Dermatology
Medical Case Reports

Background:

Ectopic nail is defined as nail malformation outside the standard nail unit.
Trauma is a potential cause of nail deformities and ectopic nail formation.

Observation:

A 12-year-old boy presented with a dystrophic thumb nail after an injury.
The ectopic nail was located beneath the original nail plate.
A longitudinal bridge formation connected the ectopic nail to the original nail plate, with parallel growth observed.

Findings:

Clinical presentation was consistent with a subungual posttraumatic ectopic nail.
The unique anatomical connection and growth pattern were key diagnostic features.

Implications:

This case highlights the importance of considering ectopic nail formation after trauma.
Understanding the specific presentation aids in accurate diagnosis and management of nail unit injuries.
