Management of Dysplastic Nevi and other Pigmented Lesions
Description
The presentation by Sufi Chen focuses on the clinical management of dysplastic nevi and other pigmented lesions, emphasizing the importance of understanding terminology and proper biopsy techniques. Chen highlights the controversy surrounding the classification of dysplastic nevi as potential precursors to melanoma, noting the variability in pathology grading. A key part of the discussion includes evidence-based guidelines for managing cases of dysplastic nevi, underscoring the need for excisional biopsy with appropriate margins. Chen reviews findings from studies indicating that moderately dysplastic nevi with positive margins can be monitored, as they may serve as biomarkers for lifetime melanoma risk. The necessity for standardized data elements in electronic medical records for dysplastic nevi management is also stressed to facilitate better research and clinical practice. Through case scenarios, Chen engages the audience in decision-making processes regarding follow-ups and re-excisions based on histological findings, providing practical insights on how to handle various outcomes from biopsies and the role of patient follow-up in skin health.
View moreConclusions
- Dysplastic nevi may not always be precursors to melanoma, challenging traditional notions of progression.
- Optimal management of dysplastic nevi includes excisional biopsy with clear margins, followed by monitoring based on histologic findings.
- Mildly and moderately dysplastic nevi with clear margins after excision do not require reexcision.
- Moderately dysplastic nevi with positive margins but no residual pigmentation can be safely observed, but patients should be monitored for melanoma risk.
- Patients with multiple dysplastic nevi have a higher lifetime risk for developing melanoma elsewhere on the body, necessitating regular skin exams.
- There is a notable lack of standardized documentation practices for dysplastic nevus management, impacting data collection and patient outcomes.
- Standardizing data elements for clinical practices related to dysplastic nevi is crucial for enhancing future research and patient care.
