A 57-year-old man presented with left neck swelling for three weeks. He was treated with antibiotics to no avail and was admitted for a lymph node biopsy. Physical examination showed bilateral nontender lymphadenopathy over the cervical, axillary, and inguinal regions. CT scan also revealed diffuse adenopathy throughout the neck, chest, and abdomen. A left cervical lymph node biopsy is depicted in Figs. 68.1, 68.2, and 68.3.
