Study Notes
Staphylococcal Scalded Skin Syndrome (SSSS)
- SSSS is characterized by the separation of the epidermis from the dermis, occurring within the stratum granulosum.
- The separation space may contain acantholytic cells, which are cells that have detached from the epidermis.
- The rest of the epidermis appears normal, and there is minimal inflammation in the dermis.
- Localized bullous impetigo can have more inflammatory cells, including neutrophils.
- SSSS can be difficult to differentiate from toxic epidermal necrolysis (TEN).
- Lyell's initial description of TEN included cases that might have been SSSS.
- The age of onset of SSSS and TEN often overlap, but SSSS is more common in neonates and children.
- Frozen sections can help differentiate SSSS from TEN, as SSSS shows superficial subgranular epidermolysis, while TEN shows full-thickness epidermal necrosis and dermal-epidermal separation.
Staphylococcal Scalded Skin Syndrome (SSSS)
- All forms of SSSS are characterized by intraepidermal cleavage with splitting beneath and within the stratum granulosum
- The cleavage space may contain either partially or totally unattached acantholytic cells
- The remainder of the epidermis is unremarkable and the dermis contains few inflammatory cells.
- More inflammatory cells including neutrophils can be visualized in localized bullous impetigo
- The principal diagnostic problem is distinguishing generalized SSSS from toxic epidermal necrolysis (TEN)
- SSSS typically affects neonates and children, while TEN affects older individuals
- Frozen sections can rapidly differentiate the superficial subgranular epidermolysis in SSSS versus the characteristic full-thickness epidermal necrosis and dermal–epidermal separation seen in TEN
