Answer

Answer

PCNSL is a densely cellular, aggressive non-Hodgkin B-cell lymphoma. Immunocompetent patients usually have a small, noncleaved cell or immunoblastic subtype. Perivascular clusters of lymphocytes and T-lymphocyte infiltrates are common in immunocompetent patients. T-lymphocyte infiltrates are not found in patients with AIDS.
