2. Figure 1
A, Chest radiograph showing mediastinal and bilateral hilar enlargement and diffuse linear and nodular opacities in both lung parenchyma. B, PET scan shows increased uptake of 18F-fluordeoxyglucose in the left shoulder and in the cervical, mediastinal, abdominal, and inguinal lymph nodes. C, Chest high-resolution CT scan reveals honeycombing (black arrowheads), nodules (white arrowheads), patchy ground-glass attenuation (white *), and traction bronchioloectasis (arrow). D, Diffuse and symmetric adenopathy (black *).

3. Figure 2
A, Lymph node showing expansion of interfollicular areas. The inset shows that atypia or multinucleation is not evident in the infiltrating plasma cells (hematoxylin and eosin [H&E] stain, original magnification ×20; inset, ×100). B, Thickening of alveolar septa is seen with dense lymphoplasmacytic infiltration and mild fibrosis (H&E stain, original magnification ×10). C, Part of a lung nodule (0.7 cm in greatest dimension) shows mild phlebitis in the center area (Verhoeff-Masson trichrome stain, original magnification ×2). D, Immunopositivity for IgG4 in the infiltrating plasma cells (Verhoeff-Masson trichrome stain, original magnification ×20).
