<\/span>Who gets discoid eczema?<\/span><\/h2>\nDiscoid eczema can affect children and adults. It is slightly more common in adult men than in women. In men older than 50 years, there is an association with chronic<\/span> alcoholism.<\/p>\nDiscoid eczema can occur in atopic<\/span> eczema, eczema craquel\u00e9 and secondary eczematization.<\/p>\n<\/span>What are the clinical features of discoid eczema?<\/span><\/h2>\nThere are two forms of discoid eczema:<\/p>\n
\n- exudative acute<\/span> discoid eczema: oozy papules<\/span>, blisters and plaques<\/li>\n
- Dry discoid eczema: subacute or chronic erythematous<\/span>dry plates<\/li>\n<\/ul>\n
Both forms of discoid eczema usually affect the extremities rather than the trunk, but the eruption<\/span> maybe extended<\/span>. Although often bilateral<\/span>, the distribution<\/span> It is often asymmetric<\/span>.<\/p>\nIndividual plates are ok circumscribed<\/span>, mostly 1\u20133 cm in diameter, and swollen. Most patches are round or oval, hence the name "discoid" or "numular" (coin-shaped). Plaques are usually very itchy, but sometimes they don't itch at all. The skin between the patches is usually normal, but may be dry and irritable.<\/p>\nSevere discoid eczema can be generalized, with numerous small and large itchy lesions appearing all over the body due to an autoeczematization reaction.<\/p>\n
The patches can be lightened without leaving a sign<\/span>. However, on darker skin, the marks can persist for months. These can be dark brown (post-inflammatory<\/span> hyperpigmentation<\/span>) or paler than the surrounding skin (post-inflammatory hypopigmentation<\/span>)<\/p>\n\n<\/span>exudative discoid eczema<\/span><\/h5>\n<\/section>\n\n\n

<\/span>How is discoid eczema diagnosed?<\/span><\/h2>\nIn most cases, the appearance of discoid eczema is quite characteristic.<\/p>\n
\n- \nBacterial<\/span> swabs can reveal Staphylococcus aureus<\/em> colonization or infection.<\/li>\n
- Scrapings are commonly taken for mycology, as discoid eczema can be very similar to tinea corporis (ringworm infection).<\/li>\n
- \nPatch<\/span> tests are sometimes done to see if there might be a contact allergy<\/span> responsible for dermatitis. In most cases, a specific allergy cannot be found.<\/li>\n<\/ul>\n

<\/span>What is the treatment for discoid eczema?<\/span><\/h2>\nAs discoid eczema is associated with loss of skin barrier function, it is important to:<\/p>\n

As this type of dermatitis often begins as minor skin lesions, protect all of your skin carefully. If hands are affected, use gloves and tools to ensure skin is not irritated by friction, detergents, solvents, other chemicals, or excessive water.<\/p>\nApply emollients<\/span> frequently<\/strong>
Emollients include bath oils, soap substitutes, and moisturizers. They can be applied to dermatitis as often as needed to relieve itching, climbing<\/span> and dryness. Emollients should also be used on unaffected skin to reduce dryness. It may be necessary to try several different products to find one that suits you. Many people find one or more of the following helpful: glycerin and cetomacrogol cream<\/span>, white soft paraffin \/ mixed liquid paraffin, fat cream, wool fat lotions.<\/p>\nAnti-inflammatory<\/span> treatments include:<\/p>\nCurrent<\/span> steroids<\/strong>
Topical steroids are anti-inflammatory<\/span> creams or ointments available by prescription that can clear dermatitis and reduce irritation. The strongest products are applied to the patches only once or twice a day for 2 to 4 weeks. They repeat from time to time. Mild ones like hydrocortisone are safe for daily use if needed.<\/p>\nAntibiotics<\/strong>
Antibiotics (most often flucloxacillin) are often prescribed if the dermatitis is blistering, sticky, or crusty. Sometimes discoid eczema clears up completely with oral antibiotics, only to recur when they are stopped.<\/p>\nOther treatments sometimes prescribed for severe discoid eczema include:<\/p>\n
Oral antihistamines<\/strong>
Antihistamine pills can reduce itching in some patients with discoid eczema. They do not lighten the rash. <\/p>\nUltraviolet radiation<\/span> (UV<\/span>) treatment<\/strong>
Phototherapy several times a week for 6 to 12 weeks can reduce the extent and severity of discoid eczema.<\/p>\nsteroid injections<\/strong>
Intralesional steroids are sometimes injected into one or two particularly difficult areas of discoid eczema. This treatment is not suitable for multiple injuries.<\/p>\noral steroids<\/strong>
Systemic<\/span> Steroids are reserved for severe and extensive cases of discoid eczema. They are usually prescribed for a few weeks while continuing steroid creams and emollients in residual dermatitis.<\/p>\nOther oral treatments <\/strong>
Persistent and troublesome discoid eczema is occasionally treated with methotrexate, azathioprine, or cyclosporine. These medications have significant risks and side effects and require careful monitoring by a specialist. dermatologist<\/span>. They may be more suitable in many cases than steroids in the long term.<\/p>\nDiscoid eczema can usually be controlled with the above measures, although it tends to recur when treatment is stopped.
