Dermoscopy Decoded

In this episode of Cutaneous Miscellaneous, host Nicholas Brownstone, MD, is joined by dermatologist and dermatopathologist Michelle Tarbox, MD, to break down a crucial resident skill: dermoscopy. They kick things off with practical board review on the busy dermis and vacuolar interface patterns, covering how to build a differential, what features not to miss (hello, sneaky metastases), and how to work through normal-looking slides that may not be so normal after all. Then they dive into dermoscopy, discussing how to learn it, how to use it in clinic, and why it’s become the dermatologist’s equivalent of a stethoscope. Dr. Tarbox shares real clinical cases—including melanoma masqueraders, foreign body imposters, and heart-shaped seborrheic keratoses—with image-by-image insights on what to look for and why. Whether you're prepping for boards or aiming to sharpen your day-to-day diagnostic skills, this episode is packed with high-yield pearls and a few great analogies, too.
