Concurrent beau lines, onychomadesis, and retronychia following scurvy.
Overview
abstract
Beau lines, onychomadesis, and retronychia are nail conditions with their own characteristic clinical findings. It has been hypothesized that these 3 disorders may share a common pathophysiologic mechanism of slowing and/or halting nail plate production at the nail matrix. We report the case of a 41-year-old woman who presented with concurrent Beau lines, onychomadesis, and retronychia 6 months following a diagnosis of scurvy. Simultaneous presentation of these 3 nail conditions is not commonly reported, and our case supports a shared pathophysiologic basis.
