Burkitt's lymphoma is a malignant endemic neoplasia with a mandibular localization, described for the first time in 1958, in African children. The World Health Organization classification recognises several variants of Burkitt's lymphoma; all are highly malignant B cell lymphomas. Besides Burkitt's sporadic, endemic lymphoma and Burkitt's lymphoma associated with AIDS, the World Health Organiza...

Primary malignant lymphoma of the female genital tract, a rare form of extranodal non-Hodgkin's lymphoma (NHL), can occur in the ovary, uterine corpus, cervix, vagina, and vulva. The ovary is the most frequent site for NHL involvement of the gynecological tract (Vang et al., 2001). Primary malignant lymphoma of the cervix is a rare disease. The incidence is unknown. In 1974, Chorlton et al. rep...

Follicular lymphoma is a low grade malignant lymphoma. However, some follicular lymphomas undergo histological transformation into higher grade malignant lymphomas. We recently encountered a diffuse large cell lymphoma which seemed to have progressed from a follicular lymphoma and which finally transformed into a small non-cleaved lymphoma. Each stage of the histological transformation was acco...

The majority of malignant tumors of the stomach are carcinomas. It has been reported in the literature that lymphomas consist of 1%-5% of all malignant tumors of the stomach (1). The simultaneous coexistence of adenocarcinoma and malignant lymphoma of the stomach is extremely rare (1-5). Gastric carcinoma and primary gastric lymphoma have shown to be related to Helicobacter pylori infection (3)...

for approximately 3% of primary malignant bone tumors and for 5% of extranodal lymphoma (1). In the majority of cases, the tumor involves the extremities and less frequently the axial skeleton. Disseminated malignant lymphoma is extremely rare, representing 0.8% of malignant non-Hodgkin’s lymphoma(NHL) (2). Here, we encountered primary NHL of bone involving the skull, spine, both upper and lowe...

Cold agglutinin disease (CAD) is a well-recognized complication of lymphoproliferative disorders. It has been previously recognized that cases of primary CAD frequently exhibit underlying malignant lymphoma in the bone marrow. Lymphoplasmacytic lymphoma is the most common subtype of malignant lymphoma; however, diffuse large B-cell lymphoma (DLBCL) has also been documented, albeit extremely rar...

Lymphomas are a heterogenous group of malignant diseases. 30-50% of patients, even before chemo- and radiotherapy are begun have anemia. The pathogenesis of this anemia is multifactorial and still not completely clear. Newer investigations refer to a causality between the anemia in patients with lymphoma and the inappropriate erythropoietin production for the degree of anemia. Based on this fin...

BACKGROUND Yersinia pseudotuberculosis generally infects the gastrointestinal tract and causes enteropathy symptoms suggesting infection. Y. pseudotuberculosis infections are often complicated with intraceliac lymphoadenopathy mimicking malignant lymphoma. This is a first case of Yersinia pseudotuberculosis enteropathy mimicking enteropathic γδ T-cell lymphoma. This case highlighted the γδ T-ce...

Non-Hodgkin lymphoma (NHL) represents the third most common group of malignant lesions of the oral cavity, following squamous cell carcinomas and salivary gland neoplasms. It accounts for 3-5% of all malignant lesions of the oral cavity [1]. Further, only 1% of all lymphomas are primary oral cavity lymphoma. Non-Hodgkin’s lymphoma of the tongue is extremely rare. It can arise from Waldeyer’s ri...
