^aSeven patients did not fit the diagnosis pathway: 3 with Burkitt lymphoma are described in the text; 1 with diffuse large B-cell lymphoma presented with cervical lymphadenopathy, abdominal mass, massive ascites, and peritoneal fluid cytology evaluation that was suspicious for diffuse large B-cell lymphoma; 2 with Hodgkin lymphoma presented with abdominal masses—one with prolonged duration of massive lymphadenopathy and the other with a chest wall mass—and 1 with lymphoblastic lymphoma presented with bulging peripheral lymphadenopathy and severe pancytopenia, which may have represented a patient with acute lymphoblastic leukemia versus lymphoma.
