Figure 2: (a) Onychoscopy of longitudinal melanocytic nevus shows uniform dark brown band homogenous in color and width (black arrows). Note the continuation of pigment band under the transparent cuticle and proximal nail fold (yellow arrows). This is called as pseudo-Hutchinson's sign (Dermlite DL3N, polarized, ×10). (b) Onychoscopy of distal free edge of nail plate shows presence of pigmentation on the dorsal surface of plate suggesting the origin of nevus in proximal nail matrix (Dermlite DL3N, polarized, ×10). (c) Onychoscopy of subungual hematoma of recent injury shows purple or bluish-black areas (yellow star) with round proximal margins (red arrow) and filaments and streaks (yellow arrows) at distal end. Note the whitish glazed appearance (red star) typical of hematoma. Appreciate the brownish color (yellow star) of election voting ink which is superficial on the nail surface (Dermlite DL3N, polarized, ×10). (d) Onychoscopy of subungual hematoma of older trauma shows yellowish-brown area (Dermlite DL3N, polarized, ×10). (e) Onychoscopy of true leukonychia shows clusters of white globules in deep part of the nail plate (Dermlite DL3N, polarized, ×10). (f) Onychoscopy of pseudoleukonychia shows opaque white clods on surface of nail plate (Dermlite DL3N, polarized, ×10)
