[en] The medical history of a leg ulcer is spangled with episodes contributing to its chronicity before leading to possible healing. The complexity of the involved biological factors is undisputable. In order to simplify the management of these lesions, some doctors and nurses summarize the evolution of a leg ulcer in 3 phases according to the colour of the wound bed: black, yellow and red. The latter stage is commonly considered as a favourable condition for skin healing. We criticize such a concept by showing the anatomo-functional heterogeneity of the red wound bed.
