Psoriasis does not normally leave purple patches
it usually fades with hypopigmentation
are these purple patches located in the exact location of the psoriatic plaques?
some yes....some where plaques used to be
originally they thought it was stasis....but I've had my veins checked out and although there is minimal reflux, the vein surgeon does not believe the spots are consistent with iron staining from stasis
Is it possible for you to take a few pictures of these purple spots?
sure...how would I get them to you?
are you working on a windows pc or a mac?
in the text box do you see a tree icon in the upper bar?
ok...just a sec
Got it. Gimme a minute to type out the answer
Your history as well as clinical picture are consistent with a diagnosis of pigmented purpuric dermatosis (PPD). PPD is a harmless condition caused due to microvascular leakage of blood into the skin. This occurs either spontaneously or on prolonged standing or walking. The basic cause is due to poor capillary support as the anchoring proteins which do this job in the skin decrease with age + mild capillaritis. No treatment is required. The condition is essentially harmless and usually keeps recurring and fading. Ultimately there may be some hyperpigmentation in the involved area. For patients keen on treatment here is what I recommend: 1. Tab Calcium Dobesilate 500 mg twice a day for 6 weeks. 2. Tab Vitamin C 500 mg once a day. 3. Fluticasone propionate cream twice a day for 7-14 days. 4. Avoid prolonged standing or walking. Leg elevation during rest. All these are prescription drugs however barring vitamin C.
what will this treatment accomplish?
and so you don't believe this has anything to do with psoriasis
The spots, especially the active purple ones fade. However they recur on stopping treatment, that is why I encourage my patients to leave them alone if they aren't too bothered by the cosmetic blemish
No this has nothing to do with psoriasis
