Systemic mastocytosis (SM) refers to a group of heterogeneous diseases that can be divided into indolent SM, for which prognosis is favorable, and malignant SM, which has a poor prognosis. While the diagnosis of SM is often a challenge since clinical and biological abnormalities are not specific, prognosis is even more difficult to predict. Thus, we aimed to highlight predictable factors in a cohort of 28 cases of SM. Among the 13 women and 15 men studied were 7 patients who had an aggressive form of SM that ultimately led to death in 3 of them. We found common characteristics among these seven patients. First, they were older when the first symptoms appeared and when the diagnosis was confirmed. Second, ascitis, lymphadenopathy, anemia, and thrombocytopenia were significantly more frequent, while cutaneous lesions and flush were less frequent. Moreover, general symptoms, gastrointestinal disorders, neutropenia, and coagulation abnormalities also seemed to characterize this group of patients. Understanding the factors that predict SM is essential in order to provide patients with the malignant form of the disease with specific treatments.

Kikuchi-Fujimoto disease, also known as histiocytic necrotising lymphadenitis, is a self-limiting condition of uncertain aetiology characterised by lymphadenopathy, pyrexia, and neutropenia. Some reported cases have been associated with systemic lupus erythematosus and there have been suggestions that Kikuchi's disease could represent a mild form of lupus but without definite evidence. We describe an unusual case of histiocytic necrotising lymphadenitis in an Asian woman who had recurrent episodes for five years before a diagnosis was made.

We describe a female with a history of autosomal recessive hyper-IgM (HIGM) syndrome along with a history of autoimmune hemolytic anemia and intermittent lymphadenopathy. She subsequently developed neutropenia, lymphocyostosis and mild thrombocytopenia. Flow cytometry of the peripheral blood revealed the presence of a marked predominance of cytotoxic T lymphocytes, shown to be clonal, with concomitant natural killer (NK) antigen expression. She responded to weekly methotrexate therapy.

Therapeutic options are limited and the prognosis is poor for patients with fludarabine-refractory B-cell chronic lymphocytic leukemia (CLL). Bortezomib induces apoptosis in vitro in CLL cells, both alone and in combination, including in cells resistant to fludarabine or other agents. The aim of the current randomized, open-label, Phase II study was to investigate the clinical activity of bortezomib in patients with fludarabine-refractory B-cell CLL. Twenty-two patients with histologically confirmed B-cell CLL were treated with bortezomib at doses of 1.0 mg/m2, 1.3 mg/m2, or 1.5 mg/m2 on Days 1, 4, 8, and 11 of a 21-day treatment cycle for a maximum of 9 cycles. None of 19 patients evaluable for response achieved complete remission or partial response; however, signs of biologic activity based on disease site responses (e.g., reduction in lymphocytosis, splenomegaly, and lymphadenopathy) were observed. In the 1.5 mg/m2 dose group, a higher proportion of patients had stable disease, and a lower proportion had progressive disease compared with the 2 lower-dose groups. Eleven patients, all in the 2 higher dose groups, experienced Grade 3/4 adverse events (AEs) (according to National Cancer Institute Common Toxicity Criteria [version 2.0]); 2 patients experienced Grade 4 neutropenia. Grade 3 hematologic AEs included anemia, neutropenia, thrombocytopenia, and hemolytic anemia; Grade 3 nervous system AEs included aphasia; peripheral neuropathy, not otherwise specified; and peripheral sensory neuropathy. Although no objective responses were achieved in patients with fludarabine-refractory B-cell CLL, single-agent bortezomib demonstrated biologic activity. In view of the evidence for its activity, further exploration of bortezomib in combination with other agents is warranted.

A 56 years adult male presented with fever for 3 weeks with neutropenia and cervical lymphadenopathy with left sided pneumonitis. Histopathology of lymphnode was consistent with Kikuchi's Necrotizing Lymphadenitis. Kikuchi's disease is usually a self- limiting illness characterized by pyrexia, neutropenia and cervical lymphadenopathy in young women of Asian decent. This often leads to the misdiagnosis of lymphoma or tuberculosis. The notable feature here is an older male presented with severe neutropenia and pneumonia with hypoplastic marrow.

A 42-year-old woman was diagnosed with myelodysplastic syndrome with fibrosis that developed bilaterally, cervical lymphadenopathy and cutaneous infiltration by trilineage extramedullary hematopoiesis after granulocyte colony-stimulating factor therapy because of severe neutropenia. Hepatosplenomegaly was not observed during her follow-up. Extramedullary hematopoiesis disappeared after growth factor therapy was stopped. Although the neutropenia was alleviated by growth factor administration, the appearance of an unusual involvement of extramedullary hematopoiesis should be kept in mind.

The Asian variant of intravascular large B-cell lymphoma (AIVL) is a rare aggressive lymphoma characterized by various clinical symptoms, hemophagocytic syndrome and predominant growth within vessels. We present a 73-year-old man with relapsed AIVL who had been treated with six courses of CHOP regimen. A half year later, he presented with high fever, sweat, dementia and hepatosplenomegaly without lymphadenopathy. A bone marrow biopsy showed prominent hemophagocytosis and immunological staining disclosed an augmented intrasinusal pattern of atypical large lymphocytes characteristic of the CD20+ and CD5+ phenotypes. As salvage therapy, CND-R (rituximab, cladribine, mitoxantrone, dexamethasone) was performed, and the clinical symptoms immediately and dramatically improved. Subsequently, CND-R therapy was repeated every 4 weeks. No serious adverse events were observed with the exception of grade 4 neutropenia and grade 3 thrombocytopenia. After completion of the fifth course, a bone marrow biopsy pathologically confirmed complete remission, leading to termination of this therapy. The patient has remained in remission for more than 15 months. CND-R therapy, which is effective for indolent lymphoma, may be one of the candidates in salvage therapy for relapsed AIVL.

Purpose was to describe the clinical, radiological and therapeutic features in primary liver lymphoma. We report the case of a 54-year-old patient, who is followed since the age of 20 years for neutropenia associated with mediastinal adenopathy. Systematical ultrasound find a mass of the left liver confirmed by Computed tomography (CT). Histological examination of laparoscopic liver biopsy specimens confirmed diffuse large-cell non-Hodgkin's lymphoma. The disease was confined to the liver without any evidence of extrahepatic involvement. The serology of Epstein Barr virus was highly positive. PET-scan show increased FDG uptake at the site of hepatic lesion and the mediastin. The patient received chemotherapy followed by radiation therapy of the left liver at the dose of 31 Gy. The patient was alive and free of disease 20 months after the diagnosis of primary liver lymphoma. The primary hepatic lymphoma is a rare malignancy, which classically affects 50-year-old patients with a male preponderance. The incidence is increased in immunosuppressed patients and some authors have suggested an association with hepatitis B or C infection, and with the Epstein Barr virus. The imaging studies including ultrasound, CT, magnetic resonance imaging (MRI) and now PET-scan help to establish the diagnosis and to the following. Treatment options are surgery, radiation, chemotherapy, or a combination.

Omenn syndrome is a severe combined immunodeficiency characterized by erythroderma, hepatosplenomegaly, lymphadenopathy and failure to thrive, with activated oligoclonal T lymphocytes and an absence of circulating B cells.A 3 day-old boy presented with a congenital erythroderma. Investigations revealed a marked neutropenia and lymphopenia and the absence of a thymus. Genetic studies showed RAG 1 mutations. He was successfully treated with an HLA identical bone marrow transplantation. Omenn syndrome is a rare severe combined immunodeficiency. Most cases are due to mutations in the RAG genes with autosomal recessive transmission. Our observation is original because of an incomplete clinical presentation. During the course of the disease, the child had no failure to thrive, no organomegaly and no recurrent infection. Immunodeficiency must be excluded in every case of neonatal erythroderma and an immunological assessment should be performed without delay.

A 37-year-old man was presented with incidental findings of neutropenia, atypical lymphocytosis, thrombocytopenia and deranged liver parenchymal enzymes. Four days later, he developed fever, sore throat and cervical lymphadenopathy, compatible with mononucleosis-like illness (MLI). Polymerase chain reaction (PCR) and viral culture of the nasopharyngeal swab showed human metapneumovirus (hMPV). There was a >/=4-fold rise in IgG against hMPV. This is the first case report illustrating the natural clinical course of hMPV-related MLI.
