Hi there I never have had psoriasis, but I did have a leukoplakia amend what they thought was lichen planus - my story is much the same as yours but my staging was two - with a spread to one lymph node. Mind you this had been going on for 10 yrs almost. Congrats on the three years - that's awesome!
