Dermoscopy CME module
Onychoscopy
Presented by Ashfaq Marghoob, MD
Algorithm for nail pigmentation: first, determine if the band originates at the lunula. If not, favor subungual hemorrhage or onychomycosis; confirm via free-edge examination or short-interval follow-up. If yes, assess hyponychium/eponychium and free edge. Biopsy for flags—>50% involvement, Hutchinson sign, proximal-wider triangle, dystrophy—or disorganized, multicolored lines.
