1 Tertiary lymphoid neogenesis is a component of pulmonary lymphoid hyperplasia in patients with common variable immunodeficiency  Paul J. Maglione, MD, PhD, Huaibin M. Ko, MD, Mary B. Beasley, MD, James A. Strauchen, MD, Charlotte Cunningham-Rundles, MD, PhD  Journal of Allergy and Clinical Immunology  Volume 133, Issue 2, Pages (February 2014) DOI: /j.jaci Copyright © 2013 American Academy of Allergy, Asthma & Immunology Terms and Conditions

2 Fig 1 The B-cell/T-cell ratio is variable in patients with CVID-associated PLH. A, Immunohistochemical staining of lungs for 2 representative patients demonstrating that the B-cell/T-cell ratio is variable among patients with CVID-associated PLH (original magnification ×40). B, Flow cytometric analysis of lungs from a representative patient with CVID-associated PLH.

3 Fig 2 Pulmonary lymphocytes are organized into B- and T-cell zones in patients with CVID-associated PLH. Hematoxylin-eosin and immunohistochemical staining for CD3 (T cells) and CD20 (B cells) is shown for 5 patients. Areas of B- and T-cell predominance are labeled as B and T, respectively. Magnification of images is ×40. Journal of Allergy and Clinical Immunology  , DOI: ( /j.jaci ) Copyright © 2013 American Academy of Allergy, Asthma & Immunology Terms and Conditions

4 Fig 3 Ectopic follicles and germinal centers with localized proliferation in patients with CVID-associated PLH. Magnification is ×100 in patient 1, ×40 in patient 4, and ×200 in patient 5.

5 Fig 4 CT scan of the chest of patient 1 before and 2 months after rituximab treatment. The CT scan demonstrated significant interval improvement after rituximab treatment, with resolution of ground-glass and solid opacities, as well as hilar and mediastinal adenopathy, with few persistent scattered nodules that were stable or smaller than those in the prior study.
