Dermoscopic evaluation of melanonychia

Area of Science:

• Dermatology
• Oncology

Background:

• Melanonychia affects approximately 1% of the population and is frequently seen in clinical practice.
• While often benign, melanonychia can be an early sign of subungual melanoma.
• Distinguishing benign from malignant melanonychia can be challenging for clinicians using standard clinical evaluation.

Purpose of the Study:

• To highlight the diagnostic challenges in evaluating melanonychia.
• To emphasize the utility of dermoscopy in adult melanonychia assessment.
• To underscore the need for a different diagnostic approach for pediatric melanonychia.

Main Methods:

• Clinical evaluation and imaging of adult melanonychia.
• Dermoscopic examination utilizing an established algorithm.
• Comparative analysis of dermoscopic findings in adult and pediatric cases.

Main Results:

• Dermoscopy provides crucial information for diagnosing adult melanonychia.
• Pediatric melanonychia presents unique dermoscopic features.
• Features indicative of melanoma in adults are often associated with benign conditions in children.

Conclusions:

• Dermoscopy is a valuable tool for evaluating adult melanonychia.
• A distinct diagnostic strategy is necessary for pediatric melanonychia.
• Understanding age-specific dermoscopic patterns is key to accurate diagnosis and management.
