Nummular Eczema (Discoid Eczema): How to Tell It Apart From Ringworm | Dermatologist Explains
Could that round, itchy rash really be ringworm... or is it actually nummular eczema (discoid eczema)? In this video, board-certified dermatologist Dr. Dray explains one of the most commonly misdiagnosed types of eczema, why it develops, what causes flare-ups, how to distinguish it from fungal infections like ringworm, and the most effective treatments to calm the itch and restore the skin barrier.
Learn why these coin-shaped patches appear, why they often worsen during the winter months, how dry skin, skin injuries, contact allergies, and bacterial infections can trigger nummular eczema, and what you can do to help prevent future flare-ups.
If you've been struggling with a persistent circular rash that won't go away, this video will help you understand when it might be eczema instead of a fungal infection and why getting the correct diagnosis matters.
