ABSTRACT Primary ovarian non-Hodgkin's lymphoma (PONHL) is an uncommon entity; its pathology is usually diffuse large B cell lymphoma (DLBCL).
We report 3 cases of ovary involvement of DLBCL, 1 of which rapidly developed to central nervous system involvement. Diagnosis and subsequent treatment are discussed and the literature on the origin, epidemiology, clinical presentation, diagnosis, treatment and prognosis of ovary lymphoma are reviewed. All patients were diagnosed as having DLBCL after ovary biopsy, and were subsequently given regular chemotherapy. Two of them obtained remission and 1 of them had central nervous system involvement.
Ovary involvement of DLBCL is rare; prognosis is related to the overall clinical manifestation and some serum biomarkers. Diagnosis is established by ovary biopsy. Inaccurate or delayed diagnosis is often due to the lesions presenting as a mass resembling ovary cancer and may lead to poor outcome. Treatment regimen mainly consists of chemotherapy (CHOP) associated with rituximab. Intrathecal chemotherapy may play an important role in prevention of central nervous system involvement.

    ABSTRACT: Primary ovarian lymphoma is rare. To better understand the clinicopathological and molecular features of these tumours, we studied 14 patients (age range 13 to 74 years, mean 46.9 years) with non-Hodgkin's lymphoma who initially presented with an ovarian tumour. The clinicopathological features were reviewed and tissue samples were studied by immunohistochemistry and for immunoglobulin gene rearrangement, presence of Epstein Barr virus and for MYC and BCL-2 rearrangements by fluorescence in situ hybridisation. The most common symptoms were abdominal pain and abdominal distension. Ten patients had a unilateral (7 left, 3 right) ovarian mass and 4 had bilateral ovarian masses, size range 4 to 13 cm (mean, 7.9 cm). Of the 14 lymphomas, 12 were classified as diffuse large B-cell lymphoma (DLBCL) and 2 as Burkitt lymphoma. The Burkitt lymphomas had a MYC rearrangement. The DLBCLs were of the germinal centre B-cell-like subtype. One DLBCL patient had MYC and BCL2 rearrangements. The treatment consisted of various combinations of surgery, chemotherapy and radiotherapy. The follow-up period ranged from 3 to 56 months. During the follow-up period, 8 patients died of disease, 4 were alive with disease, and 2 were alive without disease. Most primary ovarian lymphomas are of germinal centre B-cell-like subtype DLBCL, which have high proliferative activity and poor prognosis.

    ABSTRACT: Arsenic is a well-known human carcinogen, which potentially affects ~160 million people worldwide via exposure to unsafe levels in drinking water. Lungs are one of the main target organs for arsenic-related carcinogenesis. These tumors exhibit particular features, such as squamous cell-type specificity and high incidence among never smokers. Arsenic-induced malignant transformation is mainly related to the biotransformation process intended for the metabolic clearing of the carcinogen, which results in specific genetic and epigenetic alterations that ultimately affect key pathways in lung carcinogenesis. Based on this, lung tumors induced by arsenic exposure could be considered an additional subtype of lung cancer, especially in the case of never-smokers, where arsenic is a known etiological agent. In this article, we review the current knowledge on the various mechanisms of arsenic carcinogenicity and the specific roles of this metalloid in signaling pathways leading to lung cancer.

    ABSTRACT: The involvement of the ovary in lymphomatous process is rare. Such an involvement may occur in 2 ways, primary or secondary. We report 5 cases of ovarian non-Hodgkin's lymphoma, with 3 of which primarily arising in the ovaries. Ovarian lymphoma can mimic more frequently occurring tumors including advanced epithelial carcinoma and radical surgery may be performed instead of a biopsy. The immunophenotypic and clinicopathologic features exhibited in this small series are described to call attention to early diagnosis and treatment of ovarian lymphoma. All patients were diagnosed as having DLBCL after ovary biopsy. Different treatment modalities were used and prognosis of the patients was reported.
