“…Comparing to previous studies, 1,[15][16][17][18][19] our findings were concordant, demonstrating two patterns systematically associated with OM: IMa and DP patterns. 1,[15][16][17][18] Their presence increased the likelihood for OM diagnosis, by about 43-fold and 33-fold, respectively ( Table 5). Although the specificity of both patterns for OM diagnosis was high (>96%), we did not find a 100% specificity as previously reported, 1,16 perhaps because we included a larger sample and we did not restrict our inclusion criteria to a specific subtype of OM (distal subungual onychomycosis).…”

“…The IMa ('jagged edged with spikes') pattern results from distal-to-proximal invasion of dermatophytes. 1,17,18 It is associated with a clearly defined matte discoloration obtained directly from the colour of invading fungal colonies and, indirectly, from inflammatory scaling and subungual debris accumulation. 1,15 In our study, this was the most frequent presentation of OM (53.6%, n = 59).…”

“…Diffuse subungual hyperkeratosis is typically seen in psoriasis and distal subungual onychomycosis. A large study described a new pattern of subungual hyperkeratosis discovered in distal subungual onychomycosis, i.e., a “ruin appearance” of subungual hyperkeratosis on dermoscopy that corresponds to a fungal presence [43]. …”

“…Nail plate dermoscopy reveals a jagged edge appearance of the proximal margin of the onycholytic area with spikes directed to the proximal nail fold, and overall irregular pigmentation in longitudinal striae of different colors, giving an appearance similar to the aurora borealis [17] . Dermoscopy, of the frontal margin of the affected nail plate shows a 'ruin appearance' of the subungual hyperkeratosis [18] .…”
