Definition / general

3% of GI lymphomas arise in rectum or anus in general population vs. 26% in AIDS patients (Am J Surg Pathol 1997;21:997)
AIDS lymphomas: usually high grade, EBV+
Non AIDS lymphomas: EBV-, less often high grade
High incidence of AIDS lymphomas may be due to prior local trauma or chronic infections
