Erysipelas

Erysipelas is an acute, superficial form of bacterial cellulitis that primarily involves the upper dermis and superficial lymphatics. It is characterized by a sharply demarcated, erythematous, tender, and indurated plaque. Unlike deeper cellulitis, erysipelas has a distinct raised border and often presents with systemic toxicity, such as fever and chills.

The primary causative organism is Streptococcus pyogenes (Group A Beta-hemolytic Streptococcus). Occasionally, other streptococci (Groups B, C, or G) may be implicated. Infection typically occurs through a breach in the skin barrier, such as an abrasion, ulcer, insect bite, or interdigital tinea pedis.

The bacteria invade the epidermis and superficial dermis through minor skin trauma. Proliferation causes local inflammation and the production of streptococcal toxins, leading to vascular dilation and edema. The involvement of superficial lymphatics accounts for the sharply defined margins characteristic of the disease.

Erysipelas is most common in infants, the elderly, and individuals with impaired lymphatic drainage. It occurs globally with no significant gender predisposition, though prevalence is higher in populations with poor access to hygiene or high rates of skin trauma.

Lymphedema, venous insufficiency, diabetes mellitus, obesity, alcohol abuse, peripheral vascular disease, and chronic skin conditions like athlete's foot (tinea pedis).

A. Early Symptoms

• Sudden onset of localized redness


• Warmth and tenderness at the site


• Mild burning sensation B. Common Symptoms


• Sharply demarcated, raised, bright red plaque


• Fever and chills


• Regional lymphadenopathy


• Edema (peau d'orange appearance) C. Advanced Symptoms


• Bullae or vesicle formation


• Hemorrhagic crusting


• Intense pain and skin tension D. Emergency Symptoms


• High-grade fever, confusion, hypotension (sepsis)


• Rapid spread of erythema


• Necrosis of skin tissue

Inspection reveals a well-demarcated, glossy, erythematous plaque. Palpation demonstrates induration, increased local temperature, and extreme tenderness.

A. Clinical Assessment: Diagnosis is primarily clinical based on the well-demarcated border.
B. Laboratory Testing: Leukocytosis and elevated C-reactive protein.
C. Imaging Studies: Generally not required unless deep tissue involvement is suspected.
D. Functional Tests: Not applicable.
E. Biopsy Findings: Generally unnecessary; shows superficial dermal edema and neutrophil infiltration.
F. Genetic Testing: Not applicable.
G. Differential Diagnosis: Cellulitis, contact dermatitis, necrotizing fasciitis.

Complete Blood Count
Type: Blood Test
Purpose: Assess infection severity
Expected Findings: Elevated WBC count
Interpretation: Indicates systemic inflammatory response

Ultrasound: Used to rule out abscess or deep tissue collection (cellulitis vs. abscess).

Cellulitis: Indistinct borders.
Necrotizing Fasciitis: Rapid progression, pain out of proportion, systemic instability.
Contact Dermatitis: Pruritic rather than painful, history of exposure.

Bacteremia, endocarditis, septic arthritis, necrotizing fasciitis, and chronic lymphedema.

A. Lifestyle Modifications: Limb elevation and rest.
B. Preventive Measures: Treat tinea pedis, manage edema with compression.
C. Medical Treatment:

• Penicillins (Penicillin V, Amoxicillin)


• First-generation Cephalosporins (Cephalexin)


• Macrolides (for penicillin-allergic patients)

Good with prompt antibiotic therapy. Recurrence is common if underlying predisposing factors (e.g., tinea) remain untreated.

Good skin hygiene, daily moisturizing, and treatment of skin fissures.
