  https://www.mayoclinic.org/diseases-conditions/dermatitis-eczema/diagnosis-treatment/drc-20352386

  To diagnose dermatitis, your doctor will likely look at your skin and talk with you about your symptoms and medical history. You may need to have a small piece of skin removed for study in a lab, which helps rule out other conditions. This procedure is called a skin biopsy. […] Your doctor may suggest a patch test to identify the cause of your symptoms. In this test, small amounts of potential allergens are put on sticky patches. Then the patches are placed on your skin. They stay on your skin for 2 to 3 days. During this time, you’ll need to keep your back dry. Then your health care provider checks for skin reactions under the patches and determines whether further testing is needed. […] Explore Mayo Clinic studies testing new treatments, interventions and tests as a means to prevent, detect, treat or manage this condition.

  The different types of eczema and dermatitis can look and feel very similar on the skin. […] NYU Langone dermatologists, with their extensive experience and expertise, may differentiate between atopic, contact, and nummular dermatitis simply by examining the distribution of the rash on your skin and asking questions about your family and medical history. […] Our doctors have also been leaders in the diagnosis of contact dermatitis since the 1930s, when the patch test was brought to the United States and the technique was refined. […] The patch test remains the only reliable method of determining which substances cause an allergic reaction when they come into contact with the skin. […] A dermatologist carefully examines your skin during a physical exam. […] Knowing whether anyone else in your family has been diagnosed with eczema or dermatitis may help doctors better understand your diagnosis.

• #1 Dermatitis: Types and treatments — DermNet

  https://dermnetnz.org/topics/dermatitis

  Dermatitis refers to a group of itchy inflammatory conditions characterised by epidermal changes. […] Dermatitis can be classified in a variety of ways. […] The terms dermatitis and eczema are often used interchangeably. All eczema is a dermatitis, but not all dermatitis is eczema. […] Dermatitis is common, affecting about one in every five persons at some stage in their life. […] Different types of dermatitis are more frequent at different stages of life, for example: Atopic dermatitis and pityriasis alba are more common in children. […] Dermatitis may be either acute or chronic, and although the mechanism by which the dermatitis develops may be the same, the appearances may be starkly different. […] Exogenous dermatitis is the result of an external factor or insult that induces skin inflammation.

  https://www.aafp.org/pubs/afp/issues/2010/0801/p249.html

  Contact dermatitis is a common inflammatory skin condition characterized by erythematous and pruritic skin lesions that occur after contact with a foreign substance. […] When a possible causative substance is known, the first step in confirming the diagnosis is determining whether the problem resolves with avoidance of the substance. […] If treatment fails and the diagnosis or specific allergen remains unknown, patch testing should be performed. […] The diagnosis of contact dermatitis is most often made with history and physical examination findings. […] When a possible causative substance is known, the first step in confirming the diagnosis is observing whether the problem resolves with avoidance of the substance. […] If avoidance and empiric treatment do not resolve the dermatitis or the allergen remains unknown, patch testing may be indicated.

  You may first bring your concerns to the attention of your primary care provider. Or you may see a doctor who specializes in the diagnosis and treatment of skin conditions (dermatologist) or allergies (allergist). […] Your doctor is likely to ask you a few questions. Being ready to answer them may free up time to go over any points you want to spend more time on. Your doctor might ask: Do your symptoms come and go, or are they fairly constant? How often do you shower or bathe? What products do you use on your skin, including soaps, lotions and cosmetics? What household cleaning products do you use? Are you exposed to any possible irritants from your job or hobbies? Have you been under any unusual stress or depressed lately?

  Allergic contact dermatitis (ACD) is a type IV (delayed) hypersensitivity reaction that has a wide spectrum of presentations that often imitate or overlap with other cutaneous eruptions. […] Epicutaneous patch testing remains the gold standard for diagnosing ACD. […] For diagnosis and definitive treatment ACD must be considered within a broad differential diagnosis, but the differential can be narrowed with careful history taking and clues found on physical examination. […] The epicutaneous patch test remains the gold standard for diagnosing ACD. When positive patch test reactions are elicited, the potential relevance of the identified allergens to the dermatitis must be assessed. […] When the diagnosis is in doubt and patch testing does not identify the relevant allergens or allergen avoidance fails to clear the eruption, skin biopsy for histopathologic examination may be helpful in distinguishing ACD from other conditions.

  If dermatologists suspect that allergic dermatitis is causing your rash, a patch test is the most effective diagnostic tool. […] After two days, the panels are removed and a note is made of any areas of irritation. […] Redness with elevated skin or a rash at the site of any of the tested allergens may help your dermatologist determine the source of the allergic reaction and confirm a diagnosis of allergic dermatitis. […] At times, a dermatologist needs to remove a small piece of skin for lab testing. […] A skin biopsy is a minor procedure performed in a doctors office. […] In a lab, a pathologist who specializes in skin cells, called a dermatopathologist, examines the sample under a microscope to determine whether eczema or dermatitis is present or if a different skin condition accounts for the rash.

  https://practicingclinicians.com/the-exchange/contact-dermatitis-diagnosis-and-management-when-to-refer-for-patch-testing

  Contact Dermatitis Diagnosis and Management: When to Refer for Patch Testing […] Diagnosis of CD is often clinical and based on history and physical exam. […] If avoidance of the potential trigger and empiric treatment do not relieve symptoms, patch testing may be indicated. […] Patch testing attempts to recreate an allergic reaction to allergens to confirm or rule out potential triggers. […] One indication for patch testing includes patients with distributions that are highly suggestive of ACD, such as involvement of the hands, feet, face, or eyelids. […] If there is unilateral involvement, ACD should also be suspected, and therefore patch testing is indicated. […] Further, if a patient has a clinical history highly suggestive of ACD, patch testing should be performed. […] Patch testing should also be performed on patients that are in high-risk occupations for ACD, including healthcare workers, cosmetologists, and machinists.

• #1 Eczema Diagnosis | National Jewish Health

  https://www.nationaljewish.org/conditions/eczema/do-i-have-eczema

  Skin biopsy: In this procedure a doctor first numbs the skin and then removes one or more small pieces of skin, which is used to rule out other skin diseases from atopic dermatitis, such as a low-grade skin cancer or psoriasis. […] Allergy skin testing: If there is concern for an associated food allergy or environmental allergy, prick skin tests can be done to common foods or inhalant/animal allergens to show sensitization or lack of sensitization to specific allergens. […] Patch testing: In this test, small patches covered with allergenic chemicals are placed on the skin for 48 hours, then removed and the skin reaction is evaluated at 72-96 hours. […] Buccal swabs: The inside of the cheek can be swabbed with a cotton applicator to get cells as a source of DNA material to look for mutations in the Filaggrin gene, one of the causes of eczema.

• #1 Irritant Contact Dermatitis Workup: Approach Considerations, Laboratory Studies, Other Tests

  https://emedicine.medscape.com/article/1049353-workup

  The histopathology of acute experimental ICD has been studied more thoroughly than that of chronic ICD, which is the primary clinical complaint. Cellular changes seen in the skin vary according to the chemical nature and concentration of the irritant applied, the duration of exposure, the severity of the ensuing response, and the time of sampling for acute ICD. Many primary irritants cause overt necrosis if applied in a sufficiently high concentration for a sufficient time. […] Most histologic examinations of ICD reveal some degree of intercellular edema or spongiosis in the epidermis. Spongiosis usually is less pronounced than that seen in allergic contact dermatitis reactions. […] The histology of chronic ICD is one of hyperkeratosis with areas of parakeratosis, moderate-to-marked epidermal hyperplasia (acanthosis), and elongation of the rete ridges.

• #1 Irritant Contact Dermatitis Workup: Approach Considerations, Laboratory Studies, Other Tests

  https://emedicine.medscape.com/article/1049353-workup

  No single diagnostic test exists for irritant contact dermatitis (ICD). The diagnosis rests on the exclusion of other cutaneous diseases (especially allergic contact dermatitis) and on the clinical appearance of dermatitis at a site sufficiently exposed to a suspected or known cutaneous irritant. […] Laboratory studies are generally of little value in proving a diagnosis of contact dermatitis. However, they may be of value in eliminating some disorders from the differential diagnosis. […] Patch testing can be performed to diagnose contact allergies, but there is no patch test capable of proving that a cutaneous irritant is responsible for a particular case of ICD. Diagnosis rests on exclusion of allergic contact dermatitis and a history of sufficient exposure to a cutaneous irritant. […] Skin biopsy can help exclude other disorders, such as tinea, psoriasis, or cutaneous T-cell lymphoma.

  http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0256-95742014001000027

  The traditional criteria set out by Hanifin and Rajka are used less frequently than before. Williams et al. (UK Working Party) developed a revised set of criteria, which was validated in the hospital setting and in the community. According to this group, these criteria should be adopted for the diagnosis of AD, even though a recent study in children has shown that these criteria are not reliable when applied to low-prevalence populations, i.e. the amaXhosa in South Africa. […] The histological findings on skin biopsy may be suggestive of the diagnosis, but generally cannot be relied on to make the diagnosis. Total serum IgE levels are significantly raised in about 50% of cases and normal in the rest, reducing their value in the diagnosis. The IgE level does not correlate with the severity of the dermatitis, and 15% of non-atopic individuals have raised IgE levels. Several conditions have to be considered in the differential diagnosis of AD. These have to be excluded clinically and by appropriate investigations.

• #1 Atopic Dermatitis Diagnosis & Evaluation | Clinical Guidance

  https://www.healio.com/clinical-guidance/atopic-dermatitis/diagnosis-and-evaluation-diagnosis

  During diagnosis, AD should be differentiated from a variety of other causes of cutaneous inflammation. […] Biomarkers can be used for a variety of purposes, including confirmation of clinical diagnosis, objective measures of disease severity, and prediction of treatment response. However, there are currently no biomarkers that accurately reflect the severity of AD or its symptoms, or distinguish AD from other diseases. As such, the diagnosis and severity assessment of AD remains clinical. […] Elevated total and/or allergen-specific serum immunoglobulin E (IgE) is the most commonly considered biomarker with AD. Although total IgE does tend to increase with disease severity, many individuals with severe AD have normal IgE levels. […] There is no gold standard for evaluating the severity of AD. Since there are no reliable laboratory tests or biomarkers to assess the severity of AD, clinicians must rely upon clinical assessments of disease parameters that can be subjective and difficult to standardize.

  https://www.aafp.org/pubs/afp/issues/2020/0515/p590.html

  Atopic dermatitis is a clinical diagnosis with no definitive laboratory test. Approximately 80% of patients with atopic dermatitis are diagnosed and treated in the primary care setting. The American Academy of Dermatology (AAD) has streamlined the diagnosis using previously validated diagnostic criteria. The AAD criteria differentiate essential features that must be present for diagnosis, such as pruritus; important features that support the diagnosis, such as early age at onset; and associated features that suggest the diagnosis but are nonspecific, such as lichenification. […] The Scoring Atopic Dermatitis index is the most widely used validated clinical tool to classify atopic dermatitis severity based on the affected body area and intensity of lesion characteristics. Other validated tools include the Eczema Area and Severity Index; the Investigator Global Assessment scale; and the Six Area, Six Sign Atopic Dermatitis severity score.

  Atopic dermatitis (AD) is one of the most common inflammatory skin diseases affecting children and adults. […] This article provides an overview of AD, including strategies for differential diagnosis and assessment of disease severity to guide treatment selection. […] Clinical presentation and severity of AD varies widely, and diagnosis is not always straightforward, especially in adults. […] A diagnosis of AD is made on the basis of clinical presentation and history, with exclusion of multiple erythematous and eczematous conditions. Diagnosis is generally straightforward in infants and young children, but can be challenging in severe cases and in adults. […] Over the years, several sets of criteria have been developed to assist with the diagnosis of AD.

  Objective: To provide primary care providers an up-to-date approach to the diagnosis and management of atopic dermatitis (AD). […] Main Message: AD is a common chronic skin disease characterized by immune dysregulation and skin barrier dysfunction. It has a substantial impact on quality of life across all ages. Despite this, AD is often still undertreated due to inaccurate diagnoses, even by many experienced dermatologists. […] The most commonly used diagnostic criteria for AD include 4 components: (1) pruritus, (2) dermatitis in infant or adult distributions, (3) chronic or relapsing dermatitis, and (4) personal or family history of atopy. […] The presence of 3 major and 3 minor criteria are required for a definitive diagnosis of AD. […] The severity of AD is commonly categorized into mild-to-moderate AD involving limited areas of the body affected, milder intensity of pruritus, and sleep loss; and severe AD involving widespread areas of dry skin, high frequency of pruritus, and a significant impact on quality of life.

  Given the increasing number of outcome measures developed for AD, the Harmonizing Outcome Measures in Eczema (HOME) international consensus group was assembled to promote the standardization of use of AD outcome measures in clinical trials internationally. […] The SCORAD was inaugurated in 1993 by the European Task Force on AD, and is the most commonly used objective assessment in RCTs for AD. […] The Eczema Area and Severity Index (EASI) was developed as a modification of the well-established Psoriasis Area and Severity Index (PASI). […] The modified EASI (mEASI) is a variant of EASI that is identical but includes an assessment of itch by the patient. […] The DLQI tool, developed in 1994, is one of the most commonly used assessments in dermatology and clinical trials. […] The POEM, developed in 2004, was designed as a patient-reported outcome to measure frequency of AD activity.

  Assessment of disease severity is a guideline-recommended first step in treatment selection and valuable for monitoring treatment response. […] Numerous tools have been developed for severity assessment; these are summarized in Table III. […] Treatment of AD follows a multifaceted, stepwise approach that is tailored according to disease severity. […] Proper diagnosis that excludes conditions with similar skin manifestations, together with assessment of AD severity, is crucial to selecting appropriate treatment and achieving control of the intense itch and rash that can disrupt sleep, contribute to depression and anxiety, and impair QOL.

• #1 Guidelines for the diagnosis and assessment of eczema

  https://dermnetnz.org/topics/guidelines-for-the-diagnosis-and-assessment-of-eczema

  Eczema is a chronic inflammatory skin disease that affects about 20% of children and 3% of adults. It is characterized by pruritus, scratching, and eczematous lesions (dry, scaling and crusted areas of skin), and when chronic may be associated with lichenification (thickening) and pigmentary changes. It follows a relapsing course with flares at varying frequency and periods of remission. Eczema is also known as atopic eczema, or atopic dermatitis (eczema). […] The diagnosis of eczema is based on patient history and clinical/physical examination. Features to consider when making a diagnosis are summarized in the following tables. […] The diagnosis of eczema depends on excluding other skin conditions that may show similar features. Other diagnoses should be considered particularly when there is an atypical presentation, associated failure to thrive or inadequate response to treatment. […] In some instances investigations may be needed to confirm the diagnosis of eczema and rule out other diagnoses.

  The common differential for AD includes seborrheic dermatitis, irritant contact dermatitis, allergic contact dermatitis, plaque psoriasis, and scabies infestation. […] Patch testing can be helpful to confirm the diagnosis of allergic contact dermatitis. […] The management of AD should involve the liberal use of emollients and an avoidance of common irritants. In mild-to-moderate AD, TCS are the first-line medical therapy, followed by calcineurin inhibitors, which have been shown to be noninferior to TCS in controlling AD, without the risk of steroid atrophy. […] Topical corticosteroids (TCS) are the first-line medication for controlling mild-to-moderate AD. Proper use involves considering both the potency of TCS and lesion location. […] If no effects are seen after 2 weeks, clinicians should consider alternative potencies or medications or consider another diagnosis.

  https://www.hcplive.com/view/the-diagnosis-of-atopic-dermatitis

  At the outset, Melodie Young, NP, emphasizes the clinical nature of atopic dermatitis (AD), highlighting the Hanifin and Rajka diagnostic criteria. To confirm a diagnosis, at least 3 main features pruritus, typical morphology, and distribution are required, with additional considerations such as chronic relapsing dermatitis and a history of atopy. […] Andrea Nguyen, PA, discusses the diverse presentation of AD, emphasizing variations between adult and pediatric patients. The diagnostic criteria include major features like flexor lichenification and extensor eruptions in adults, and facial and extensor surface involvement in pediatric cases. Minor criteria, from erythema to elevated serum IgE (allergen-specific immunoglobulin E) levels, further contribute to a comprehensive diagnosis. […] The hosts stress the importance of considering the evolving nature of AD, often lacking abrupt onset and manifesting as a persistent condition. This program offers valuable insights into optimizing care, with a focus on approved agents, clinical trial data, and the crucial role of advanced practice providers in tailoring treatment for individuals with AD.

  http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0256-95742014001000027

  Atopic dermatitis (AD) is essentially diagnosed clinically. In babies and young children, the diagnosis is usually straightforward. Dry, very pruritic dermatitis starts on the cheeks, with the neck and trunk often involved, but the nappy area spared. Limb involvement follows later – first extensoral, later classically flexural. This is mostly the picture of AD. In adults, the presentation may vary widely. Classic flexural dermatitis may persist, but erythroderma (whole-body involvement), head and neck dermatitis, isolated hand dermatitis and nummular dermatitis may be more difficult to identify as AD. […] The diagnosis of atopic dermatitis (AD) is often not straightforward, especially in adults. Young babies who present with typically dry pruritic dermatitis in the classic distribution according to the age of the child are easy to diagnose. Several other conditions have to be considered in the differential diagnosis, as discussed below. Where the disease represents a mere continuation of AD since childhood, the diagnosis is usually easy and the clinical picture typical. With onset 18 years of age (adult-onset AD), the disease pattern is often not obvious, although it may still present with the usual flexural dermatitis seen in children. Non-typical morphological features and localisation are common with nummular, prurigo-like, follicular and seborrhoeic patterns that are often seen. In adults, erythroderma is a rare manifestation of AD. The physical and environmental factors for adults differ from those for children and are responsible for the different patterns of involvement.

• #2 Irritant Contact Dermatitis Workup: Approach Considerations, Laboratory Studies, Other Tests

  https://emedicine.medscape.com/article/1049353-workup

  The histopathology of acute experimental ICD has been studied more thoroughly than that of chronic ICD, which is the primary clinical complaint. Cellular changes seen in the skin vary according to the chemical nature and concentration of the irritant applied, the duration of exposure, the severity of the ensuing response, and the time of sampling for acute ICD. Many primary irritants cause overt necrosis if applied in a sufficiently high concentration for a sufficient time. […] Most histologic examinations of ICD reveal some degree of intercellular edema or spongiosis in the epidermis. Spongiosis usually is less pronounced than that seen in allergic contact dermatitis reactions. […] The histology of chronic ICD is one of hyperkeratosis with areas of parakeratosis, moderate-to-marked epidermal hyperplasia (acanthosis), and elongation of the rete ridges.

  Allergy testing by intradermal versus allergen-specific IgE serum testing. […] Use of any one of these approaches in isolation can result in misdiagnosis, so it is important not to rely on any of them as a sole diagnostic principle. […] Once steps 1-4 of the diagnostic work-up has been completed, a clinical diagnosis of canine AD should be considered if the pruritus is still present. […] Allergy tests should only be used once a clinical diagnosis of canine AD has been made with the primary purpose being to identify potential causative allergens that may be avoided or treated with ASIT. […] Both testing methods are very different and not standardized, which inevitably results in poor correlation between both tests. […] The appropriate selection of allergens to test is fundamental to obtain reliable IDT results. […] The results of these tests are also used to identify the offending allergen(s) in order to formulate an allergen-specific immunotherapy (ASIT).

• #2 Atopic Dermatitis Diagnosis & Evaluation | Clinical Guidance

  https://www.healio.com/clinical-guidance/atopic-dermatitis/diagnosis-and-evaluation-diagnosis

  The 1980 Hanifin and Rajka criteria are the original and most commonly employed diagnostic criteria for AD. A diagnosis of AD under the Hanifin and Rajka criteria requires that patients meet three of four major criteria and three of 23 minor criteria. Although comprehensive and used commonly in clinical trials, these criteria may not be practical in clinical practice for several reasons: 1) the large number of criteria are cumbersome, 2) some criteria are nonspecific, such as pityriasis alba; and 3) other criteria are uncommon in AD despite being fairly specific, such as upper lip cheilitis. As such, several groups have proposed modifications to address these limitations. […] The UK Working Party simplified the Hanifin and Rajka criteria, requiring patients to meet a single mandatory condition (i.e., itchy skin condition) plus three of five minor criteria. No laboratory testing is required, making these criteria better suited for epidemiologic and population-based studies, in addition to clinical practice. Both the Hanifin and Rajka criteria and UK criteria have been validated in studies and in a range of populations. Although revisions have been proposed to include infants, the original UK criteria cannot be applied to very young children.
