  Discoid eczema is a fairly common type of eczema, seen in people with and without a history of atopic eczema. […] See your GP for a diagnosis (and treatment) if you think you may have discoid eczema. Other skin conditions, such as ringworm (fungal infections) and psoriasis can look similar. […] It is unusual for fungal infections to manifest as scattered patches over the body, like discoid eczema. […] There are also some very rare skin conditions that may look like discoid eczema, so always confirm the diagnosis with your healthcare professional.

  Discoid eczema is a subtype of nonatopic eczema defined by circular or oval plaques of eczema with a well-demarcated edge. […] The diagnostic lesion is a coin-shaped plaque of closely-set thin-walled scaling and vesicles on a scaly erythematous base, classically on the extensor surfaces of lower limbs. […] Differentiating discoid eczema from other forms of dermatitis is important for optimal management, particularly in avoiding triggers. […] Discoid eczema is a clinical diagnosis. […] However, exogenous contact dermatitis should be suspected if the condition is unusually severe and persistent, or if the lesions are few, asymmetrical or of unusual configuration. […] In these cases, patch testing can be performed. […] Although discoid eczema does not generally require a biopsy, histological examination demonstrates a subacute dermatitis, with spongiotic vesicles and lymphohistiocytic infiltrate. […] Referral to a dermatologist is appropriate if the disease does not respond to conservative skin care measures, bland emollients, topical corticosteroids and antibiotics.

  https://www.pcds.org.uk/clinical-guidance/eczema-discoid-syn-nummular-eczema

  The term discoid eczema comes from its characteristic round or oval 'disc-shaped’ patches. For the same reason it is sometimes also called nummular eczema – nummular meaning coin-shaped. The cause of discoid eczema is unknown. […] Age – most commonly presents in middle-aged patients, but can affect any age group. […] Can be associated with excessive bathing or swimming. […] Discrete round / oval patches. […] Differs from psoriasis in that lesions tend to be a lighter red, the border fades gradually at the periphery and they may have an exudate / crust as opposed to scale. […] Acute treatment – short-term use of a potent topical steroid, eg 0.1% betamethasone cream OD until things settle. […] Long-term treatment – regular use of a topical emollient (prescribe 500 g), at least twice a day, with the same topical steroid reintroduced for a flare. The more emollient used, the less the skin will flare, limiting the use of topical steroids.

  https://nyulangone.org/conditions/eczema-dermatitis/diagnosis

  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. […] This allergy test is uniquely designed to identify the cause of contact dermatitis without using needles. The patch test remains the only reliable method of determining which substances cause an allergic reaction when they come into contact with the skin. […] If dermatologists suspect that allergic dermatitis is causing your rash, a patch test is the most effective diagnostic tool. […] A doctor may not record the final results for up to four days to allow for delayed reactions. On the final reading, our doctors conduct an examination to match signs of reaction on the skin with the substance that was placed there. 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.
