[Two pelvic tumors which should not be operated, lymphoma of Burkitt and actinomycosis].
ABSTRACT The treatment of the pelvic tumors depends of their histological nature. Some of them require only one medical treatment without recourse to surgery. We report two rare cases of pelvic tumors occurring in young adults. For the first case, actinomycosic nature was related to the histological study of the surgical biopsies. Concerning the second case, the lymphatic nature of a tumor of the low rectum was retained on the immunohistochimic study of the endoscopic biopsies. The evolution was uneventful in the two cases after a medical treatment containing penicillin G or a chemotherapy. We discuss at the time of these two observations the diagnostic difficulties and the therapeutic methods of these rare affections.

ABSTRACT: This review will begin with a detail of the revision of the WHO classification, and pathological definitions of Burkitt lymphoma. Over the past several years, molecular understanding of Burkitt lymphoma has improved significantly. Using gene expression profiling, a genomic "signature" of Burkitt lymphoma may be identified, that has fidelity beyond c-myc expression, and the presence of the classical t(8;14). Then, evaluation and therapy of the adult patient with Burkitt lymphoma will be reviewed. Relatively few data exist on optimal therapy of the adult patient with Burkitt lymphoma. Principles of therapy should include high doses of alkylating agents, frequent administration of chemotherapy, and attention to central nervous system (CNS) prophylaxis with high doses of systemic chemotherapy, intrathecal therapy, or both. The outcome of adult patients with Burkitt lymphoma, particularly those over 40 years of age, is inferior to the outcome of younger patients, but may be improving over the past few years. Results from an international collaborative effort, which are helpful in evaluating results of Burkitt lymphoma therapy in adults, will be presented. HIV-associated Burkitt lymphoma, and elderly patients with Burkitt lymphoma, comprise special clinical situations that will be also covered in this review.Hematology 02/2008; · 2.86 Impact Factor

ABSTRACT: Background. – Rectal tumors are rare in childhood and among them malignant tumors are even less common. Only eight cases of primary rectal lymphomas were reported in children, with various presenting signs and histology. Burkitt’s lymphomas are among these cases.Case report. – A five-year-old child presented with hematochezia and unusual constipation. The rectal examination showed a voluminous intra rectal mass. Radiographic and pathologic examinations led to the diagnostic of Burkitt’s lymphoma with medullary involvement. Complete remission was obtained after initial chemotherapy but a local relapse occurred and the child died eight months later.Conclusion. – Hematochezia associated with unusual constipation impose a rectal examination. Early diagnosis of a rectal tumor may allow patients survival.Archives de Pédiatrie 10/2002; 9(10):1056-1058. · 0.41 Impact Factor

ABSTRACT: Over the past two decades, dramatic improvements in the treatment of children with Non-Hodgkin's Lymphoma have led to cure rates close to 90%, even in advanced-stage disease. The most frequent localization is abdominal, where Burkitt or Burkitt-like subtypes are predominant. Initial management often occurs in the setting of a urgent surgical intervention where multiple complications may gravely threaten prognosis within days or even hours.The SFCE Lymphoma Committee's guidelines for optimal management include: 1) The diagnosis of lymphoma should be systematically evoked whenever the clinical context is not consistent with idiopathic intussusception, particularly in children over the age of 3 or when clinical and/or ultrasound findings are not typical; 2) Limited bowel resection should be performed only if it allows complete tumor removal and is technically simple without extensive dissection or risk of major complications; 3) If surgical resection is likely to be difficult, risky, or incomplete, surgery should be limited to sampling of peritoneal fluid and tumor; 4) In all cases, adequate tissue should be obtained and sent to the pathology department in appropriate media Analysis of tumor material may require, in addition to histology and cytology, immunophenotyping, cytogenetics, and molecular biology studies in order to arrive at an accurate diagnosis and prognosis and to guide treatment choices.Journal de Chirurgie 10/2008; 145(5):454-458. · 0.50 Impact Factor
