Since the diagnosis of the underlying cause can be misleading, we investigated whether dermoscopy (onychoscopy) pre\u2010 and post\u2010clipping of the onycholytic nail plate can provide reproducible patterns to distinguish these causes without the need for a biopsy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and Methods<\/jats:title>\n                    <jats:p>In a multicenter retrospective image\u2010based study, 60 onycholytic fingernails were examined (20 patients per diagnosis: psoriasis, onychomycosis, trauma). Onychoscopy of the intact plate was followed by clipping of the detached nail plate and dermoscopic assessment of the exposed nail bed under both dry and wet conditions. Color, amount, thickness, adherence, mobility (\u201cwet test\u201d), and distribution of subungual scales were recorded. Multinomial logistic regression assessed independent associations between dermoscopic features and diagnostic categories.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      After clipping, dermoscopy revealed distinct nail\u2010bed patterns.
