X-linked agammaglobulinemia,or Bruton's agammaglobulinemia,is an immunodeficiency disease characterized by a block in early B cell maturation and absence of serum Ig.As in other B cell deficiencies,morphology of lymphoid tissues is most remarkable for absent or reduced follicles and germinal centers (i.e. ,the B cell zones).In contrast,T cell deficiencies usually do not affect follicle size,but follicles will lack germinal centers and there may be reduced parafollicular cortical regions (i.e. ,the T cell zones).
