Study Notes
Cellulitis
- Acute skin and soft tissue infection (SSTI) beginning in the epidermis and dermis, spreading to subcutaneous layers.
- Bacteria enter through breaks in the skin, leading to infection.
- Approximately 30% of blood samples from cellulitis patients show bacteremia.
- Symptoms include non-elevated lesions with swelling (edema), redness (erythema), poorly defined margins, and the affected area feels hot, tender, and painful.
Lymphangitis
- Inflammation of lymphatic vessels often resulting from infection.
- Common causes include puncture wounds, infected blisters, or skin lesions, frequently originating from cellulitis.
- Symptoms include red, subcutaneous lines extending from the infection site, indicating serious and rapid progression.
Erysipelas
- An acute, distinct form of cellulitis affecting superficial skin layers and cutaneous lymphatics, causing blockage of dermal lymphatics.
- Known colloquially as “St. Anthony’s fire.”
- Symptoms include skin rash, elevated lesions, redness, swelling, pain, tenderness, and fever.
- Common among infants, young children, the elderly, and individuals with nephrotic syndrome (kidney damage).
Impetigo
- Superficial epidermal skin infection predominantly seen in children.
- Highly communicable, spreading through close contact, especially in daycare settings and among siblings.
- Common in neonates.

Overview of Erysipelas
- Erysipelas is an acute form of cellulitis, primarily affecting the skin's superficial layers.
- It involves the cutaneous lymphatics and is characterized by the blockage of dermal lymphatics.
- Commonly referred to as "St. Anthony’s fire."
Symptoms
- Presents with a skin rash that is often elevated.
- Marked by erythema (redness) surrounding the affected area.
- Associated with edema (swelling) of the skin, pain, and tenderness.
- Can include systemic symptoms such as fever.
At-Risk Populations
- More common in infants and young children due to developing immune systems.
- Elderly individuals are also at higher risk because of age-related skin and health factors.
- Patients with nephrotic syndrome (kidney damage) are particularly susceptible to the condition.
