Hi. I am 98% of the way to a indolent systemic mastocytosis diagnosis. Apparently I also have psoriasis. I am very dubious about the psoriasis diagnosis because it appeared shortly after I started having the ism flares and the plaques go darker red and itch more when the flares happen. The psoriasis was diagnosed by a dermatologist who knew I was being investigated for ism, but he didn't do a skin biopsy. Does anyone else here have both conditions or mastocytosis lesions that look like psoriasis?
