PTLD represent major post-transplant complications. The major etiologic factor is EBV. Association with cold agglutinin disease has not been described so far. We report a three-yr-old girl who developed oligoclonal EBV-negative plasmacytic hyperplasia as well as Coombs test-positive anemia one yr after multivisceral organ transplantation, performed after subtotal bowel resection for colointestinal aganglionosis and
liver cirrhosis
resulting from long-term parenteral nutrition. The patient was treated for plasmacytic hyperplasia with cyclophosphamide and prednisolone and achieved clinical remission. One yr later PTLD progressed possibly driven by EBV to
DLBCL
. The migration patterns of the amplified Ig heavy chain genes demonstrated a probable clonal relationship of the
DLBCL
to a clone almost present in the plasmacytic hyperplasia. This progression was accompanied by a rapid rise of cold agglutinin titers with symptoms of severe cold agglutinin disease, leading to right femoral and extern iliac vein thromboses requiring partial leg amputation. After four cycles of rituximab, cyclophosphamide, and prednisolone, the patient achieved complete PTLD remission and the cold agglutinins disappeared. Summarizing, PTLD may be accompanied by cold agglutinin disease, and both may be successfully treated by immuno-chemotherapy. The appearance of cold agglutinins in transplant patients may indicate PTLD development.

A significant association between hepatitis C virus (HCV) infection and B-cell lymphoma has been reported by epidemiological studies, most of them describing a strong relationship between indolent lymphomas and HCV. Furthermore, the curative potential of antiviral therapy on HCV related indolent lymphomas supports a specific role for the virus in lymphomagenesis. These observations are reinforced by numerous laboratory experiments that led to several hypothetical models of B-cell transformation by HCV.
Diffuse large B-cell lymphoma
(
DLBCL
), the most common lymphoma subtype in the western countries, has been associated to HCV infection despite its aggressive nature. This association seems particularly prominent in some geographical areas. Clinical presentation of HCV-associated
DLBCL
has consistently been reported to differ from the HCV-negative counterpart. Nevertheless, histopathology, tolerance to standard-of-care chemo-immunotherapy (R-CHOP or CHOP-like regimens) and final outcome of HCV-positive
DLBCL
patients is still matter of debate. Addition of rituximab has been described to enhance viral replication but the probability of severe hepatic complications remains low, with some exceptions (i.e., hepatitis B virus or immune immunodeficiency virus co-infected patients, presence of grade > 2 transaminases elevation,
cirrhosis
or hepatocarcinoma). HCV viral load in this setting is not necessarily directly associated with liver damage. Overall, treatment of HCV associated
DLBCL
should be performed in an interdisciplinary approach with hepatologists and hematologists with close monitoring of liver function. Available reports reveal that the final outcome of HCV-positive
DLBCL
that receive standard immunochemotherapy is not inferior to their HCV-negative counterpart. This review summarizes data on epidemiology, pathogenesis and therapeutic approach on HCV-associated
DLBCL
. Several issues that are matter of debate like clinical management of patients with transaminase elevation, criteria for discontinuing or starting immuno-chemotherapy, as well as the exact role of monoclonal antibodies will be analyzed.

Acute liver failure is a rare presentation of hematologic malignancy. Acute on chronic liver failure (ACLF) is a newly recognized clinical entity that describes acute hepatic decompensation in persons with preexisting liver disease.
Diffuse large B-cell lymphoma
(
DLBCL
) is an aggressive non-Hodgkin's lymphoma (NHL) with increasing incidence in older males, females and blacks. However, it has not yet been reported, to present with acute liver failure in patients with preexisting chronic liver disease due to human immunodeficiency virus (HIV)/hepatitis C virus (HCV) co-infection. We describe a case of ACLF as the presenting manifestation of
DLBCL
in an elderly black man with HIV/HCV co-infection and prior Hodgkin's disease in remission for three years. The rapidly fatal outcome of this disease is highlighted as is the distinction of ACLF from decompensated
cirrhosis
. Due to the increased prevalence of HIV/HCV co-infection in the African American 1945 to 1965 birth cohort and the fact that both are risk factors for chronic liver disease and NHL we postulate that the incidence of NHL presenting as ACLF may increase.

The association of Non-Hodgkin lymphomas and Hepatitis C virus is well documented and antiviral treatments facilitate a virological and hematological response in the majority of HCV related Non-Hodgkin lymphomas. The recent years, direct acting antivirals have made cure possible almost for every HCV patient. Some concerns were raised as regards the frequency and the pattern of recurrence in HCV patients with HCC, treated with these agents. We present a patient with
DLBCL
, in remission after appropriate treatment, HCV
cirrhosis
that was cured with the new antivirals and shortly after SVR, he experienced a lethal lymphoma recurrence.
