Figure 3: (a) Onychoscopy of nail psoriasis in nail plate shows trachyonychia with multiple keratotic white scales (stars). Note the dark red filaments and streaks (arrows) suggestive of splinter hemorrhages (Dermlite DL3N, polarized, ×10). (b) Onychoscopy of nail psoriasis in nail bed shows onycholysis (yellow arrows), irregular pits (black arrows) and reddish band (black stars) in the proximal portion of onycholytic area (Illuco, polarized, ×10). (c) Onychoscopy of nail psoriasis in nail bed shows dull red and ill defined structures (arrows) in the nail bed indicative of salmon spots. Variation in the shape and size of spots is well appreciated (Illuco, polarized, ×10). (d) Onychoscopy of nail psoriasis in free edge of nail plate shows yellowish-white area due to the accumulation of excessive keratin below the nail plate (Illuco, polarized, ×10). (e) Onychoscopy of nail psoriasis in hyponychium shows regularly arranged red dots on pinkish background (Illuco, polarized, ×10)
