Clinical signs of B12 deficiency may be subtle and missed, particularly in patients with known autoimmune disease. The first thing to consider and rule out is solid tumors as they can cause elevated B-12 levels. Clinically, it can be paradoxically accompanied by signs of deficiency, reflecting a functional deficiency linked to qualitative abnormalities, which are related to defects in tissue uptake and action of vitamin B12. We evaluated the incidence of solid cancers following B12 measurement in patients with persistent elevated B12, compared to patients without elevated B12 and to patients with non-persistent elevated B12.
