Overview
What this pattern can mean.
DermAI does not diagnose.
The product provides wellness information, probability estimates, and urgency guidance. Seek qualified medical care for diagnosis, treatment, rapidly changing symptoms, severe pain, fever, bleeding, infection signs, or any urgent concern.
Ringworm is caused by fungi, not worms. The classic pattern is an itchy, scaly ring with a clearer center, but not every scan looks textbook. Early lesions, treated lesions, scalp involvement, darker skin tones, and steroid use can make the pattern less obvious.
DermAI should keep ringworm in mind when there is a circular or expanding scaly border, exposure to pets or contact sports, or similar patches in household members. The result should be careful because psoriasis, eczema, contact dermatitis, and tinea versicolor can overlap visually.
Visible cues
- Circular or ring-shaped patch with scale, itch, and an active edge.
- Possible central clearing or expanding border.
- May involve body, groin, feet, scalp, beard area, or nails.
- Can spread through close contact, shared items, pets, gyms, or sports.
What DermAI checks
- Looks for annular shape, border activity, scale distribution, and central clearing.
- Uses notes about pets, sports, shared towels, recurrence, and steroid cream use.
- Escalates scalp, nail, face, widespread, or child cases toward clinical care.
Next steps
- Avoid sharing towels, clothing, razors, or sports gear while the rash is active.
- Do not use steroid creams on an undiagnosed ring-shaped rash unless a clinician advises it.
- See a clinician if the patch is on the scalp, beard, nails, face, widespread, recurrent, or not improving.
When to seek care
- Scalp, beard, nail, face, infant, or widespread involvement.
- Pain, swelling, pus, fever, or rapidly spreading rash.
- No improvement after appropriate antifungal care or repeated recurrence.
Choose urgent medical care over an app workflow for severe pain, rapidly spreading symptoms, fever, breathing difficulty, eye involvement, deep wounds, significant swelling, or anything that feels unsafe.
Safe self-care framing
- Keep the area clean and dry.
- Wash clothing, towels, and bedding regularly.
- Check pets or close contacts if patches keep returning.
