❌ What It’s NOT
Not vitiligo: Vitiligo spots are larger, irregular, and often symmetrical (e.g., both hands). IGH spots are small and scattered.
Not fungal: No itching, scaling, or redness.
Not cancerous: These spots are completely benign.
🩺 When to See a Doctor
While IGH is harmless, consult a dermatologist if the spots are:
Itchy, scaly, or growing rapidly
Changing color or shape
Appearing in unusual places (like the mouth or genitals)
Accompanied by other symptoms (fatigue, hair loss, etc.)
A doctor can confirm the diagnosis with a simple visual exam or Wood’s lamp (a special UV light).
