Figure 1: (a) Chest radiograph showing a right upper zone opacity. (b) Computerized tomography axial chest showing a soft tissue density lesion in the right upper lobe with central hypodensity and surrounding irregular borders; (c) lesion shows predominant peripheral contrast enhancement; (d) lung window showing the opacity and surrounding emphysematous changes; (e) Microscopy of the lesion (×40, high power). Arrow shows the lymphoid follicle with hyperplasia and concentric arrangement of lymphocytes. Interfollicular area shows plasma cell infiltration
