As specific autoimmune disorders now constitute established risk factors for malignant lymphomas, we describe this association. We review reported risk levels, risk determinants, lymphoma subtypes and biological mechanisms in autoimmunity/inflammation, emphasizing on recent findings. ⋯ Studies highlight associations with diffuse large B-cell lymphoma, apart from lymphoma development in target organs of inflammation. Future studies of high-risk patient subsets using detailed assessments of autoimmunity/inflammation and lymphoma may give important clues to lymphomagenesis.

Infectious aetiology of Hodgkin and non-Hodgkin lymphomas: a review of the epidemiological evidence.
Lymphomas constitute a heterogeneous group of malignant disorders with different clinical behaviours, pathological features and epidemiological characteristics. For some lymphoma subtypes, epidemiological evidence has long pointed to infectious aetiologies. ⋯ EBV, human herpesvirus 8), induce immunosuppression (human immunodeficiency virus), or cause chronic immune stimulation (hepatitis C virus, Helicobacter pylori), all of which may play a role in the development of various non-Hodgkin lymphoma subtypes. Here, we review the epidemiological evidence linking infections with malignant lymphoma.
