Abstract
Acute Myeloid Leukaemia (AML) is a neoplasia characterised by rapid proliferation and an increased rate of relapses. The AML blasts display features of antigen-presenting cells (APC), and thus can directly modulate the anti-tumour T cell responses. The bone marrow of a group consisting of 30 newly diagnosed patients and four healthy donors (HD) was investigated for the expression of HLA-DR, several molecules involved in MHC-II antigen-presentation and MHC-II groove editing, like HLA-DM, CD74 and CLIP, as well as a set of immune checkpoint ligands, like ICOS-L, B7.2, PD-L2 and B7-H3. The patients were further characterised for their genetic anomalies and distributed to favourable, intermediate and adverse ELN risk categories. We were able to show that while 23% of our patients displayed a low level of HLA-DR surface expression, all patients displayed higher HLA-DM and CD74 expression compared to HD. However, a higher CLIP expression was noticed only in the HLA-DR low patients. The co-inhibitory PD-L2 and B7-H3 molecules were increased in the cases with normal HLA-DR expression; oppositely, the co-stimulatory ICOS-L and the dual function B7.2 were significantly increased in the cases with HLA-DR low expression. Furthermore, no favourable ELN risk cases were found within the HLA-DR low group. All in all, these data show that the AML with low versus normal HLA-DR expression display different profiles of MHC class II machinery molecules and B7 ligands, which are correlated with distinct ELN stratification. Furthermore, as our study included healthy individuals, it offers valuable information about the expression levels that should be considered as normal for these markers known to cause differences in peptide repertoires, reflected further in distinct T-cells polarisation pathways.

Abstract
Abstract
Background: Acute basophilic leukemia is a rare subtype of acute myeloid leukemia, as categorized by the 2008 World Health Organization classification of myeloid neoplasms. Acute basophilic leukemia diagnosis requires thorough morphological, cytochemical, immunophenotypic, molecular, and cytogenetic studies and exclusion of other hematological neoplasms associating basophilia. The disease course is defined by histamine driven, occasionally life-threatening respiratory, cardiovascular, cutaneous or digestive complications, as well as primary refractoriness to standard therapy. Clinical presentation: We herein report a case of a 63-year-old asthmatic female patient diagnosed with acute basophilic leukemia, associated with previously unpublished cytogenetic features and FLT-3 ITD mutation, pulmonary leukostasis and spontaneous pulmonary capillary leak syndrome, which worsened immediately following chemotherapy initiation. Respiratory complications were successfully managed, but recrudesced upon emergence of refractory disease and were ultimately fatal. We highlight the likelihood of pulmonary complications induced by basophil degranulation and tumor lysis in hypercellular acute basophilic leukemia and the potential benefit of histamine receptor blockade in this setting.

Abstract
AbstractThe coexistence of t(9;22) and inv(16) has been described in a very limited number of cases of CML, de novo or therapy-related AML. We report a patient with CML who presented both inversion of chromosome 16 and Philadelphia chromosome and evolved towards the blast phase under treatment with Imatinib. Laboratory diagnosis and monitoring was made by flow cytometry, conventional cytogenetics and molecular genetics techniques. The inv(16), detected by karyotyping in the Philadelphia chromosome positive clone at the moment of the blast transformation, was retrospectively assessed by means of real-time PCR, and was proved to have been present since diagnosis. The bone marrow biopsy performed in the blast phase of CML confirmed the presence of blasts belonging to the myeloid lineage, with indications of monocytic differentiation, frequently associated with inv(16). Moreover, the case also associated a F359V tyrosine kinase domain mutation, resulting in intermediate resistance to Imatinib and Nilotinib, which imposed therapy-switch to Dasatinib. In our case the evolution was progressive, followed by death due to lack of response to tyrosine kinase inhibitors, 18 months after diagnosis. The coexistence of t(9;22) and inv(16) in CML seems to be associated with an aggressive clinical evolution and resistance to tyrosine kinase inhibitor therapy. Due to the very small number of cases described in literature, therapeutic decisions are still difficult for patients displaying these abnormalities

Abstract
HIV/AIDS is considered to be revealing of oncological diseases, of which most frequent are lymphomas. The main causes for this type of disease are non-adherence and non-compliance to antiretroviral therapy (ART). We are hereby presenting a clinical case of lymphoma in an HIV-infected adult, with non-adherence for 30 months. In such a case the interdisciplinary collaboration with the hematologist was essential for the patient's survival.

Abstract
Leishmaniasis is a parasitic infection caused by protozoans classified as Leishmania species. Romania is not considered an endemic country and there are only few reports of sporadic cases in the last 100 years. However, studies suggest that the disease is spreading north. We present the case of a 44 year old female that presented with asthenia, perspirations, vertigo, weight loss and menometrorhagias in small to medium quantity. Clinical exam revealed the presence of splenomegaly and her blood tests indicated she had pancitopenia; differential diagnosis included myeloproliferative or lymphoproliferative disorders, infections that evolve with spleen enlargement, autoimmune-related splenomegaly and hepatic--all tests were negative. She refused the bone marrow aspiration. Three months later, her condition worsened and the menometrorragias became more severe. Bone marrow aspiration revealed the presence of numerous intra and extracellular Leishmania spp. amastigotes. A detailed anamnesis showed that she had worked for six months in Italy as a care-giver nine months ago. She was transferred to Bucharest where she received optimal treatment. However, due to the continuous bleeding, the evolution was unfavourable. This is an alarm sign for physicians that should take into account the fact that, due to population migration and global warming, tropical infectious diseases are becoming more and more common. The signs and symptoms, as well as the treatment in leishmaniasis are reviewed, as well as a brief history of leishmaniasis in Romania.

Abstract
AIM Bone marrow stromal cells (BMSCs) have been found to support leukemic cell survival; however, the mechanisms responsible are far from being elucidated yet. The main aim of the current study is to identify particular cytokine/chemokine patterns of acute myeloid leukemia (AML) cells, and, on a longer term, to correlate them with the patient outcome and response to therapy. Therefore, the influence of BMSCs on in vitro modulation of cytokine secretion (IL-1beta, TNF-alpha, IL-10, IFN-gamma, IL-4, IL-5, and IL-2) by AML cells as well as the AML cells supportive capacity of BMSCs-derived soluble factors was investigated. MATERIAL AND METHODS With this purpose, we used an in vitro experimental model consisting in the evaluation of the effect of BMSC confluent layers-conditioning medium (BMSC-CM) on M4/5 AML cell cultures. RESULTS Our results show that BMSC-CM from both AML patients and healthy subjects conferred a substantial beneficial effect on AML cells throughout the culture (p=0.0002 and 0.0020 respectively at 24 hours and p=0,0013 and 0,0030 respectively at 72 hours), with a temporary increase in AML cell viability conferred by BM plasma from AML patients. Significant differences were observed with respect to IL1 b secretion which was upregulated in AML cell cultures both after 24 and 72 hours following the addition of AML-BMSC-CM, in contrast to control-BMSC-CM. CONCLUSION Our results suggest the contribution of BMSCs from AML patients to the generation of particular factors which may be key players involved in the in vivo maintenance of the malignant clone.

Abstract
We present a case of thyroidian cancer and chronic granulocytic leukemia simultaneously found in a 28 years old patient. Initial surgical management consisted in total thyroidectomy and removal of the lymph nodes; local recurrence after 6 months required excision of the tumoral block by radical neck dissection. Hematological disease was controlled with Hydroxiureea, associated, when needed, with Busulphan and Cytosar. The patient is in acceptable general condition and free of any local recurrence or apparent metastases 2.5 years after the diagnosis.

Abstract
Castleman's disease, also called angiofollicular hyperplasia was first described as a distinct entity by Castleman et al in 1956. Now there are described two forms, a localised and a multicentric one. All forms of disease share the same histopathological features with a highly characteristic angiofollicular lymphoid hyperplasia which is either hyalinovascular or plasmocytic. The clinical and biological signs are varied and heterogeneous. The disorder is of unknown origin, but interleukin 6 plays a central part in this disease. Despite the benignity of this "prelymphoma state", an aggressive course with poor prognosis occur usually in the multicentric form. We report a case of Castleman's disease, multicentric variant. This case provides the opportunity for discussing many aspects of this atypical lymphoproliferative disorder.
