(b) Dermoscopic imaging of a patient with an advanced lesion of necrobiosis lipoidica, showing elongated, branching, and focused serpentine vessels. (c) and (d) Low magnification (10X) dermoscopic images taken of two different nailfolds. (e) and (f) High magnification (300X) videocapillaroscopic images correlating with (c) and (d), respectively. (c) and (e) were taken of a patient with primary Raynaud’s phenomenon and show normal hairpin capillary loops, while (d) and (f) were taken of a patient with systemic sclerosis and show widened loops, avascularity, and haemorrhage.
