Differentiating Staphylococcal Scalded Skin Syndrome (SSSS) and Stevens-Johnson Syndrome (SJS)/Toxic Epidermal Necrolysis (TEN)

Differentiating Staphylococcal Scalded Skin Syndrome (SSSS) and Stevens-Johnson Syndrome (SJS)/Toxic Epidermal Necrolysis (TEN)

Feature

SSSS

SJS/TEN

Typical patient population

Infants, young children, and adults with kidney failure or immunocompromise

Older adults

Usual trigger

Recent staphylococcal infection (toxin-mediated)

Medication exposure (eg, antibiotics, antiseizure medications, NSAIDs)

Mucous membrane involvement

Absent

Present and prominent

Systemic illness

Mild to moderate

Severe, multisystem involvement

Level of epidermal cleavage*

Intraepidermal, within the granular cell (outermost) layer of the epidermis

Subepidermal, at or below the basal cell

Pathophysiology

Exfoliative toxins cause keratinocyte detachment

Immune-mediated keratinocyte apoptosis

* Level of epidermal cleavage is determined by frozen section of a fresh skin specimen.

NSAIDs = nonsteroidal anti-inflammatory drugs.
