Incidence varies depending on the institution, patient population, allograph types, and immunosuppression regimes.

Etiology/Histopathology

Clinical settings causing immune dysfunctions, such as viral Epstein-Barr virus (EBV) infection, human viral immunodeficiency, autoimmune disease, and posttransplantation, can cause clonal B- and T-cell lymphoid proliferations, effacing and altering the normal histology architecture and causing symptoms and mass lesions.
