What Is a White Skin Lesion
A white skin lesion is simply an area of skin that looks lighter than the surrounding tissue. Dermatologists break lesions into two big families: primary (the original change) and secondary (changes that happen because of scratching, infection, or other factors). Knowing that split helps you understand why a spot might look different over time.
Below is a quick visual guide you can picture in your head (or pull up a gallery for actual skin lesions pictures):
- Vitiligo sharp, depigmented patches, often on hands or face.
- Fungal white patch (tinea versicolor) slightly raised, sometimes a bit pinkish.
- Pityriasis alba faint, dry, round spots common in kids.
- Early basalcell carcinoma pearly, slightly raised white nodule.
One time a friend of minelets call her Mayathought a tiny white speck on her cheek was a scar from a childhood fall. Turns out, it was pityriasis alba, and a quick moisturizer routine made it fade away in weeks. Stories like that remind us how easy it is to misread our own skin.
