Abstract
Introduction: Chronic retronychia cases oftentimes look similar to congenital great toenail malalignment. It is quite possible that, on the toenails, both are related as both clinically portray changes in nail growth in a setting of ongoing microtrauma.
Case presentation: A 2-year-old girl presented with a left great toenail change compatible with chronic retronychia. The likely culprit was a lateral deviation of the distal phalanx. Only conservative measures were recommended but an onset of retronychia-related complications was already appreciable.
Conclusion: This case illustrates the relationship between retronychia and what could be veritably called acquired great toenail malalignment.
