title: Pernicious anemia in a patient with hypogammaglobulinemia.
abstract: A 19-year-old male with pernicious anemia and hypogammaglobulinemia (common variable immunodeficiency: CVID) is reported in comparison with classical pernicious anemia. This case was characterized by an earlier onset of anemia, the absence of autoantibodies to intrinsic factor or gastric parietal cells and involvement of the pyloric antrum as well as the gastric corpus. It is suggested that dysregulation of cellular immunity produces the autoimmune lesion in the gastric mucosa, including the pyloric antrum, in a patient with CVID, and that some of such cases develop pernicious anemia.
