2.2.6 Staphylococcal scalded skin syndrome (SSSS)
Grading & Level of Importance: C
Staphylogenic Lyell`s syndrome.
SSSS: no exact data.
SSSS: acute exfoliative dermatitis primarily in small children following staphylogenic infections with lysophage group II exfoliative toxins.
Aetiology & Pathogenesis
Toxin-mediated epidermolytic dermatosis, characterized by erythema and widespread loss of the superficial epidermal layers, resembling burn. Causative agent is toxin-producing (exfoliative toxins A and B) Staphylococcus aureus toxins acting via serin proteases desmoglein 1 in the upper epidermal layers.
Signs & Symptoms
Following a staphylococcal infection, initially erythema resembling scarlet fever followed by small unstable blisters which quickly erode and lead to widespread skin loss similar to grade II burns. Acute course, systemically ill patient. Nikolski sign positive.
Laboratory & other workups
Intensive care laboratory data regarding kidney, liver and blood, albumin.
Acantholytic cleft in the S.granulosum and blister roof only contains stratum corneum (in contrast to TEN with full-thickness epidermal damage), subcorneal blisters and bullae.
Rapid onset within hours to two days.
History, clinical feature, histology (frozen section of blister roof).
Prevention & Therapy
Children are to be admitted immediately to intensive care unit. Antibiotics covering resistant staphylococci according to resistogram; immunoglobulins are recommended. Fluid replacement as in burn patients, elimination of staphylococcal foci; antimicrobial disinfectant therapy (baths, compresses). Paracetamol, no NSAIDs.
Immediate biopsy for cryosection to visualize the location of blister for differential diagnosis.
