Non-Hodgkin's lymphoma (NHL) is a lymphoproliferative disorder, from a subgroup of heterogeneous hematologic malignancies; the term "extranodal" refers to malignant involvement of tissues other than lymph nodes, tonsils, spleen, pharyngeal lymphatic ring, or thymus. Only 0.6% of all NHL are at mandible alone, and it may involve the inferior alveolar canal. We describe a case of bilateral enlarg...

PURPOSE Hyperhomocysteinemia is associated with carcinogenesis. Since only little research exists on hyperhomocysteinemia and malignancy in children, the possible relationship between homocysteine and childhood malignancies remains unknown. The aim of the present study was to determine the serum levels of homocysteine, folic acid and vitamin B12 in children with malignant and benign tumors prio...

Malignant Catarrhal Fever (MCF) is a fatal lymphoproliferative disease of cattle and other ungulates caused by alcelaphine herpesvirus 1 (AlHV-1) ovine 2 (OvHV-2), the main causative agents wildebeest-associated MCF (WA-MCF) sheep-associated (SA-MCF), respectively. The virus mainly spread aerosols from pregnant or newborn sheep, goats, wildebeest to susceptible animals. This case report present...

BACKGROUND The only known risk factor for chronic lymphocytic leukaemia (CLL) is occurrence of the disease in close relatives. The aim of this study was to determine the frequency of familial chronic lymphocytic leukaemia. MATERIAL AND METHOD All patients with chronic lymphocytic leukaemia notified to the Cancer Registry in the period 1.10.2007-31.12.2009 were asked to report occurrences of m...

The most frequent ocular adnexal tumors and simulating lesions are lymphoproliferative disorders (LPDs), including malignant lymphomas and orbital inflammation with lymphoid hyperplasia or infiltration. IgG4-related orbital inflammation (IgG4-ROI) often involves lacrimal glands and other orbital tissues and is an important differential diagnosis. The present study evaluated clinical aspects of ...

Purpose. This review summarizes the more prevalent soft tissue tumours arising in the retroperitoneum and highlights some recent fundamental and diagnostic developments relevant to mesenchymal tumours.Discussion. The retroperitoneum is an underestimated site for benign and malignant neoplastic disease, and represents the second most common site of origin of primary malignant soft tissue tumours...

Malignant B-1 cells derived from NZB mice, a murine model of spontaneous autoimmunity and B cell lymphoproliferative disease, produce significantly higher levels of IL-10 mRNA than normal B-1 or B cells. IL-10 may act as an autocrine growth factor for the expansion of malignant B-1 cells. In order to determine if elevated endogenous production of IL-10 was a required element for the malignant t...
