Daniele Bernardi, Emanuele Asti, Luigi Bonavina
Ileocolic intussusception due to Burkitt lymphoma is extremely rare in adults. A man aged 17 years presented with a history of recurrent abdominal pain over the past 3 weeks. The abdomen was distended with diffuse tenderness, and bowel sounds were present. Abdominal ultrasound and CT scans showed evidence of small bowel obstruction with marked wall thickening in the ileocecal region and 'target' signs suggestive for intussusception. At laparoscopy, a mass involving the caecum and the terminal ileum was found, along with multiple locoregional nodes, which was highly suggestive of malignancy...

The non-Hodgkin lymphomas (NHLs) occurring in children and adolescents and young adults (AYA) are characterized by various age-related differences in tumor biology and survival. Children generally present with high-grade lymphomas, such as Burkitt lymphoma, diffuse large B-cell lymphoma, lymphoblastic lymphoma, and anaplastic large cell lymphoma, whereas low-grade histologic subtypes, such as follicular lymphoma, occur more frequently with increasing age. Treatment outcome for children with NHL is generally superior to that observed in adults...

Characteristic chromosomal translocations are found to be associated with subtypes of B-cell non-Hodgkin lymphoma (NHL), for example t(8;14)(q24;q32) and Burkitt lymphoma, t(14;18)(q32;q21) and follicular lymphoma, and t(11;14)(q13;q32) in mantle cell lymphoma. Only few recurrent cytogenetic aberrations have been identified in the T-cell NHL and the best known is the ALK gene translocation t(2;5)(p23;q35) in anaplastic large cell lymphoma. Since lymph node or other tissue is seldom submitted for conventional cytogenetics study, alternative approaches for translocation detection are polymerase chain reaction (PCR) or fluorescence in situ hybridization (FISH)...

Intramolecular circularization of DNA oligonucleotides was accomplished by incorporation of alkyne-modified photolabile nucleosides into DNA sequences, followed by a Cu(I) -catalyzed alkyne-azide cycloaddition with bis-azido linker molecules. We determined a range of ring sizes, in which the caged circular oligonucleotides exhibit superior duplex destabilizing properties. Specific binding of a full-length 90 nt C10 aptamer recognizing human Burkitt's lymphoma cells was then temporarily inhibited by locking the aptamer in a bicircularized structure...

BACKGROUND: Lymphoma is one of the most common pediatric malignancies; however, there are few well-established risk factors. Therefore, we investigated if maternal and perinatal characteristics influenced the risk of childhood lymphoma. PROCEDURE: Information on cases (n = 374) diagnosed with lymphoma and born in Texas for the period 1995-2011 was obtained from the Texas Cancer Registry. Birth certificate controls were randomly selected at a ratio of 10 controls per 1 case for the same period of 1995-2011...

Lymphoma of the eyelid constitutes 5% of ocular adnexal lymphoma. In previously published cases, 56% of lymphomas of the eyelid are of B-cell origin and 44% are of T-cell origin. The most frequent B-cell lymphomas are extranodal marginal zone lymphoma (27 cases--14%) and diffuse large B-cell lymphoma (18 cases--9%). T-cell lymphomas are most frequently mycosis fungoides (25 cases--13%), extranodal NK/T-cell, nasal type lymphoma (12 cases--6%) and primary cutaneous anaplastic large cell lymphoma (12 cases--6%)...

The steroid Na+/K+-ATPase blocker ouabain has been shown to exhibit cytotoxic effects in various tumor cell systems. This study aimed to determine the effects of ouabain on Burkitt's lymphoma Raji cells. Ouabain treatment of Raji cells significantly inhibited cell proliferation in a dose-dependent manner and increased the morphological changes associated with apoptosis. Additionally, increased numbers of both early and late apoptotic cells were observed by annexin V-FITC/PI flow cytometry assay. Increased levels of caspase-3 and cleaved-caspase-3, higher Bax activity and decreased expression of the anti-apoptotic protein Bcl-2 were detected in ouabain-treated Raji cells...

CASE PRESENTATION: A 35-year-old woman without any known systemic disorder presented with a complaint of painful and rapidly increasing proptosis in her right eye. Based on the clinical, radiological, analytical and ophthalmological assessments, the diagnosis made was Burkitt's lymphoma in acquired immunodeficiency syndrome. CONCLUSION: Proptosis can be an unusual way of presenting with Burkitt's lymphoma associated with acquired immunodeficiency. This differential diagnosis is important because confirmation leads to a change in the vital prognosis of the patient...

Burkitt lymphoma is the most common malignancy in children in Malawi, the world's poorest country, where there is a long history of treating this disease using a 28-day cyclophosphamide-based protocol. Stage III/IV disease has had poor outcomes. In an attempt to improve the outcome for higher stage disease, anthracyclines were added to the existing protocol. The disease-free (DFS) and overall survival (OS) of 58 children with cytologically confirmed Burkitt lymphoma admitted during 2012-2014 and treated using this protocol were calculated...

Because of its rarity and high curability, progress in advancing therapeutics in Burkitt lymphoma (BL) has been difficult. Over recent years, several new mutations that cooperate with MYC have been identified, and this has paved the way for testing novel agents in the disease. One of the challenges of most standard approaches typically used is severe treatment-related toxicity that often leads to discontinuation of therapy. To that point, there has been recent success developing intermediate intensity approaches that are well tolerated in all patient groups and maintain high cure rates in a multicenter setting...

Numb chin syndrome, also known as mental nerve neuropathy, is a rare sensory neuropathy characterized by paresthesia and hypoesthesia in the area supplied by the mental nerve and its branches. This syndrome may be the first symptom of underlying malignancy or the first sign of recurrence and metastasis in patients with preexisting cancer. In this article, we present two cases with bilateral numb chin syndrome as the first manifestation of Burkitt's lymphoma/leukemia and review the relevant literature. Numb chin syndrome should be considered as a warning sign and raise the suspicion for an underlying malignancy...

Autoimmune hemolytic anemia (AIHA) in childhood, including paroxysmal cold hemoglobinuria, is an uncommon, potentially life-threatening disorder. AIHA is a recognized complication of several varieties of lymphoproliferative disorders, including high-grade B-cell lymphoma, but it has not been associated with Burkitt lymphoma in people without an underlying immunodeficiency. When AIHA occurs in association with lymphoproliferative disorders, it may precede or accompany the diagnosis of malignant disease or herald relapse...

BACKGROUND: Pediatric patients with non-Hodgkin lymphoma (NHL) in developing countries (DCs) present with greater tumor load even at lower stages and with comorbidities that impact therapy delivery. This causes toxic mortality with "standard" intensive protocols or recurrences with "gentler" treatment. OBJECTIVES: We developed and evaluated a risk stratification schema that guides intensity of therapy. DESIGN/METHODS: Sixty-nine patients were prospectively assigned to five risk groups (A-E; n = 6, 15, 16, 15, and 17) following staging and treated with protocols of risk-stratified intensity...

Epstein-Barr virus (EBV) infection is associated with several distinct hematological and epithelial malignancies, e.g., Burkitt lymphoma, Hodgkin lymphoma, nasopharyngeal carcinoma, gastric carcinoma, and others. The association with several malignant tumors of local and worldwide distribution makes EBV one of the most important tumor viruses. Furthermore, because EBV can cause posttransplant lymphoproliferative disease, transplant medicine has to deal with EBV as a major pathogenic virus second only to cytomegalovirus...

Cancer has been recognized for thousands of years. Egyptians believed that cancer occurred at the will of the gods. Hippocrates believed human disease resulted from an imbalance of the four humors: blood, phlegm, yellow bile, and black bile with cancer being caused by excess black bile. The lymph theory of cancer replaced the humoral theory and the blastema theory replaced the lymph theory. Rudolph Virchow was the first to recognize that cancer cells like all cells came from other cells and believed chronic irritation caused cancer...

Leukotrienes (LTs) are inflammatory mediators that play a pivotal role in many diseases like asthma bronchiale, atherosclerosis and in various types of cancer. The key enzyme for generation of LTs is the 5-lipoxygenase (5-LO). Here, we present a novel putative protein isoform of human 5-LO that lacks exon 4, termed 5-LOΔ4, identified in cells of lymphoid origin, namely the Burkitt lymphoma cell lines Raji and BL41 as well as primary B and T cells. Deletion of exon 4 does not shift the reading frame and therefore the mRNA is not subjected to non-mediated mRNA decay (NMD)...
