We explain things using as little difficult medical jargon as possible. Do you have problems like: "Round, intensely itchy eczema on your legs or arms that won't go away" "I scratched it open and it spread even further"? This time, we'll be discussing in detail about nummular eczema, a condition named for its distinctive shape. Please watch until the end! 👀👉 📌 Contents of this video 0:00 Introduction 0:22 Main content 1:05 Symptoms 2:18 Causes 3:57 Commercial 4:17 Prevention 5:44 Treatment 8:13 Differential Diagnosis 9:51 Summary 10:43 Notice 📍Symptoms As the name suggests, this disease is characterized by multiple circular eczema lesions resembling 10-yen or 500-yen coins. The eczema is typically reddish to brownish with clearly defined borders. 🔴🟤 Small blisters may form on the surface, and there may be oozing or oozing fluid, which then dries into scabs. The itchiness is extremely intense and often unbearable, and scratching can easily lead to a vicious cycle where the eczema spreads further, so caution is necessary. 💥🔄 🦠 Causes The main trigger is "dry skin." Nummular eczema often develops when aging or dry winter skin is severely scratched. 🏜️💨 People with atopic dermatitis, allergies (especially metal allergies), and the elderly are said to be more prone to nummular eczema. Those with cavities, tonsillitis, sinusitis, chronic rhinosinusitis, and inflammation are also more susceptible. 🩺💡 🛡️ Prevention The most important point is to "keep your skin moisturized." When you visit the clinic, we will prescribe Hirudoid, Urepearl, or Vaseline. Apply moisturizer twice a day, in the morning and after bathing. 🧴💧 When bathing, set the water temperature to lukewarm (around 38-40°C) and gently wash with your hands or a soft towel, avoiding scrubbing with nylon towels. Since nummular eczema is often triggered by dryness, insect bites, or rashes, address it early to prevent it from progressing. 🌿🦟 💉Treatment In the early stages of nummular eczema, most cases improve within 2-3 weeks with the use of topical steroid creams. 💊⏳ If itching is present, antihistamines or anti-allergic medications such as Allegra or Desloratadine may be prescribed. If left untreated, it can cause itching in areas that weren't itchy before, potentially leading to autosensitization dermatitis (autosensitization eczema) with nummular eczema all over the body. 🌀💥 Visit a dermatologist as soon as you notice one or two nummular eczema lesions. ⏰🏥 🔎 Differential Diagnosis Athlete's foot (tinea corporis), pityriasis rosea, psoriasis, and syphilis can all present with similar symptoms, so get tested early rather than self-diagnosing. 🔬🧪 If it's difficult to treat, treatments such as ultraviolet therapy or Dupixent (a biological agent) may be used. 🚀 Summary This troublesome eczema is prone to severe itching and recurrence, but with the right knowledge and care, it can be effectively treated.
