Figure 5: (a) Onychoscopy in distal and lateral subungual onychomycosis shows spikes (arrows) at the proximal portion of onycholytic area (Illuco, polarized, ×10). (b) Onychoscopy in distal and lateral subungual onychomycosis shows longitudinal striae (blue arrow) with white, yellow and brown colors (pink star). This is typically termed as “aurora borealis” pattern (Dermlite DL3N, polarized, ×10). (c) Onychoscopy in total dystrophic onychomycosis reveals thickened nail plate and exfoliation suggestive of “ruin appearance” (Dermlite DL3N, polarized, ×10). (d) Onychoscopy in superficial white onychomycosis shows white opaque and friable spots (black stars) with slight scaling (black arrows) on the nail plate. Note the purplish-red linear streaks (yellow arrows) in the nail bed (Illuco, polarized, ×10). (e) Onychoscopy of onychomycosis of nail bed shows subungual hyperkeratosis as yellowish-white structures (pink arrows) (Dermlite DL3N, polarized, ×10). (f) Onychoscopy of viral warts affecting the proximal nail fold shows multiple red dots (black arrows) surrounded by white halos (yellow arrows) (Dermlite DL3N, polarized, ×10)
