequency

United States

Increasing incidence has been noted since the late 1980s.

Mortality/Morbidity

Erysipelas generally is benign; however, it can be fatal when associated with bacteremia in very young, elderly, or immunocompromised patients. The mortality rate is less than 1% in treated cases.

Sex

Slight female predominance is observed.

Age

Infection occurs at extremes of age, but erysipelas is primarily a disease of adults.

Clinical

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
    • 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 affected in 5-20% of patients
  • Erythema is irregular with extensions that may follow lymphatic channels (lymphangitis).
    • Desquamation
    • Vesicles
    • Lymphadenopathy

Causes

  • Group A streptococci are the most common cause. 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
    • 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
