3. Definition
Erythroderma , which is also
known as Generalised
Exfoliative Dermatitis:
“An inflammatory dermatosis
which involves 90% or more of
the skin surface.”
(Gawkrodger, 2004)
4. Clinical Presentation
Four key points:
1. Patchy erythema becomes universal over 24-48
hours, accompanied by malaise, shivering and
pyrexia.
2. Scaling appears 2-6 day later, when the skin is hot,
dry, red and thickened.
3. Skin feels tight and itchy, and patients feel cold.
4. Scalp and body hair is eventually lost, whilst nails
become thickened or shed.
5. Pathology
Acute changes – Dermal/epidermal oedema and
inflammatory infiltrate.
Chronic changes – Lengthened rete ridges and
thickened epidermis.
Cytokines implicated: IL-1, IL-2, IL-8, ICAM-1, TNFα
and IFN-γ (Wilson et al, 1993)
Typical changes of underlying lesion.
10. Drug reaction
Drug reactions of the
toxic erythema or
mobillform type can
become
erythrodermic
Carbemazepine,
phenytoin, diltiazem,
cimetidine, gold,
allopurinol and
sulphonamides are
common causes.
(Gawkrodger, 2004)
13. Prognosis
Sigurdsson et al (1996) found a mortality rate of 43%
in 102 patients with erythroderma , although only 18%
of these deaths occurred as a direct result of the
patient’s erythroderma.
Drug induced disease carries a much better
prognosis than that caused by malignancy. Chronic
conditions like eczema and psoriasis could lead to a
relapsing remitting course.
14. Conclusion
A secondary process occurring as a result of ezcema,
psoriasis and lymphoma.
Of sudden onset, exfoliative, erythematous and
oedematous.
Serious complications can arise, which can be life
threatening.
Management involves close inpatient monitoring and
initially topical steroids.
