Deep tissue defect of the skin of varying genesis which extends so deeply that there is no surface or deep epithelium left to re-epithelialise the defect. An ulcer may extend into the subcutis. Its healing always occurs with the formation of a scar.

An ulcer should be defined by size, by description of duration, depth, localisation (e.g. crural ulcer), surface (e.g. ulcerated), marginal condition and, if appropriate, aetiology (e.g. venous leg ulcer).

A distinction is made according to the duration of the tissue defect (acute/chronic), the localization (e.g. leg ulcer) and the underlying causes (arterial, venous, vasculitic, neoplastic, infectious, neuropathic).
