ult D Abstract One quarter of all cancers are linked to infectious diseases. The link between viral infection and cancer has been widely studied, but few reports have focused on the carcinogenic role of bacterial infection. Nonetheless, Helicobacter pylori, Chlamydia psittaci, Coxiella burnetii, Borrelia burgdorferi and Campylobacter jejuni are bacteria that can be associated with non-Hodgkin's lymphoma (NHL), the most common haematologic malignancy. Here, we review the evidence in favour of a link between these bacterial infections and NHL. Sero-epidemiological observation makes it possible to identify a link bet...

Ferreri In the last decades some bacteria have been associated with a various extent with marginal zone (extra nodal, nodal and splenic types) lymphomas are frequently associated with chronic infections, with important clinical, molecular, biological, and therapeutic implications. The well-known correlation between Helicobacter pylori and gastric MALT-lymphoma, the recently reported links between Chlamydia psittaci and ocular adnexal MALT-lymphoma and Borrelia burgdorfe...

We read with great interest the review of Borie et al. [1] on pulmonary lymphoma of the mucosa-associated lymphoid tissue (MALT). We agree with the hypothesis that chronic antigen stimulation of microbial origin may lead to the development of pulmonary MALT lymphoma. Indeed, MALT lymphoma has been associated with various chronic infections in extrapulmonary localisations. This link has previously been demonstrated between Helicobacter pylori infection and gastric MALT lymphoma, and suggested with Campylobacter jejuni, Chlamydia psittaci and Borrelia burgdorferi with small intestine lymphoma, ocular annexa lymphoma and cuta...

Abstract: CD4+ small/medium pleomorphic T-cell lymphoma is a relatively rare subtype of cutaneous lymphoproliferative disorder with an indolent clinical behavior. The place of this condition among lymphomas is debatable. The authors describe a rare case of the direct association of CD4 small/medium pleomorphic T-cell lymphoma–like solitary nodule with Borrelia burgdorferi infection in a 5-year-old boy, discuss the reactive nature of this condition, and emphasize the importance of clinicopathological correlation.

Last week, I mentioned the case of Dr. Neil Spector, whose long-undiagnosed Lyme Disease resulted in irreversible heart failure and ultimately, a heart transplant. Dr. Spector, author of Gone in a Heartbeat: A Physician's Search for True Healing, is the Sandra Coates Associate Professor of Medicine and Associate Professor of Pharmacology and Cancer Biology at Duke University School of Medicine. As the Director of Developmental Therapeutics at the Duke Cancer Institute, he's a leader in applying translational research to the clinical development of molecularly targeted personalized cancer therapies. Here, Dr. Spector share...

Marginal zone lymphomas have been associated with several infectious agents covering both viral and bacterial pathogens and in some cases a clear aetiological role has been established. Pathogenetic mechanisms are currently not completely understood, however the role of chronic stimulation of the host immune response with persistent lymphocyte activation represents the most convincing explanation for lymphoproliferation. Gastric MALT lymphoma is strictly associated with Helicobacter pylori infection and various eradicating protocols, developed due to increasing antibiotic resistance, represent the first line therapy. The r...

We report an unusual constellation in a patient with synchronously diagnosed B-CLL and Borrelia infection of skin presenting with a dense dermal T-cell–rich infiltrate masking specific leukemic infiltrates of neoplastic B cells in the context of B-CLL harboring t(14;18)(q32;q21). Specific cutaneous involvement by B-CLL was confirmed by the detection of t(14;18)(q32;q21) (BCL2–IGH) using FISH in neoplastic B cells within the skin infiltrates. Borrelia burgdorferi (sensu lato) DNA detected by nested polymerase chain reaction in the skin biopsy and serological findings proved Borrelia infection. Complete resolutio...

Abstract Marginal zone lymphomas (MZL) represent around 8 % of all non-Hodgkin lymphomas. During the last decades a number of studies have addressed the mechanisms underlying the disease development. Extranodal MZL lymphoma usually arises in mucosal sites where lymphocytes are not normally present from a background of either autoimmune processes, such as Hashimoto thyroiditis or Sjögren syndrome or chronic infectious conditions. In the context of a persistent antigenic stimulation, successive genetic abnormalities can progressively hit a B-cell clone among the reactive B-cells of the chronic inflammatory tiss...
