Introduction: Neurological manifestations during Waldenstrom disease are common and are usually related to immune peripheral neuropathy or serum hyperviscosity syndrome. The infiltration of the central nervous system by the lymphoproliferative syndrome is known as the Bing-Neel syndrome. This extremely rare entity remains poorly described in the literature., Case Reports: We report on 4 cases of patients for whom central neurological disorders led to the diagnosis of a Bing and Neel syndrome. These four cases illustrate different clinical presentations, diagnosis, therapeutic options, and outcome in this syndrome. Based on our literature review, we discuss about these differences., Conclusion: The polymorphic clinical manifestations of Bing and Neel syndrome can mimic many diagnoses. However, it may be necessary to consider this diagnosis. Cerebrospinal fluid analysis and MRI may allow rapid diagnosis or guide a biopsy. Prolonged remissions are possible with appropriate treatment., (Copyright © 2014 Société nationale française de médecine interne (SNFMI). Published by Elsevier SAS. All rights reserved.)

We report a 49-year-old man suffering from chronic hypereosinophilia whose biological tests revealed a gene rearrangement between FIP1L1 and PDGFRA as well as a T-cell clonality. After 1 year of therapy with imatinib mesylate (100 mg daily), the patient was clinically asymptomatic, the fusion transcript was undetectable using RTQ-PCR and no lymphoproliferative disorders occurred. This unique combination raises the question of the physiopathology of such a grey zone hypereosinophilia and their management., (Copyright © 2010. Published by Elsevier SAS.)

Macrophage activation syndrome (MAS) is a rare immunological disorder, rapidly life-threatening in the absence of specific treatment. Malignant lymphoma is common cause of MAS, but Hodgkin's lymphoma has been rarely associated with MAS. We report a 79-year-old man who presented a MAS as the presenting feature of Hodgkin's lymphoma, with a rapidly fatal outcome. We discuss the usefulness of sCD25 and interleukine 18 assays when diagnosis is difficult to obtain. We also review the literature data related to Hodgkin's lymphoma-associated MAS., (Copyright © 2010 Société nationale française de médecine interne (SNFMI). Published by Elsevier SAS.

Myelodysplastic syndrome with erythroid hypoplasia or erythroblastopenia has not yet been clearly defined, and in most patients it is mistaken for acquired pure red cell aplasia. Including one additional patient reported in this article, a literature review revealed only 50 cases over the last 20 years. These patients were predominantly elderly males, all required regular packed red cell transfusions, and they had a poor prognosis, mainly because of acute transformation. The mechanisms of erythroid aplasia remain unclear. However, recent data suggest the association of an intrinsic stem cell defect with immunological implication., (Copyright © 2010 Société nationale française de médecine interne (SNFMI).

Case Report: The diagnosis of hereditary xerocytosis is made in a 57 year old woman splenectomized 30 years ago for a chronic hemolytic anemia. In following, she developed many thrombophlebitis of lower limbs and portal vein., Discussion: The methods of diagnosis of this rare hereditary stomatocytosis are recalled, and the mechanisms of thrombotic tendency after splenectomy are discussed. This case underlines the fact that splenectomy is banned in the treatment of hereditary stomatocytosis, and that the serious consequences of iron overload, which is very frequent in this disease, must be prevented.

Abdominal pain is uncommon in patient with Epstein-Barr infection and is usually attributed to an enlargement of the liver or spleen. We report on an 8-year-old girl with a pseudoperitonitis due to a mesenteric lymphadenitis associated with Epstein-Barr infection. Outcome was favourable without surgery. We review the different causes of abdominal pain occurring during Epstein-Barr infection.

Introduction: Cytomegalovirus neurological complications are frequent in immunocompromised patients specially in HIV positive patient. In immunocompetent patient these complications are infrequent., Exegesis: We describe a case of cytomegalovirus myeloradiculitis during pregnancy in a 25-year-old woman, HIV negative. The evolution was favorable with foscarnet therapy., Conclusion: A spinal complication during cytomegalovirus infection in immunocompetent patient should lead to a therapy with a specific antiviral to reduce neurologic involvement.

The case of a 50-year-old woman who experienced an acute Streptococcus salivarius meningitis after a spinal anaesthesia for hysteroscopy is reported. The contamination of the cerebrospinal fluid may occur from a puncture during a bacteriaemia. Contamination from the patient's skin and from the upper airway's flora of the operator seems to be a more plausible cause. Spinal anaesthesia is contra-indicated in the febrile patient. Asepsis is essential during spinal puncture, including wearing a surgical face mask.

The authors report two cases of bone marrow aplasia observed 2 months after initiation of a treatment with ticlopidine. The outcome was favorable after discontinuation of therapy. The frequency of this severe drug-induced complication seems to have been underestimated. The absolute necessity of a careful haematological survey during the first 3 months of therapy is pointed out.
