Final answer:
Abnormally high lymphocyte counts are characteristic of viral infections and some types of cancer. Burkitt lymphoma is associated with the Epstein-Barr virus and has solid tumors consisting of aberrant B cells. Vacuoles can be seen in variant lymphocytes and as a reaction to viral infections, radiation, and chemotherapy.
Step-by-step explanation:
Abnormally high lymphocyte counts are characteristic of viral infections as well as some types of cancer. Abnormally low lymphocyte counts are characteristic of prolonged (chronic) illness or immunosuppression, including that caused by HIV infection and drug therapies that often involve steroids.
Frequently associated with Niemann-Pick disease, Tay-Sachs disease, Hurler's syndrome, and Burkitt's lymphoma. Vacuoles can also be seen in variant lymphocytes and as a reaction to viral infections, radiation, and chemotherapy.
In patients with malaria or HIV, Epstein-Barr virus can lead to a fast-growing malignant cancer known as Burkitt lymphoma. This condition is a form of non-Hodgkin lymphoma that produces solid tumors chiefly consisting of aberrant B cells.
