L98.3
Eosinophilic cellulitis [Wells]
Clinical Classification Guidelines
Medical Intelligence & Overview
Eosinophilic cellulitis, commonly known as Wells syndrome, is a rare inflammatory skin condition characterized by sudden onset of skin swelling, redness, and tenderness. It typically presents as areas of inflamed skin that resemble bacterial cellulitis but are caused by an allergic or immune response rather than infection. The condition often affects adults and can be recurrent, resulting in temporary skin lesions that may resolve on their own or require medical intervention.
Causes & Symptoms
Clinical Causes: Allergic reactions to medications or environmental allergens Underlying immune system disorders Infections that trigger immune responses Idiopathic cases where no specific cause is identified Exposure to certain drugs or chemicals
Key Symptoms: Swollen, red, and tender skin areas Enlarged, firm plaques or patches Itching or burning sensations Presence of blistering or pustules in some cases Recurrent episodes of skin inflammation that resolve and recur at different sites Fever and malaise are rare but may occur during severe episodes
Diagnostic & Treatment
Diagnosis Path: Diagnosis of eosinophilic cellulitis involves a combination of clinical evaluation and laboratory tests. A healthcare provider typically performs a physical examination and considers the patient’s medical history. Skin biopsy is a crucial diagnostic tool, revealing characteristic features such as eosinophil infiltration in the skin tissue. Blood tests may show elevated eosinophil counts and other signs of inflammation. Differential diagnosis often includes bacterial cellulitis, allergic reactions, and other dermatological conditions, necessitating laboratory and histological analysis for confirmation.
Treatment Protocols: Treatment strategies for Wells syndrome aim to reduce inflammation and control immune responses. Common approaches include:
