Dermoscopy: Learning from Easy and Difficult Cases

The presentation focused on the use of dermoscopy in diagnosing basal cell carcinoma (BCC) through the analysis of both easy and challenging cases. The speaker showcased multiple clinical examples, emphasizing distinguishing features observed through dermoscopy. For instance, the presence of bright red branched vessels and shiny white structures was indicative of BCC, while the absence of these features suggested alternative diagnoses like an intradermal nevus. The discussion underscored the role of clinical topography in subtyping BCCs, particularly differentiating between nodular, superficial, and infiltrative types based on the texture and surface of the lesions. Critical insights included recognizing that infiltrative BCCs could still appear raised and well demarcated, countering initial assumptions based on appearance alone. The speaker encouraged participants to become adept at correlating dermoscopic findings with clinical observations, particularly looking for vessels within ulcerations as a hallmark of aggressive BCCs. Overall, the session provided practical knowledge on using dermoscopy effectively for skin cancer diagnosis and highlighted continued learning through case analysis.
