I have been bruising easily, and although the blood tests were all fine (no leukemia), they sent me for a CT scan to make sure that I did not have lymphoma. It appeared that I have a thickening of the kidneys. Should I be concerned? I m 43 year old male and have been experiencing other symptoms - osteoporosis, inverse psoriasis, fatigue, and purpuric lesions in flares (possible vasculitis - the test was inconclusive, but everything else was ruled out). All of these are indicative of lupus, but all of the autoimmune tests have come back negative. No one seems to have any answers. Do you?
