Dermoscopic criteria and basal cell carcinoma

Basal cell carcinoma (BCC) is nowadays the most frequent skin cancer in the fair-skinned population. Clinical suspicion for BCC diagnosis can be easy in advance cases, but it sometimes sets a real challenge wherein dermoscopy has proven to be a useful tool. Dermoscopy is a non-invasive diagnostic technique that improves the clinical diagnosis of pigmented and non-pigmented BCC representing a link between macroscopic clinical dermatology and microscopic dermatopathology. The dermoscopy of basal cell carcinoma is currently very well-known, as well as the clinical and histopathological features of BCC subtypes. Recently some flowcharts and algorithms for the most common subtypes of BCC have been proposed. We review the latest literature on the topic to describe the most frequent dermoscopy patterns for each subtype.
