- Incompetence of deep perforating veins increases hydrostatic P in dermal capillaries. Pericapillary fibrin deposition impedes oxygen diffusion and leads to clinical changes.
- Leashes of venules and haemosideirin pigmentation around the ankles are early signs.
- Eczema develops, sometimes with fibrosis of the dermis and subcutaneous tissue (lipodermatosclerosis) and ulceration.
- Contact allergy to an applied medicament can complicate the picture.
Rx:
