⚠️ Not a diagnostic tool. This is an educational illustration of how the ABCDE mnemonic combines five features into a simple composite score. It cannot diagnose skin cancer. Any real lesion of concern needs an in-person dermatologist exam.
Drag the sliders to model how each ABCDE feature reshapes the illustrative lesion and risk band

🩺 Skin Lesion ABCDE Risk-Score Simulator

This simulator turns the classic ABCDE dermatology screening mnemonic, Asymmetry, Border irregularity, Color variegation, Diameter and Evolution, into five live controls that reshape a procedurally-drawn lesion on canvas and feed a clearly-labeled illustrative composite risk band, mirroring the kind of simple feature engineering that predates deep-learning classifiers trained on datasets like the ISIC dermoscopy archive.

🔬 What It Demonstrates

This simulator turns the classic ABCDE dermatology screening mnemonic, Asymmetry, Border irregularity, Color variegation, Diameter and Evolution, into five live controls that reshape a procedurally-drawn lesion on canvas and feed a clearly-labeled illustrative composite risk band, mirroring the kind of simple feature engineering that predates deep-learning classifiers trained on datasets like the ISIC dermoscopy archive.

🎮 How to Use

Drag the asymmetry, border, color and diameter sliders to watch the lesion shape, blotching and size change in real time against a 6mm pencil-eraser reference circle, then flip the evolution toggle to see how a recent change shifts the illustrative risk band between Low, Moderate and High.

💡 Did You Know?

Did you know that ABCDE was designed as a quick visual screening heuristic for patients and primary-care clinicians, not a diagnostic algorithm, and that some melanomas, particularly nodular melanoma, fail to fit the "big, asymmetric, multicolored" pattern at all? Large annotated dermoscopy datasets like ISIC let deep-learning models learn far richer texture, color-gradient and border features than the five ABCDE letters can capture, which is part of why CNN classifiers have matched dermatologist-level accuracy on some narrow benchmark tasks.
