Differential diagnosis of venous leg ulcer

Some conditions cause wounds that are similar in appearance to venous ulcers. It is therefore very important that these different conditions are not confused since the appropriate treatment for one disease may be contraindicated for another one.

The most common conditions responsible for chronic leg wounds are:

Chronic Venous Insufficiency (CVI).
Mixed insufficiency (with a venous component and an arterial component) (read more...)
predominantly arterial mixed ulcer

Arterial insufficiency (read more...)
ulcer of purely arterial origin

Microcirculatory disorders and diabetic microangiopathy
Necrotising angiodermatitis
Neuropathic origin
Pyoderma gangrenosum
pyoderma gangrenosum


Finally, it is important to watch out for chronic ulcers caused by malignant diseases, such as basocellular carcinoma or epidermoid carcinoma or very rare skin metastases observed in systemic cancers.
