Dermoscopy, Revisited: Seeing With Intention
As the 2026 Winter Clinical Dermatology Conference kicks off in Hawaii, this editorial launches our Continuity Experience with a return to fundamentals, reframing dermoscopy not as pattern memorization, but as disciplined clinical thinking under the scope.
By Dermsquared Editorial Team
Dermoscopy is familiar to us all. It’s woven into the rhythm of clinic, pulled out between rooms almost reflexively, and serves as an important tool in our clinical armamentarium. And yet, even as dermoscopy becomes more routine, its impact still hinges on how we use it.
At this year’s Winter Clinical - Hawaii, Michelle Tarbox, MD, leads a dermoscopy workshop designed not as a basic refresher, but as a recalibration. It’s a return to fundamentals in a clarifying way, because dermoscopy isn’t about memorizing patterns. It’s about thinking clearly through the lens of the dermatoscope.
This editorial marks the first chapter of our Winter Clinical Continuity Experience. Whether you’re in the room in Hawaii or following along from afar, consider it a way to align your thinking before the evaluating dermoscopic images.
Dermoscopy Is an Extension of the Exam, Not a Shortcut
Dermoscopy deepens the physical exam. It increases diagnostic confidence, strengthens patient trust, and can support earlier melanoma detection while possibly reducing unnecessary biopsies. But none of that is automatic.
Dermoscopy does not replace clinical judgment nor does it replace histopathology. What it does offer is access to a noninvasive view of subsurface structures that are otherwise invisible to the naked eye. The value comes from how well those visual clues are interpreted in context—patient age, lesion history, anatomic site, and change over time.
That distinction matters, especially as dermoscopy remains a critical tool in the exam room.
Seeing More Means Switching Modes
One of the most common dermoscopy pitfalls is also one of the simplest: relying on only one viewing mode.
Polarized dermoscopy excels at revealing deeper structures like vascular patterns, collagen alterations, shiny white (chrysalis) structures, and scar-like areas. Nonpolarized dermoscopy, by contrast, preserves true color and highlights surface features: milia-like cysts, comedo-like openings, blue-white veil, and regression structures.
Each mode tells a different part of the story. Many diagnostically important clues only become apparent when you deliberately toggle between polarized and non-polarized light.
From Pattern Recognition to Structured Thinking
Experienced clinicians often feel when a lesion is wrong before they can articulate why. Dermoscopy gives language to that instinct, but only if it’s approached systematically.
A structured dermoscopic exam starts globally, then moves locally:
- Global pattern: Is the lesion symmetric or asymmetric? Is there order or chaos?
- Local features: What structures appear when you zoom in? Where are they distributed? Are they uniform or irregular?
This framework helps distinguish benign complexity from malignant heterogeneity. Not every multicomponent pattern is dangerous, and not every irregularity demands a biopsy, but asymmetry paired with architectural chaos should always make you take a closer look.
Pigment, Vessels, and the Clues That Matter Most
Some dermoscopic findings are subtle but high-yield.
Shiny white streaks (chrysalis structures), visible only with polarized light, often reflect dermal fibrosis and can be seen in invasive melanomas and basal cell carcinomas. Polymorphous vascular patterns raise concern in amelanotic and hypomelanotic melanomas, where pigment alone may not guide you. Regression structures, white scar-like areas and blue-gray peppering, signal immune-mediated tumor destruction and deserve particular attention.
Distribution matters as much as presence. Peripheral globules in a young patient may be reassuring; the same finding in an adult should prompt caution. Balance, symmetry, and context remain important principles of dermoscopy.
Dermoscopy Is a Skill You Actively Maintain
Like any procedural or cognitive skill, dermoscopy benefits from deliberate practice. That includes attention to technique (contact vs non contact, infection control), equipment optimization, and a willingness to think critically when something doesn’t fit neatly into a known category.
The goal is not diagnostic perfection; it’s better triage. Knowing when to biopsy, when to monitor, and when to look again, differently.
What Comes Next
This workshop is only the beginning of the conversation. Over the coming weeks, the Winter Clinical 2026 Continuity Experience will expand into short-form videos, case-based discussions, and practical takeaways designed to live well beyond the conference.
For now, the invitation is simple: approach dermoscopy with intention. Revisit your assumptions. Switch modes. Think globally before zooming in. And remember that seeing more clearly often starts with slowing down just enough to ask better questions.
Whether you’re holding a dermatoscope in Hawaii this weekend or back in your own clinic on Monday morning, the work is the same: seeing what’s there and understanding what it means.
