<p>I first described <strong>pigment bands</strong> 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'. </p>
<p>The image shows multiple bands (black arrows), some of which are arranged in curved patterns (blue circles).</p>
<p><strong>Pigment bands are seen in thin, flat-topped seborrhoeic keratoses</strong>, if these lesions thicken the bands become less obvious as they take on the pattern of fissures and ridges.</p>
