Patients with indolent non-Hodgkin lymphomas (NHL) may often be followed up only with observation, reserving chemotherapy in case of spread. Patients with chronic HCV infection and B cell NHL frequently undergo regression of lymphoproliferative disease once HCV infection is eradicated by treatment. Interferon (IFN)-based therapy has been the treatment of choice for years, remaining unclear whether it is effective in B cell NHL directly or through HCV eradication, since IFN is effective in both HCV infection and B cell NHL. IFN therapy for HCV infection became obsolete with the advent of the well tolerated direct-acting antiviral agents (DAAs), whose excellent efficacy in treating patients with chronic HCV infection and B cell NHL has been recently highlighted. We treated a 53-year-old woman with chronic HCV infection and marginal zone lymphoma (MZL) with elbasvir plus grazoprevir in 2018, with complete remission and persisting excellent results: sustained virological response 24 weeks after treatment (SVR24). The exclusive role of HCV eradication in B cell NHL regression is also underlined.

Primary lymphoma of the female genital tract is very rare. We report the case of a 36-year-old woman who was referred to our hospital because of an indeterminate Pap smear test. The colposcopy showed a thickening of the posterior vaginal wall and various irregular ulcerated nodular lesions. Histological examination, immunohistochemistry and the staging procedures were conclusive of diffuse large B-cell lymphoma of the vagina, stage IEA. Complete remission was achieved after 6 cycles of immunopolychemotherapy (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone). No relapse has occurred during a follow-up of 71 months. Moreover, we reviewed the 62 previously reported cases of primary extranodal non-Hodgkin's lymphoma of the vagina, focusing on clinicopathological and therapeutic aspects, to better characterize this unusual disease., (Copyright © 2012 S.

Aims: To evaluate changes in Hepatitis C Virus (HCV) RNA both in plasma and Peripheral Blood Mononuclear Cells (PBMC) in onco-haematological patients., Patients and Methods: 8 consecutive anti-HCV/HCV RNA-positive patients with onco-haematological diseases (5 with B-cell Non-Hodgkin Lymphoma and 3 with chronic lymphocytic leukaemia) were observed during chemotherapy and after its discontinuation. All were naïve to chemotherapy. HCV RNA was sought by Real Time Polymerase Chain Reaction in Light Cycler 1.5 in plasma and PBMC samples collected before, during and after chemotherapy., Results: An increase in HCV RNA of at least 1.5 log IU/mL in plasma and 1.1 log IU/ml in PBMC was observed in all 7 patients undergoing Rituximab-based chemotherapy; these patients showed a hepatic flare after discontinuation, life-threatening in one with cirrhosis. Also the 8th patient had cirrhosis, but was treated with Rituximab-sparing chemotherapy and did not show any increase in HCV RNA or a hepatic flare., Conclusion: Rituximab-based chemotherapy favours an increase in HCV RNA in onco-haematological patients; this is followed by a hepatic flare, possibly immune-mediated and life threatening in cirrhotic patients., (Copyright © 2011.

We report a case of primary non-Hodgkin lymphoma of the breast as third metachronous neoplasm in the same patient. Primary non-Hodgkin lymphoma of the breast occurred about 2 years after endometrial cancer and 1 year after bladder cancer. The patient underwent quadrantectomy with level I-II axillary lymph nodes dissection plus rituximab-cyclophosphamide, doxorubicin, vincristine, prednisone chemotherapy. Patient's health status gradually got worse and 11 months after surgery the patient died.
