Dermatologists Urge Clinicians to Leverage Dermoscopy for Accurate Benign Skin Lesion Identification

A new approach to dermoscopic analysis is empowering clinicians and physician associates (PAs) to confidently distinguish between benign and potentially malignant skin lesions,reducing needless anxiety and intervention. The insights come from a presentation delivered by orit Markowitz, MD, at the 2025 Summer Dermatology Conference of the Society for Pediatric Dermatology Association (SDPA) in Washington, DC.

Markowitz,an assistant professor of dermatology at the Icahn School of Medicine at Mount Sinai and Director of Pigmented Lesions and Skin Cancer at the Faculty Practice Mount Sinai Doctors’ Department of Dermatology,addressed common pitfalls in dermoscopic interpretation during her session,’Dermoscopy Track: Recognizing Benign Patterns in Dermoscopy: Tools for Clinical Confidence.’

Avoiding Misinterpretation of Common Benign Patterns

A key challenge, Markowitz explained, lies in the tendency for clinicians to become alarmed by clinically concerning features. “Clinicians,for example,might get very excited when they see something that clinically scares them,” she stated.She cited seborrheic keratosis as a frequent source of misdiagnosis. These lesions often exhibit tindling – a blue discoloration – and can even meet the criteria of the ABCDEs (Asymmetry,Border irregularity,Color variation,Diameter,Evolving) used to assess melanoma risk.

Though, a dermoscopic examination frequently enough reveals a entirely different picture. “Then you look dermoscopically, and you start worrying. but this is a benign lesion,” Markowitz clarified. She emphasized the importance of utilizing established categorization patterns to avoid overdiagnosis.Even seemingly aggressive-looking, elevated lesions can be benign if they demonstrate complete symmetry under dermoscopic evaluation. “That’s not an aggressive tumor, that’s not a nodular melanoma,” she asserted.

Key Takeaway: Symmetry matters

Even if a lesion appears concerning clinically, complete symmetry under dermoscopic evaluation is a strong indicator of a benign condition.

The ‘Color Wheel’ Approach to Dermoscopic Analysis

Markowitz’s ‘color wheel’ approach,a central theme of her conference presentation,encourages clinicians and PAs to pause and carefully consider the entirety of the dermatoscopic image. This method allows for a more objective assessment, moving beyond initial clinical impressions.

Explore the Color Wheel

The ‘color wheel’ approach emphasizes a holistic view of the dermatoscopic image, moving beyond initial alarming features to a more objective assessment.

When asked about practical advice for improving pattern recognition, Markowitz advocated for a return to foundational learning. “I like my textbook approach, and I’m told that it’s very popular among trainees, globally, which is nice,” she said. However, she also acknowledged the wealth of readily available online resources.

Building a Personalized Dermoscopic Image Library

Markowitz stressed the value of building a personal image library. “Way back when…when I started utilizing dermoscopy in my early practice, I always went back and looked at the images. whenever I would get a pathology result, especially one that I didn’t anticipate and even now today, I’m still going back and asking, ‘What did that look like dermoscopically? What did that look like clinically?'” she shared.

Actionable Tip: Start Your Library Today

Begin documenting dermoscopic images alongside pathology results to build a valuable, personalized reference library for future diagnoses.

She recommended utilizing tools like Dermoscopedia as a starting point, but ultimately tailoring diagnostic approaches to individual experience. “You’ll see my way of diagnosing. You’ll see a variety of other ways. Pick the one that makes the most sense for you. it’s going to be tailored to what your own image library has taught you.”

Beyond the Basics: Advanced Dermoscopic Patterns and Clinical Decision-Making

Building upon Dr. Markowitz’s insights on the importance of dermoscopy for accurate skin lesion identification, it’s crucial to delve deeper into recognizing more complex patterns. This involves expanding beyond basic symmetry assessment and considering more subtle dermoscopic features. Mastering these nuances allows clinicians to make more informed decisions, further reducing needless interventions and improving patient care. The core of this advanced approach lies in recognizing atypical and subtle patterns.

Understanding the nuances of dermoscopic interpretation is critical for those involved in skin cancer detection.This enables more confident and precise assessments.

Expanding Your Dermoscopic pattern Recognition Skills

Dermoscopy offers the ability to identify patterns undetectable to the naked eye, but these patterns are frequently enough complex.Clinical experience, a thorough image library, and a commitment to lifelong learning are key. Let’s explore specific patterns and techniques to enhance your skills:

Vascular Patterns: Analyzing blood vessel architecture within a lesion can provide valuable clues. Irregular vessels, such as dotted or comma-shaped vessels, can indicate a higher likelihood of malignancy. In contrast, a regular and uniform vascular pattern often suggests a benign lesion.
Peripheral Patterns: The border of a lesion can reveal important details. Look for subtle clues, like the presence or absence of a peripheral rim, to help analyze the border of a lesion. The border’s characteristics provide critical clues concerning the lesion’s nature.
Pigment Network Analysis: The pigment network (or lack thereof) within a lesion is a critical feature. Fine, uniform networks are frequently enough indicative of benign lesions like nevi, while atypical or absent networks require further evaluation.

The Role of Digital Dermoscopy and Artificial Intelligence

Digital dermoscopy, coupled with artificial intelligence (AI), is transforming the field. these tools offer enhanced image analysis capabilities, providing clinicians with objective data and second opinions. AI can help identify subtle patterns that might be missed by the human eye, aiding in earlier and more accurate diagnoses. These advanced technologies are not meant to replace the clinician but to assist in refining the diagnostic capabilities and reduce interpretation errors.

How does AI improve dermoscopy? AI algorithms can analyze dermatoscope images, identifying features and patterns linked to melanoma and other skin cancers.

Practical Tips for Advanced Dermoscopy Practice

Here are several actionable recommendations for implementing these advanced concepts:

Attend Workshops and Courses: Hands-on training and expert guidance can refine dermoscopic skills. There are plenty of workshops and courses available.
Consult with Colleagues: Discuss unusual cases with peers.A collaborative approach can lead to new insights and improved accuracy.
Stay Updated on Research: The field of dermoscopy is constantly evolving. Staying current with the latest research and technological advances ensures the best patient care.

Myths vs. Facts

Let’s address some common misconceptions regarding dermoscopy:

Myth: Dermoscopy is only useful for melanoma detection.
Fact: Dermoscopy is very helpful in identifying benign skin lesions and distinguishing them from potentially hazardous ones, and it is therefore relevant for the early detection of all kinds of skin cancer.
Myth: Dermoscopy is a replacement for clinical judgment.
Fact: Dermoscopy enhances the clinician’s clinical judgment by providing additional information to formulate a diagnosis. It’s a tool, not a replacement for assessment.

Frequently Asked questions

Here are some answers for some commonly asked dermoscopy questions.

How often should I update my image library? Regularly add new cases, especially those with confirmed pathology results, to improve your personal reference library.

Can AI replace a dermatologist? No, AI assists, it does not replace the diagnostic expertise of a dermatologist.
