Introduction to the Series

Welcoming words from the Chair

Professor Aimilios Lallas is giving an introductory lecture on dermoscopy. He explains that the dermatoscope is like a dermatologist’s stethoscope because they are small, low-cost, and fast to use instruments that are carried everywhere. Lallas emphasizes that dermoscopy is important because it is beautiful and fascinating, and many dermatologists have become addicted to using it in their practice. He explains that dermoscopy is already a present reality and will be even more important in the future.
The presentation is about Trichoscopy, which is a technique used to evaluate hair and scalp structures with the help of a Trichoscope or Dermoscope. The speaker, Professor Lidia Rudnicka, will discuss four basic types of structures: hair shaft, follicular openings (dots), skin surface, and blood vessels. She will start by explaining normal hair structures and then go on to cover hair shaft abnormalities, such as exclamation mark hairs in Alopecia Areata and Trichotillomania. The speaker will also discuss hair miniaturization, which is a specific feature of Androgenic Alopecia, and contrast it with Telogen Effluvium. The final part of the presentation is for the “super experts” and will cover rare cases in Trichoscopy.
Professor John Paoli is giving a lecture on the dermoscopic features of basal cell carcinoma subtypes and how to recognize them. He highlights the common findings of branched vessels, short fine telangiectasias, shiny white blotches and strands, and pigmented structures. He explains that the brown-gray structures indicate superficial locations, while the gray-blue structures are deeper and more invasive subtypes. He shows real dermoscopic images to illustrate these structures.
