I first described pigment bands in 2016 describing them as 'broader than lines, and can only be diagnosed in the absence of a network or other features of a melanocytic lesion. The bands, of variable length and width, are linear irregular or curved, and can be intertwined. Bands are commonly yellow or brown, but can be black'.
The image shows multiple bands (black arrows), some of which are arranged in curved patterns (blue circles).
Pigment bands are seen in thin, flat-topped seborrhoeic keratoses, if these lesions thicken the bands become less obvious as they take on the pattern of fissures and ridges.
For more information on dermoscopic patterns please refer to the adjacent document 'Dermoscopy - Introduction, terminology and structures'.
