Hi there Zeno. Being a Dermatologist this seems up my street. However, from your description, i seem to concur with the other dermatologists opinion in that it does appear to be Schamberg s disease . The pigmentation arises largely due to hemosiderin deposits & increases over a period of time. That is the underlying pathology but the pathogenesis itself appears unclear hence the remedies too are similar. Both Vit C & Vit K are powerful antoxidants & recommended for this virtue in your case. I presume you wear the medical socks on account of varicosities? Please do upload some clear photographs of both your lower limbs on this portal for a more holistic advice or consult with us using the premier package. They are right..harmless it most certainly is but unsightly especially for a woman. I did have a male doctor as a patient this morning with a similar issue. I always recommend sleeping with the foot-end of the bed raised & try to sit with your feet up & avoid standing for long periods..all general measures for improving the venous drainage of the area & limiting the damage. Use of a topical skin lightening cream may be useful & some of us dermatologists push for laser treatments but have not found them to be of much use..perhaps lighten the skin to an extent. Cheers & Wish you Good Health & Good Skin! Dr Praveen Rodrigues MD Dermatologist, Cosmetologist, Venereologist Vikram Hospital, Bangalore, India
