Figure 2: (a) Dermoscopy of erythema dyschromicum perstans reveals bluish-gray globules (red arrows) in a bizarre and irregular arrangement referred as “speckled” appearance. Globules are dull as they are situated in deeper dermis. Note the meager amount of brown (yellow arrows) and brownish-gray globules on bluish-gray background. (b) Dermoscopy of erythema dyschromicum perstans reveals brownish-gray with pink hue in background with bluish-gray (red arrows) and brown (yellow arrows) pigment globules. Out of focus vessels are well appreciated (green arrows). (c) Dermoscopy of acanthosis nigricans demonstrates linear crista cutis (yellow arrows) and sulcus cutis (red arrows) with scattered black or dark brown dots and globules (black arrows). Note the irregular size and shape of the pigment dots and globules. (d) Dermoscopy of chronic lesion of acanthosis nigricans demonstrates linear crista cutis (yellow arrows) and sulcus cutis (red arrows) and pigment globules (black arrows). Note the exophytic papillary structures are strikingly present (yellow box). Grayish-brown with pale white color is well appreciated in the background. (e) Dermoscopy of pigmented contact dermatitis shows regular arrangement of brown (yellow arrows) and bluish-gray (red arrows) pigment globules giving a reticular arrangement. Brownish-gray background and superimposition of brown globules over bluish-gray globules are well appreciated. White scales (black arrow) and perifollicular halo (green arrows) are present. (f) Dermoscopy of friction melanosis shows accentuated pseudopigment network with patchy distribution of brown (yellow arrows) and bluish-gray (red arrows) pigmented globules. Patulous follicular openings (yellow circles) are well appreciated. (g) Dermoscopy of seborrheic melanosis shows prominent pseudo network (blue circle) and dilated follicles with whitish-yellow plugs (black arrows). Note the erythematous background and white scales (yellow star)
