Dermoscopy - Introduction, Terminology and Structures
A document to help you understand the dermoscopic descriptions used in this blog.
Dermoscopy Algorithm
To help you work through dermoscopic cases.
This lesion was picked up by chance on a patient's trunk. Clinically it was fairly symmetrical, but what do you think about the dermoscopic features?
The key features are:
- Asymmetry of dermoscopic features
- An eccentric structureless zone (black circle)
- An atypical white network (black arrow) - the same as an atypical pigment network but white rather than brown/black. The metaphorical terminology for a white network is an inverse pigment network or negative pigment network
As you will see in the attached algorithm, asymmetry + an atypical white network (or eccentric structureless zone) is suspicious.
The diagnosis was a superficial spreading melanoma.
