In this session, Associate Professor Amanda Oakley will discuss a logical system to approach acral and nail unit lesions in a case-based way. She will outline an approach for the follow-up of new pigmented lesions on acral skin as well as her tips on differentiating between furrows and ridges. She will discuss ways to exclude pigmented and non-pigmented diagnoses of the nail as well as a way to approach white or red nail stripes (longitudinal leuconychia and erythronychia).
