The diagnosis of eczema primarily relies on clinical symptom observation and detailed medical history analysis. Medical professionals confirm the diagnosis through a multifaceted evaluation. The diagnostic process typically includes skin examination, symptom tracking, and ruling out other similar diseases. Early diagnosis can effectively prevent symptom worsening and develop a personalized treatment plan.
The diagnosis of eczema is not determined by a single indicator but is a process that integrates multiple clinical information. Physicians pay special attention to core symptoms such as skin redness, itching, and dryness, combined with key information like the patient's allergy history and family medical history. In certain cases, further laboratory tests or special examinations may be required to exclude other skin diseases.
When diagnosing eczema, physicians first gather information about the patient's symptom development process through questioning. This includes the onset time of symptoms, changes in severity, triggering factors (such as climate changes or contact with specific chemicals), and whether there are accompanying allergic-related diseases (such as asthma or allergic rhinitis).
Skin examination is a core step in the diagnosis. Physicians carefully observe the distribution and morphological characteristics of skin lesions, such as erythema, scales, or lichenification in common affected areas like the bends of the elbows and the backs of the knees. Chronic lesions may present with skin thickening and pigmentation, which help differentiate from other skin diseases.
When clinical manifestations are unclear, physicians may arrange auxiliary examinations to confirm the diagnosis. Skin biopsy can observe tissue changes, such as epidermal thickening and inflammatory cell infiltration in the dermis. This examination is particularly applicable for chronic or recurrent cases.
Standardized assessment tools can quantify the severity of eczema and treatment effects. The SCORAD index (SCORing Atopic Dermatitis) scores based on the area affected, severity, and intensity of symptoms, with a score range of 0-103, where a higher score indicates more severe conditions.
For pediatric patients, the Eczema Area and Severity Index (EASI) assessment system is commonly used, evaluating indicators such as erythema, itching, and scaling in four main areas (head and neck, upper body, lower body, and limbs). These tools are used not only for diagnosis but also for tracking treatment progress.
The symptoms of eczema have a high similarity to other skin diseases, requiring careful differentiation. For example, atopic dermatitis often needs to be distinguished from contact dermatitis, which is usually limited to areas that have come into contact with allergens. The scaly red plaques of psoriasis are distinctly different from the itchy dry skin of eczema, but chronic cases may exhibit mixed features.
Fungal infections such as tinea may present with round red patches and scaling, requiring skin scraping tests to confirm the presence of fungi. Seborrheic dermatitis commonly occurs in areas with sebaceous gland distribution, while eczema often affects flexural areas; these anatomical distribution differences are key to differentiation.
Early diagnosis allows for prompt symptom management, preventing secondary infections or chronic skin thickening caused by scratching. If pediatric patients are not treated early, prolonged itching may affect sleep quality and daily functioning, and early intervention can improve quality of life.
Identifying high-risk patients early (such as those with a positive family allergy history) can implement preventive skin care to reduce the frequency of acute episodes. Studies show that early use of moisturizers and topical corticosteroids can decrease the likelihood of disease progression, demonstrating the clinical value of early diagnosis.
The diagnosis of eczema (atopic dermatitis) typically requires combining symptoms, family history, and skin examination. Physicians will observe whether symptoms present with recurrent itching, dry erythema, and are concentrated in flexural areas (such as the elbow creases and knee pits). If skin diseases similar to eczema (such as contact dermatitis or xerosis) are difficult to distinguish, allergen testing or skin biopsy may be necessary to rule out other causes.
What are the key steps in daily skin care after a diagnosis of eczema?Daily care after diagnosis is crucial for controlling symptoms. It is recommended to use fragrance-free moisturizers daily to strengthen the skin barrier, avoid hot water during baths, and refrain from scratching. Additionally, it is important to identify personal triggering factors (such as dust mites and pollen) and choose breathable materials for clothing to reduce friction and lower the frequency of flare-ups.
How does allergen testing help in the treatment of eczema?Allergen testing (such as skin prick tests or blood IgE tests) can help identify potential allergens that may trigger eczema exacerbations, but not all patients need to undergo this. If symptoms are related to specific allergens (such as food or environmental allergens), avoiding these factors can effectively reduce flare-ups. However, a negative result for allergens does not mean treatment is unnecessary, as the causes of eczema are complex and require an overall assessment of the situation.
Can the use of steroid ointments lead to skin thinning or side effects?Topical corticosteroid ointments are first-line medications for treating eczema and are generally safe when used correctly. Short-term use as directed usually does not lead to skin atrophy, but long-term high-dose use may cause side effects. Therefore, physicians will choose the appropriate strength of ointment based on the severity of symptoms and recommend alternating with non-steroidal medications (such as calcineurin inhibitors) to reduce risks.
Why do eczema symptoms vary significantly across different seasons?Eczema is prone to flare-ups due to environmental dryness or temperature changes. In winter, low humidity and frequent indoor heating can exacerbate skin dehydration and worsen symptoms; in summer, sweating or contact with allergens (such as pollen) can lead to exacerbation. Physicians will recommend adjusting care methods according to the season, such as increasing moisturizing frequency in winter and avoiding prolonged sun exposure in summer.
