Staphylococcal scalded skin syndrome

Staphylococcal scalded skin syndrome is a skin condition caused by a bacterial infection that mainly affects young children and infants. It involves the skin becoming red, tender, and peeling, resembling a severe burn or scald. This happens because toxins produced by the bacteria damage the top layers of the skin, causing them to separate and shed. The condition primarily affects the skin and mucous membranes, leading to pain and increased risk of infection. It can cause fever and general discomfort, and the skin changes can make it hard to maintain normal body temperature and fluid balance. Early recognition is important because the skin barrier is compromised, increasing the risk of serious complications. The condition usually improves with appropriate medical care.

Staphylococcal scalded skin syndrome (SSSS) is a dermatologic disorder caused by exfoliative toxins (exfoliatins) produced by certain strains of Staphylococcus aureus. These toxins target desmoglein-1, a cadherin protein critical for keratinocyte adhesion in the superficial epidermis, leading to intraepidermal cleavage and widespread epidermal detachment. SSSS primarily affects neonates and young children due to their immature renal clearance of toxins and underdeveloped immune response. Clinically, it presents with fever, diffuse erythema, and large areas of skin sloughing resembling a scald injury, often sparing mucous membranes. The condition is significant because it disrupts the skin barrier, increasing the risk of secondary infections and fluid loss. Diagnosis is based on clinical presentation and confirmed by identifying S. aureus infection and characteristic histopathology showing superficial epidermal splitting.
