AB  - BACKGROUND: Dermoscopy is a new method to diagnose and manage nail disorders. The 
      definite dermoscopic finding for onychomycosis, however, is still debatable. 
      OBJECTIVE: To identify the dermoscopic features that help differentiate between 
      onychomycosis (OM) and traumatic onychodystrophy (TOD). METHODS: A prospective 
      study of 65 patients with toenail abnormalities was conducted. The patients were 
      classified into OM and TOD groups using mycological tests (potassium hydroxide 
      test, fungal culture, and histological examination). OM was diagnosed from 
      positive results for all tests, while TOD was decided based on negative results 
      for all tests and evidence of foot trauma. Dermoscopic features were recorded and 
      compared between the two groups. RESULTS: Most patients of the 65 patients were 
      female (72.3%), and had a mean age of 67.9 years. Twenty-seven patients (41.5%) 
      were diagnosed with OM, all of which were distal and lateral subungual 
      onychomycosis. TOD, on the other hand, was determined in 38 patients. Dermoscopic 
      findings revealed that the yellow, clumping, sulphur-nugget-like debris in the 
      ruin appearance was significantly associated with onychomycosis (p = 0.002), 
      while ruin appearance without sulphur nugget was not statistically correlated 
      with onychomycosis (p = 0.068). CONCLUSION: The presence of sulphur nuggets in 
      the ruin appearance is a new and helpful dermoscopic feature for onychomycosis 
      diagnosis.
