Nails in systemic disease

摘要

A change in colour, size, shape or texture of finger- and toenails can be an indicator of underlying systemic disease. An appreciation of these nail signs, and an ability to interpret them when found, can help guide diagnosis and management of a general medical patient. This article discusses some common, and some more rare, nail changes associated with systemic disease.? Royal College of Physicians 2021. All rights reserved.
