Nail clippings target the nail plate instead of subungual hyperkeratosis. Chang et al, in 2007, described a modified approach to the histological examination of onychomycosis based on examination of subungual hyperkeratosis Subungual hyperkeratosis is scaling under the nail due to excessive proliferation of keratinocytes in the nail bed and hyponychium. Transverse lines and ridges are due to intermittent inflammation, causing growth arrest followed by hyperproliferation in the proximal nail matrix. The lines and ridges move out distally as the nail grows
