ABSTRACT
In distal subungual onychomycosis, dermoscopy shows that the onycholytic area has a jagged proximal edge with

• Distal subungual onychomycosis • Ragged proximal margin • White-yellow streaks and patches • Dermoscopy establishes proximal progression
• White supercial onychomycosis: Pseudoleukonychia
• Proximal subungual onychomycosis: Proximal true leukonychia
