Figure 4: (a) Onychoscopy of lichen planus in nail plate shows multiple transverse splits (black arrows) suggestive of onychorrhexis. Note the splinter hemorrhages (yellow arrows) in the nail bed (Dermlite DL3N, polarized, ×10). (b) Onychoscopy of lichen planus in nail bed shows white linear splits (arrows) and loss of lunula (stars). Fragmentation of total nail plate is well appreciated (Dermlite DL3N, polarized, ×10). (c) Onychoscopy of lichen planus in the nail plate with pterygium shows reddish-brown area (black stars) extending longitudinally from proximal nail portion onto the nail plate. Note the white keratotic surface (yellow stars) in the distal edge of pterygium (Illuco, polarized, ×10). (d) Onychoscopy of lichen planus in the nail plate shows chromonychia (yellow star), linear ridges (green arrows) and thinning and rough nail plate (blue arrow) (Dermlite DL3N, polarized, ×10). (e) Onychoscopy of lichen planus in hyponychium shows white fibrotic streaks (stars) begin in the free edge and converge at the centre of nail plate (Illuco, polarized, ×10). (f) Onychoscopy of eczema shows lusterless surface (black stars), tiny pits (black arrows) and white scales (yellow arrow). Note the pigmentary and vascular changes in the proximal nail fold (yellow star) (Dermlite DL3N, polarized, ×10)
