Summary
Retronychia, a condition where the nail embeds into the skin, causes inflammation and persistent paronychia. Simple nail avulsion effectively treats retronychia, preventing recurrence.
Area of Science:
- Dermatology
- Nail Biology
Background:
- Retronychia is characterized by incomplete nail shedding, leading to nail embedding in the proximal nail fold.
- This condition results in inflammation and persistent paronychia, often associated with disrupted nail growth.
Observation:
- Patients with retronychia present with symptoms of persistent paronychia and may exhibit other nail changes.
- Two cases of retronychia are presented, one associated with distal onycholysis and the other with subungual hematoma.
Findings:
- Simple nail avulsion was found to be a curative treatment for retronychia.
- Unlike other forms of ingrown nails, retronychia treated with avulsion demonstrated no tendency to recur.
Implications:
- Nail avulsion offers a definitive treatment for retronychia, resolving inflammation and paronychia.
- Understanding the unique presentation and treatment of retronychia is crucial for effective clinical management.
