Abstract:
Chronic lower leg ulcers (LLUs) are a very common and associated with a high subjective and economic burden. They can be caused by a variety of factors. We have observed a common clinical feature in patients suffering from LLUs, which ultimately proved to be basal cell carcinomas (BCCs). We have nicknamed this sign "the pink doughnut sign." The pink doughnut sign can aid in the early recognition of such BCCs, which is crucial to prevent unnecessary suffering, treatment costs, and poor local outcomes.
