Which feature is NOT characteristic of a venous ulcer?

A feature that is characteristic of venous ulcers is a dry, even edge. Venous ulcers typically present with irregular borders and are often found on the medial malleolus, which is the bony prominence on the inner side of the ankle. In contrast, they usually have a wet and granulated appearance due to the presence of venous stasis and the accumulation of fluid.

The distinction of venous ulcers having irregular borders, occurring often in specific locations like the medial malleolus, and a wet or granulating surface is essential in recognizing them for appropriate treatment. Understanding these features helps differentiate venous ulcers from other types of ulcers, such as arterial ulcers, which may have more cleanly defined margins and a different appearance.
