Retronychia: A Literature Review

Area of Science:

• Dermatology
• Nail Pathologies

Background:

• Retronychia is an underreported nail pathology.
• It frequently mimics other common nail disorders like ingrown toenails, fungal infections, and paronychia.
• Recent case studies highlight an increased focus on this condition.

Purpose of the Study:

• To review and analyze existing literature on retronychia.
• To identify commonalities in causes, patient demographics, clinical presentation, and treatment strategies.
• To emphasize the importance of recognizing retronychia for timely diagnosis.

Main Methods:

• Comprehensive literature search using PubMed and other medical databases.
• Inclusion of relevant reviews, case studies, and retrospective articles.
• Analysis of cited references for additional pertinent publications.

Main Results:

• Retronychia shares clinical similarities with onychocryptosis, onychomycosis, and paronychia.
• The condition appears to be more prevalent than historically documented.
• Common factors across reported cases were compiled and analyzed.

Conclusions:

• Retronychia may be underdiagnosed due to its resemblance to other nail conditions.
• Enhanced medical professional education is crucial for early and accurate diagnosis of retronychia.
• Further research and awareness can improve patient outcomes for this nail pathology.
