Overview
Eosinophilic cellulitis, also known as Wells syndrome, is a rare inflammatory condition characterized by recurrent episodes of painful subcutaneous edema and infiltration with eosinophils, often without a definitive cause 1.Diagnosis
Clinical Presentation: Subcutaneous nodules, skin swelling, and erythema 1.
Histopathology: Characteristic eosinophilic infiltration in biopsy specimens 1.
Laboratory Tests: Elevated peripheral eosinophil counts 1.
Imaging: Not typically required but may show subcutaneous edema 1.Management
First-Line Treatments:
- Corticosteroids: High-dose systemic corticosteroids are often used to control acute episodes 1.
Adjunctive Treatments:
- Immunosuppressive Agents: In refractory cases, consider azathioprine or other immunosuppressants 1.
- Anti-Eosinophil Agents: Such as mepolizumab, though specific dosing is not detailed in the abstract 1.Special Populations
Pediatrics: Subcutaneous nodules may present early in childhood, suggesting congenital onset is possible 1.
Pregnancy: Speculative link to maternal medication exposure; further research needed 1.Key Recommendations
Initiate high-dose systemic corticosteroids for acute exacerbations of eosinophilic cellulitis (Evidence: Moderate 1).
Consider immunosuppressive therapy in patients with recurrent or refractory disease (Evidence: Weak 1).
Monitor for early signs of disease in pediatric patients, recognizing subcutaneous nodules as potential initial presentations (Evidence: Expert opinion 1).References
