Figure 1. CT pulmonary angiogram had no evidence of pulmonary embolism (A), but disclosed multiple large mediastinal adenomegalies (B) and pleural effusion with atelectasis or consolidation in the adjacent area of the lungs (C).
Figure 3. (Upper) Photomicrograph of mediastinal lymph node stained with HE (original magnification 100 ×): note the reduced germinal center formation and loss of lymph node architecture by mononuclear cell proliferation into interfollicular spaces, as observed in the plasma cell variant of Castleman’s Disease. (Lower) Photomicrograph of mediastinal lymph node showing deposition of hyaline amorphous material and concentric rings of small lymphocytes around vessels, with onion-skin appearance, HE, 400 ×.
