Leukaemic phase of non-Hodgkin lymphoma (NHL) is characterised by penetration of lymphoma cells from the originating tissues (lymph nodes, less commonly the spleen) into the peripheral blood and bone marrow. The diagnosis of leukaemic phase of Mantle zone lymphoma is established on the basis of histological findings of lymph node biopsy and, possibly, the spleen, peripheral blood smear, and characteristic membranous phenotype. A patient, aged 60, is reported with Mantle zone (intermediate lymphoma) in leukaemic phase. Physical examination revealed pallor of the skin, generalized lymphadenopathy, and hepatomegaly. WBC count in the peripheral blood was 22.5 x 109/l, and the smear revealed the presence of pleomorphic lymphoid cells, mainly medium sized, with irregular nucleus or nuclear notches. Immunophenotype studies of mononuclear cells of the peripheral blood showed characteristic membranous phenotype for Mantle zone lymphoma in leukaemic phase: Smlg+ (lambda light chain); HLA-DR+; CD19+; CD22+; CD5+; CD10-; CD25-. Pro-MACE-Cyta-bom protocol was applied resulting in a 13-month-lasting remission. The total survival was 20 months, suggesting poor prognosis of leukaemic phase of Mantle zone lymphoma.

Modern intensive chemotherapy regimens have improved the prognosis for adult patients with acute lymphocytic leukemia (ALL). With these regimens, the complete response (CR) rates are approximately 75% and long-term disease-free survival (DFS) rates are about 20-35%. For patients with high-risk ALL, DFS rates are only 20% or less. Hyper-CVAD regimen is effective in ALL and aggressive non-Hodgkin lymphomas (NHL) with increased CR rates and DFS rates. Between June 2002 and October 2006, 53 consecutive adult patients with newly diagnosed adult ALL were treated with Hyper-CVAD regimen for six to eight cycles. The alternating courses were given every 3-4 weeks or earlier if count recovery occurred. CR rates of 73.6% were achieved in 39 patients, the estimated 2-year survival rate was 82.9% and the estimated 2-year event-free survival (EFS) rate was 87.3%. Side effects were as expected, mostly attributed to myelosuppression. Analysis of prognostic factors suggested that some previously well-established poor prognostic factors such as the degree of leukocytosis and central nervous system (CNS) or testicular involvement were less important with this dose-intensive regimen. However, patients with mediastinal disease had lower CR rates (P<0.05), with the presence of hepatomegaly and t(9;22) abnormalities had poor survival (P<0.05). Compared with other established adult ALL regimens, Hyper-CVAD regimen was associated with significantly better CR rates, overall survival and EFS rates. The long-term follow-up results of Hyper-CVAD were favorable.

We report the case of a 22-year-old woman who presented with acute onset flaccid quadriparesis. Physical examination showed mild pallor with cervical and axillary lymphadenopathy, hepatomegaly, and bilateral smooth enlarged kidneys. Neurological examination revealed lower motor neuron muscle weakness in all the four limbs with hyporeflexia and normal sensory examination. Laboratory investigations showed anemia, severe hypokalemia, and metabolic acidosis. Urinalysis showed a specific gravity of 1.010, pH of 7.0, with a positive urine anion gap. Ultrasound revealed hepatosplenomegaly with bilateral enlarged smooth kidneys. Renal biopsy was consistent with the diagnosis of non-Hodgkin lymphoma (B cell type). Metabolic acidosis, alkaline urine, and severe hypokalemia due to excessive urinary loss in our patient were suggestive of distal renal tubular acidosis. Renal involvement in lymphoma is usually subclinical and clinically overt renal disease is rare. Diffuse lymphomatous infiltration of the kidneys may cause tubular dysfunction and present with hypokalemic paralysis.

Immunocytoma is a non-Hodgkin's indolent evolution B cell lymphoma. It accounts for approximately 1-3% of non-Hodgkin's limphomas and usually onsets in adults aged over 50 years old. It manifests as lymphadenopathy, splenomegaly, hepatomegaly and lymphcytosis in 15 -30% of cases and is rarely seen with pulmonary involvement. Monocloncal peaks of serum immunoglobulin often occur. These are IgM and rarely IgA. We present as an example a male patient aged 52 years old, with recurrent respiratory infections. Clinical work -up identified an immunocytoma IgA stage IV. Diagnosing an indolent lymphoma, we prophylactic polyspecific human immunoglobulin to treat the respiratory infection. Evidence of lymphoma progression leads us to prescribe combined cyclo- phosphamide (C), vincristine (V), prednisone (P) e rituximab (R) (CVP-R), which has obtained a partial response over two years.

This study evaluates the clinical and laboratory data of children with secondary hemophagocytic lymphohistiocytosis (sHLH) related to malignancy. Charts of patients who met the diagnostic criteria for sHLH associated with malignancy between January 2000-2006 at six different hospitals in Turkey were reviewed retrospectively. The diagnosis of HLH had been established by bone marrow aspiration in 27 patients, cerebrospinal fluid and bone marrow aspiration in one patient and lung-liver biopsy in another. Twenty-nine children were diagnosed as having sHLH related to malignancy. Twenty cases (18 ALL and 2 AML) with acute leukemia (10 girls/10 boys, median age: 8 years [3-14 years]) were found to have sHLH. Five patients with acute leukemia had HLH at the time of diagnosis (Group 1a), and 15 patients with acute leukemia were diagnosed as having sHLH during therapy (Group 1b), namely reactive sHLH associated with the chemotherapy. Nine patients, including two cases each of rhabdomyosarcoma, neuroblastoma, Hodgkin disease, and non-Hodgkin lymphoma (NHL) and one case with Langerhans cell histiocytosis, were diagnosed as having concomitant hemophagocytosis at the initial evaluation of the tumor (Group 2). Fever, anemia, and hypertriglyceridemia were present in all sHLH cases of all three groups. Hepatomegaly was detected in 60.0%, 73.3%, and 88.8% of the three groups, respectively. Splenomegaly was more frequent in patients of Groups 1a (60.0%) and 2 (88.8%) than in those of Group 1b, the reactive ones (13.3%). Hypofibrinogenemia was detected in all patients of Group 1a and Group 2. Low level of fibrinogen was present in 91.6% of patients in Group 1b. All patients in Group 1b (100%) had neutropenia and thrombocytopenia. Neutropenia was found at rates of 60.0% and 55.5% in Group 1a and Group 2, respectively. Thrombocytopenia was detected in 80.0% of patients in Group 1a and 77.7% in Group 2. The overall mortality rate was 34.4% (10 cases) in our series of 29 children with sHLH; 50% of deaths were directly attributable to HLH. Pediatric malignancy-associated HLH patients have been commonly described as case presentations or in a review of the literature. We believe that our cohort, compiling 29 children regarding the association between malignancy and HLH, will be useful for pediatricians who are interested in this still mysterious topic.

We present the case of a 65 years old male, admitted in the Hematology Department of the Universitary Emergency Hospital Bucharest, complaining of physical asthenia and weight loss; periodical medical examination has revealed splenomegaly and leucocytosis with lymphocytosis, persistent for the past 3 years. The clinical and paraclinical exam demonstrated splenomegaly (21 cm in diameter on computer tomography scan), hepatomegaly and generalized lymphadenopathies. The laboratory tests confirmed leucocytosis with lymphocytosis--a clonal population of B lymphocytes CD20+ CD19+ CD23+/- CD79b+(low), CD43+ FMC7+ CD5+ CD38+ ZAP70+ cyclin D1-. Lymph node and bone marrow biopsy together with flowcytometry established the diagnosis of Malignant non-Hodgkin Lymphoma--Atypical Splenic Marginal Zone B-cell lymphoma (aberrant expression of CD5) stage IVB, with leukemic picture, complicated with autoimmune hemolytic anemia with highly positive Coombs' tests. We performed therapeutic splenectomy, which was difficult because of the dimensions of the organ. The short term evolution was complicated by acute complete thrombosis of the splenic vein, but the long term evolution (1 year follow-up) was favorable--remission of anemia, significant improvement of performance status, decrease of leucocytosis and reduction of the tumoral mass.

Hemophagocytic syndrome (HS) is a life-threatening condition of hyperinflammation. Main symptoms are: prolonged fever, cytopenia, hepatosplenomegaly, hemophagocytosis, hyperferritinemia, hypertriglyceridemia and hypofibrinogenemia. Primary genetic form and secondary HS associated with infections, malignancies or autoimmune disorders can be distinguished. Untreated HS in most cases leads to death. We analyzed retrospectively 7 cases of HS in children (3 girls, 4 boys; aged 10 days -14 years) treated in 3 different pediatric centers from 2004 to 2009. In 3 cases HS was associated with infections (EBV, CMV, Bacillus Calmette Guerin - BCG), in 1 child with non-Hodgkin anaplastic large cell lymphoma (ALCL), in 1 patients probably with side effect of antiepileptic drug. In 2 cases cause of HS remained unknown. Fever, hepatomegaly, pan- or bicytopenia and hyperferritinemia were present in all children. In addition, splenomegaly was noted in 6 cases, hemophagocytosis in 6 children, impaired function or decreased number of NK cells in 4 cases, hypofibrino-genemia in 5 and hypotriglyceridemia in 4 patients. Among other symptoms and signs we observed: lymphadenopathy, hepatic failure, oedema, rash, neurological symptoms, increased level of LDH and inflammatory markers. In one child acute pancreatitis occurred. Among others, antibiotics, antiviral and immunosuppressive drugs were used in therapy. HLH-2004 protocol was applied in 4 cases. Patient with ALCL was treated with chemotherapy and allogeneic stem cell transplantation. Four patients are alive, 2 died because of HS, child with ALCL died because of generalized infection in peritrans-plantation period. In case of prolonged fever, splenomegaly and cytopenia diagnosis of HS should be considered. Following tests are recommended: complete blood count, ferritin, triglycerides, fibrinogen, bone marrow aspiration and NK cell assessment. Patients should be also screened for infections and malignancies. Early diagnosis of HS and underlying condition is crucial to start lifesaving therapy.

Patients with Wiskott-Aldrich syndrome (WAS) are predisposed to malignancy and autoimmunity in addition to infections. We report a male child with WAS, who had presented with recurrent pneumonia, eczema, thrombocytopenia, autoimmune hemolytic anemia, and vasculitic skin lesions. Genetic analysis revealed a classical genotype WAS 155C>T; R41X. At 2 years of follow-up, he developed persistent headache and progressive hepatomegaly. Brain imaging showed a mass in the right frontal region, which on histopathology was shown to be high-grade non-Hodgkin lymphoma. Magnetic resonance cholangiopancreatography showed features of sclerosing cholangitis. This report extends the clinical spectrum and highlights unusual manifestations of sclerosing cholangitis and intracranial lymphoma in a patient with WAS.

BACKGROUND Extranodal natural killer/T-cell lymphoma, nasal type (ENKTCL) is generally an aggressive and rare non-Hodgkin lymphoma. It is most common in East Asians, Native Americans, and South Americans, but is rarely reported in blacks. CASE REPORT A 55-year-old African American male born in Grenada presented with a left nostril mass with facial swelling and biopsy subsequently confirmed a diagnosis of extranodal NK/T-cell lymphoma, nasal type (ENKTCL). Immunochemistry was positive for CD2, cytoplasmic CD3, CD7, CD 43, CD 56, granzyme B, and TIA-1. In situ hybridization was positive for Epstein-Barr virus encoded ribonucleic acid (EBERs). Bone marrow aspiration did not show lymphoma involvement. The patient had progressive neutropenia upon presentation, with further investigations showing hepatomegaly, hyperferritinemia, and hemophagocytosis in the bone marrow. We reached a diagnosis of hemophagocytic syndrome. He was treated with a high-dose combination chemotherapy and radiation therapy; the neutropenia improved significantly with steroids as treatment for immune activation in the setting of hemophagocytic syndrome. CONCLUSIONS To the best of our knowledge, this is the only second report of extranodal NK/T-cell lymphoma, nasal type in a black patient, and it raises the awareness of early recognition of rare manifestations of NK/T-cell lymphoma such as hemophagocytic syndrome.

Ataxia telangiectasia (A-T) is a neurodegenerative autosomal recessive disorder with the main characteristics of progressive cerebellar degeneration, sensitivity to ionizing radiation, immunodeficiency, telangiectasia, premature aging, recurrent sinopulmonary infections, and increased risk of malignancy, especially of lymphoid origin. Ataxia Telangiectasia Mutated gene, ATM, as a causative gene for the A-T disorder, encodes the ATM protein, which plays an important role in the activation of cell-cycle checkpoints and initiation of DNA repair in response to DNA damage. Targeted next-generation sequencing (NGS) was performed on an Iranian 5-year-old boy presented with truncal and limb ataxia, telangiectasia of the eye, Hodgkin lymphoma, hyper pigmentation, total alopecia, hepatomegaly, and dysarthria. Sanger sequencing was used to confirm the candidate pathogenic variants. Computational docking was done using the HEX software to examine how this change affects the interactions of ATM with the upstream and downstream proteins. Three different variants were identified comprising two homozygous SNPs and one novel homozygous frameshift variant (c.80468047delTA, p.Thr2682ThrfsX5), which creates a stop codon in exon 57 leaving the protein truncated at its C-terminal portion. Therefore, the activation and phosphorylation of target proteins are lost. Moreover, the HEX software confirmed that the mutated protein lost its interaction with upstream and downstream proteins. The variant was classified as pathogenic based on the American College of Medical Genetics and Genomics guideline. This study expands the spectrum of ATM pathogenic variants in Iran and demonstrates the utility of targeted NGS in genetic diagnostics.
