  Fig. 1 (A) Dermoscopy of the nail plate showing homogeneous white bands with splinter hemorrhages (inset: clinical image). (B) Nail edge dermoscopy revealing a 2-mm subungual keratotic mass. (C) Dermoscopy of the nail plate showing V-shaped longitudinal leukonychia extending from the distal lunula border to the free edge of the nail plate. Splinter hemorrhages present with distal onycholytic change (inset: clinical image). (D) Nail edge dermoscopy disclosing a 4-mm hyperkeratotic mass lifting the nail plate at the hyponychium.
