I have dark, discoloured skin on ankle caused by dvt and venous ulcers. what treatments are available to get rid of the discolouration?

Time and patience: Unfortunately there is not a good treatment to address the discoloration that occurs from stasis changes and hemosiderin staining the skin surface. Try keeping your legs elevated while sitting, protect the skin from the sun, wear compression hose and reduce the sodium in the diet.

None: Not anything easy or common. The hemosiderin staining is persistent. Avoid more by elevation, stockings and avoid infection.

A few possibilities : I agree with dr wright, the treatment for the discoloration/ hyperpigmentation is focused on prevention of additional discoloration. The mainstay to of prevention is properly fitted compression stockings. However, sometimes there can smaller superficial refluxing veins that can be adding to the dark discoloration so it is best to get checked for this to be sure there is nothing more to be done.

None: The discoloration is due to the iron in the hemoglobin molecule that leaked into the skin and broke down causing the staining.

Zinc oxide: Sometimes is helpful. Amerigel makes a lotion and it helps reduce the hyper pigmentation if used twice daily.

Sorry: But most likely color will remain the same.

Hard to do: The discoloration is a deposit of iron oxide under the skin. It often lightens to some degree with proper treatment of the underlying venous disease but it is difficult to completely get rid of it.
