Onychauxis, localized hypertrophy of the nail plate, is characterized by thickened, hyperkeratotic, and discolored nails, often accompanied by subungual hyperkeratosis and loss of translucency [1]. Onychauxis is often caused by traumatic onychodystrophy, involving chronic nail malformations resulting from repetitive external injuries [2]. Clinically, onychauxis presents similarly to onychomycosis, leading to frequent misdiagnosis and inappropriate treatment with antifungal therapy [2]. Common complications of onychauxis include distal onycholysis, increased susceptibility to onychomycosis, and pain due to constant pressure on surrounding tissues [3].
