A challenging diagnosis of plasmablastic lymphoma: importance of integrating morpholgy immunohistochemistry and flow cytometry findings (case report).

Plasmablastic lymphoma (PBL) is a rare clinicopathological entity that still raises many diagnostic and management difficulties, particularly due to the overlap between plasmablastic lymphomas and myeloma features. We report a clinical presentation of PBL affecting bone marrow in a 43-year-old patient who was admitted for B symptoms, hepatosplenomegaly, and bicytopenia investigation. Based on these findings, acute leukemia was suspected.

A novel t (5; 17) (q35; q21) associated with t (8; 21) (q22; q22) in a patient with acute myeloid leukemia: case report and review of literature.

The t (8; 21) (q22; q22) with the resulting RUNX1- RUNX1T1 rearrangement is one of the most common cytogenetic abnormalities in acute myeloid leukemia (AML). It is associated with favorable prognosis. The t (5; 17) (q35; q21) is an uncommon translocation, fuses the gene for the nucleophosmin (NPM) to the retinoic acid receptor α(RARA) and was described essentially in acute promyelocytic leukemia (APL) variant.

Panniculitis in a Woman With Opportunistic Pulmonary Coinfection by Pneumocystis jirovecii and Cryptococcus neoformans: 18F-FDG PET/CT Revealing the Infection and Assessing Treatment Response.

A 56-year-old woman, with history of psoriasis well controlled on ustekinumab, underwent 18F-FDG PET/CT to explore first onset of histologically proven skin panniculitis of unknown origin. PET/CT showed high uptake in panniculitis lesions in limbs and in a lung opacity suggestive of pneumonia. Based on PET/CT findings, a bronchoalveolar lavage revealed pulmonary coinfection by Pneumocystis jirovecii and Cryptococcus neoformans.

Oral Lichen Planus and Polycythemia: Possible Association.

Oral lichen planus is a chronic inflammatory disease of established immune-mediated pathogenesis that affects the oral mucosa. Polycythemia is a nonaggressive myeloproliferative disorder, characterized by an increase in red blood cell mass, often with uncontrolled production of granulocytes and platelets. Their association was rarely mentioned in the scientific literature.

Positron-emission tomography-guided radiation therapy: Ongoing projects and future hopes.

Radiation therapy has undergone significant advances these last decades, particularly thanks to technical improvements, computer science and a better ability to define the target volumes via morphological and functional imaging breakthroughs. Imaging contributes to all three stages of patient care in radiation oncology: before, during and after treatment. Before the treatment, the choice of optimal imaging type and, if necessary, the adequate functional tracer will allow a better definition of the volume target.

IKZF1 genetic variants rs4132601 and rs11978267 and acute lymphoblastic leukemia risk in Tunisian children: a case-control study.

Background: Associations between IKZF1 gene variants and Acute Lymphoblastic Leukemia (ALL) was recently reported. We examined whether the common IKZF1 polymorphisms rs4132601 T/G and rs111978267 A/G are associated with ALL among a Tunisian pediatric cohort.

Methods: This case-control study involved 170 patients with ALL and 150 control subjects.

Methods And Results: Men with BMI ≥ 25 and women referred for MPS were considered for inclusion. All individuals underwent 99m-Tc-SPECT-MPS with CZT cameras and 82-Rb-PET-MPS in 3D-mode.

Meningococcemia complicated by myocarditis in a 16-year-old young man: a case report.

Fulminant meningococcemia is a relatively rare life-threatening disease caused by Neisseria meningitidis. The clinical presentation is varied, but, when associated with myocarditis, it carries a particularly poor prognosis. We report a case of a patient with fulminant meningococcemia who subsequently developed severe myocardial dysfunction and successfully recovered within a period of 7 days of hospitalization.

Biological control of Meloidogyne javanica on tomato with Dazitol® and soil solarization.

Pot and greenhouse trials were conducted for the management of root-knot nematode, Meloidogyne javanica, infestation in tomato. Growth parameters, gall index, soil, and root nematode populations were measured to assess the effect of a novel bio-pesticide (Dazitol®), made from mustard oil and oleoresin of Capsicum, on plant growth and nematode reproduction. Data generated within the pot experiment showed that the tested bio-pesticide did not improve plant growth, but it reduced significantly root-knot nematode damage resulting in a decrease in gall index and root (91%) and soil (62%) population of M.

First report of associated with apple in Tunisia.

The root-lesion nematode of the genus Filipjev (1936) has a worldwide distribution and cause severe production constraints on numerous important crops. In 2013-14, during a survey of the apple nurseries and orchards in center of Tunisia (Kairouan, Zaghouan, Monastir and Kasserine), 70 different roots and soil samples were collected. The populations of root-lesion nematode were identified on the basis of their morphological and morphometric characters, and by molecular methods.

Success of anti-CD20 monoclonal antibody treatment for severe autoimmune hemolytic anemia caused by warm-reactive immunoglobulin A, immunoglobulin G, and immunoglobulin M autoantibodies in a child: a case report.

Background: Autoimmune hemolytic anemia is rare in children. First-line therapies for this disease consist of corticosteroids and intravenously administered immunoglobulin that are effective in most patients. However, a small proportion of cases (5 to 10%) is refractory to these therapies and may represent a medical emergency, especially when hemolysis is due to warm immunoglobulin M.

The efficacy of Verticillium leptobactrum isolate (HR1) was evaluated in the control of root-knot nematode and Fusarium wilt fungus under laboratory and greenhouse conditions. Five concentrations of V. leptobactrum (HR1) isolate were tested for their nematicidal and fungicidal activities against Meloidogyne javanica and Fusarium oxysporum f.

[Primary osseous Hodgkin's lymphoma of the sacrum: A diagnostic and therapeutic challenge].

Primary osseous Hodgkin's lymphoma is a very rare entity. Cases reported in the literature are limited with often insufficient initial exploration. We report a new case of a 24 years old patient with a diagnosis of primary osseous Hodgkin lymphoma of the lumbosacral region with extension to the soft tissues, without simultaneous lymph node involvement confirmed both by conventional and metabolic imaging.

Minimal residual disease detection in Tunisian B-acute lymphoblastic leukemia based on immunoglobulin gene rearrangements.

IGH gene rearrangement and IGK-Kde gene deletion can be used as molecular markers for the assessment of B lineage acute lymphoblastic leukemia (B-ALL). Minimal residual disease detected based on those markers is currently the most reliable prognosis factor in B-ALL. The aim of this study was to use clonal IGH/IGK-Kde gene rearrangements to confirm B-ALL diagnosis and to evaluate the treatment outcome of Tunisian leukemic patients by monitoring the minimal residual disease (MRD) after induction chemotherapy.

[Juvenile myelomonocytic leukemia: A three-case series].

Juvenile myelomonocytic leukemia (JMML), previously known as juvenile chronic myeloid leukemia (JCML), is a rare, myelodysplastic-myeloproliferative disease typically presenting in early childhood. This disorder is difficult to distinguish from other myeloproliferative syndromes such as chronic myeloid leukemia (CML) because of the similarities in their clinical and bone marrow findings. However, because of its unique biological characteristics such as absolute monocytosis with dysplasia, absence of Philadelphia chromosome or BCR-ABL fusion protein, hypergammaglobulinemia, and raised fetal hemoglobin level, this disorder does not satisfy the criteria for inclusion in the CML or chronic myelomonocytic leukemia (CMML) group, as seen in adult patients.
