Skin changes — look for hyperpigmentation (brown-red discolouration caused by haemosiderin deposition), venous eczema (itchy, red, scaly, and/or flaky skin which may have blisters and crusts on the surface), lipodermatosclerosis (painful, hardened, tight skin), and atrophie blanche (star-shaped, ivory-white, depressed, atrophic scars with surrounding pigmentation). See the CKS topic on Venous eczema and lipodermatosclerosis for more information.
