Inguinal lymph node excisional biopsy showed a composite lymphoma comprised of clonally distinct EBV-positive cHL, nodular sclerosis type (occupying 40–50% of lymph node space), EBV-positive primary nodal TNKL (50–60%), and classic (grade 1-2) FL (1-2%) (Figure 1). The gene discussed is TNKS2; the disease is classic Hodgkin lymphoma.
