Staphylococcal scalded skin syndrome

Overview & Definition

A fretful, febrile infant whose skin turns scarlet and then peels off in sheets is one of the most arresting sights in paediatrics, and staphylococcal scalded skin syndrome is the diagnosis that explains it. Phage-group-II Staphylococcus aureus, often colonising a trivial focus such as a sticky eye or an umbilical stump, releases exfoliative toxins A and B that travel in the blood and split the superficial epidermis. The result is tender erythema, fragile blisters, and widespread desquamation that looks like a scald but heals without scarring in a child who is treated promptly. [2]

The illness belongs to the family of staphylococcal exfoliative toxin diseases, which span from localised bullous impetigo at one end to generalised SSSS, also known as Ritter disease, at the other. The dividing line is whether the toxin stays local or reaches the circulation, and that in turn depends on the bacterial strain and on the host's ability to clear the toxin through the kidneys. Infants and children under six years cannot excrete the toxin as efficiently as adults, which is why this is overwhelmingly a disease of the very young. [1]

The single most important clinical point is that the mucous membranes are spared. The toxin cleaves desmoglein 1, which is expressed in the superficial epidermis of skin but is compensated for in mucosa by desmoglein 3, so the mouth, eyes, and genital surfaces remain intact. This single fact separates SSSS from Stevens-Johnson syndrome and toxic epidermal necrolysis, in which mucosal involvement is the rule and the split is full-thickness. Getting that distinction right at the bedside dictates the antibiotic choice, the prognosis, and the conversation with a frightened family. [3]
