Figure 2: PET images and lymph node histology. PET scan images demonstrating uptake in a right supraclavicular lymph node and sub-carinal and hilar lymph nodes (panel A) are shown. Panel B displays an H&E stained section of a left jugular lymph node demonstrating partial effacement by a mixed population of small lymphocytes and histiocytes interspersed with scattered large atypical B-cells (200X).
