Dr. Mathieu Powell, MD on Instagram: "I’m blue… nevus. 🩵🎶 #dabadee Not all that’s blue is bad news 😮‍💨 🔬 Dermoscopy clues: • Structureless, homogeneous blue to gray pigmentation • No network, dots, or globules • Sharp borders, often symmetric • No vessels — just smooth blue calm 💡 The color comes from the Tyndall effect — light scattering off melanin deep in the dermis. 🚩 Watch out if: • The blue area shows new growth, asymmetry, or multiple colors — could hint at melanoma or regression.
