Dermoscopy Algorithm
To help you work through dermoscopic cases.
<p>The predominant central features are <strong>white structureless areas </strong>(blue arrows), and the predominant peripheral feature is a <strong>brown rounded network </strong>(black arrows). The diagnosis is a dermatofibroma.</p>
<p>Dermatofibromas can often be diagnosed clinically as a firm smooth lump that can be palpated under the skin surface, lesions often dimple in the centre when squeezed.</p>
<p>Dermoscopically please refer to the algorithm. Most lesions have a central white component, unless they are flat in which case such a finding may be absent. The peripheral brown rounded network can be very subtle.</p>
