Nummular Eczema
Nummular eczema presents as coin-shaped, sharply bordered and itchy round plaques on the skin, arising on a background of marked dryness and a damaged barrier.

Tap to enlargeDo you recognise these signs?
If one or more of these applies to you, we recommend a dermatological assessment.
- Coin-shaped, round and sharply bordered plaques on the legs, arms and trunk
- Itching, weeping and crusting over the plaques, later giving way to dry scaling
- Marked dryness of the surrounding skin, with complaints rising in cold weather
- A tendency toward secondary infection and yellow crusting with scratching
Causes and triggers
- Severe skin dryness and an impaired barrier setting the stage for plaques
- Low winter humidity, hot showers and harsh soaps acting as triggers
- Insect bites, minor wounds and local irritation serving as a starting point
- A recurring course flared by contact allergens and by stress
How we treat it
Intensive moisturising and ceramide barrier repair to correct the dry background
Cortisone-free control: calcineurin and PDE-4 inhibitors applied to the plaques
Assessment for infection where there is weeping or crust, plus gentle cleansing
NB-UVB phototherapy for widespread stubborn disease and patch testing when indicated
Why Clinovia?
Psoriasis and eczema are not only a surface problem. We assess the skin barrier, inflammation, nutrition and lifestyle, comorbidities and dermatological treatment together. Evidence-based dermatology remains the backbone; nutrition and lifestyle support that plan.
The Gut–Skin Relationship
We review digestive symptoms, dietary pattern and food-sensitivity history. The link between gut microbiome and inflammatory skin disease is still being researched, so it is addressed alongside — never instead of — dermatological treatment.
Cortisone-Free Protocol
First-line calcineurin and PDE-4 inhibitors, ceramide-based barrier repair and phototherapy instead of steroids; systemic and biologic steps when needed.
Systemic Repair
Vitamin D, zinc, omega-3 and iron levels plus thyroid and insulin resistance are screened, and any deficits found are built into the plan.
Measurable Follow-up
PASI/EASI and DLQI scores are tracked alongside laboratory values; steps that do not deliver a response are removed from the plan.
Nummular means coin-shaped in Latin, and these round, sharply bordered plaques are the condition's hallmark. Why it takes this exact shape is not fully known, but severe dryness and barrier damage are thought to spark inflammation in small, discrete foci. Because it can mimic fungal disease, telling them apart matters.
Nummular eczema plaques can look ring-like and be confused with a true fungal infection. To separate them we use the edge pattern, the itch behaviour and, when needed, a simple fungal check. An accurate diagnosis avoids needless antifungal use and lets us start barrier-focused treatment quickly.
Yes. For infant eczema and paediatric psoriasis we use age-appropriate topical stepping, a moisturising routine and, when indicated, paediatric phototherapy dosing.
Our standard protocols are cortisone-free. We work with topical calcineurin inhibitors, PDE-4 inhibitors, ceramide-based barrier repair, NB-UVB phototherapy and biologic agents when needed. Cortisone is considered only for very short, unavoidable situations and with the patient's consent.
Other conditions
Atopic DermatitisAtopic dermatitis is a chronic form of eczema in which a weakened skin barrier drives itch and redness; it runs in flares and remissions and often settles in the body's flexures.

Contact EczemaContact eczema is inflammation triggered when a substance touching the skin acts as an allergen or irritant; it appears as sharply bordered redness and itch at the site of contact.

Seborrheic DermatitisSeborrhoeic dermatitis is a chronic reaction to Malassezia yeast in oil-rich areas, causing flaking and redness across the scalp, brows and the folds of the face.

NB-UVB PhototherapyNarrowband UVB at 311 nm calms inflammation in psoriasis and eczema without cortisone. Sessions run two to three times a week, with a typical course of 20–30 and PASI/EASI tracking.

Biologic TreatmentsBiologic drugs selectively block targets such as IL-17 and IL-23 in psoriasis and IL-4/13 in eczema. They are considered in moderate-to-severe, resistant disease after screening.
