Eosinophilic Cellulitis (Wells Syndrome): Symptoms, Causes, Treatment
متلازمة ويلز: التهاب النسيج الخلوي اليوزيني
Wells syndrome, or eosinophilic cellulitis, is a rare inflammatory skin disorder that can resemble bacterial infection. Assessment is needed before automatically prescribing antibiotics or steroids.
What is Eosinophilic Cellulitis (Wells Syndrome)?
Lesions may recur and leave temporary pigment changes. The name does not establish bacterial infection, although a genuine infection can mimic or coexist with it.

Symptoms
Red swollen areas may itch or burn and form plaques or blisters. Limbs and trunk can be affected, with episodes resolving and recurring.
Causes
Cases may be unexplained or associated with medicines, insect bites or another illness. A reported association does not prove an individual trigger.
Risk factors
Different age groups can be affected. Universal cancer screening is not indicated for every case; history, examination and persistent findings guide targeted investigation.
Diagnosis
Assessment reviews medicines and exposures and may include skin biopsy. Blood eosinophilia or particular microscopic patterns support evaluation but are not diagnostic alone.
Treatment
Dermatology-directed care may include topical or systemic steroids and other options for recurrent disease. Treat confirmed infection and review triggers rather than repeating antibiotics without evidence.
Complications
Recurrence, pigment change or occasional secondary infection may occur. Persistent marked eosinophilia or other-organ symptoms requires investigation for broader causes.
Prevention
There is no guaranteed prevention. Avoid a confirmed trigger in consultation with the clinician, protect the skin and do not stop essential medication on suspicion alone.
When to see a doctor
Rapidly spreading rash with fever, severe pain or extensive blistering needs urgent assessment. Breathlessness, facial swelling or marked deterioration requires emergency care.
