Somatic insertions/deletions in the calreticulin gene have recently been discovered to be causative alterations in myeloproliferative neoplasms. A combination of qualitative and quantitative allele-specific polymerase chain reaction, fragment-sizing, high resolution melting and Sanger-sequencing was applied for the detection of three driver mutations (in(More)
Invasive mycoses are pre-eminent causes of morbidity and mortality in the allogeneic stem cell transplant setting. In spite of novel diagnostic modalities, the timely and specific identification of invasive mycoses still remains challenging. We analyzed the case history of 97 consecutive patients receiving 103 allogeneic stem cell transplants between(More)
Mycosis fungoides (MF) is a common, indolent primary cutaneous T-cell lymphoma (CTCL), with rare, more aggressive variants, such as folliculotropic MF (FMF). A minority of the MF cases may undergo large cell transformation (T-MF) associated with poor prognosis. A selection of microRNAs (miRs) contribute to the pathogenesis and progression of classic MF, and(More)
Mutations of isocitrate dehydrogenase 1 and 2 (IDH1/2) are genetic alterations in acute myeloid leukemia (AML). The aim of our study was to investigate the frequency and prognostic effect of IDH1/2 mutations together followed by an individual analysis of each substitution in a Hungarian cohort consisting of 376 patients with AML. IDH1(mut) and IDH2(mut)(More)
The diagnosis, classification, and prognostication of patients with myelodysplastic syndromes (MDS) are usually based on clinical parameters, analysis of peripheral blood and bone marrow smears, and cytogenetic determinants. However, a thorough histologic and immunohistochemical examination of the bone marrow is often required for a final diagnosis and(More)
BACKGROUND Folliculotropic mycosis fungoides (FMF) represents a variant of MF characterized by hair follicle invasion of mature, CD4-positive small lymphoid cells with cerebriform nuclei. The disease displays resistance to standard treatment modalities and has an unfavourable course. OBJECTIVE Clinical analysis of 17 patients with FMF collected between(More)
BACKGROUND Prognostic risk stratification according to acquired or inherited genetic alterations has received increasing attention in acute myeloid leukemia in recent years. A germline Janus kinase 2 haplotype designated as the 46/1 haplotype has been reported to be associated with an inherited predisposition to myeloproliferative neoplasms, and also to(More)
Multicentric Castleman’s disease (MCD) is a sytemic disorder with flares of non-specific symptoms suggestive of a chronic inflammatory syndrome. It is typically accompanied by generalized lymphadenopathy and multiorgan involvement. Histologically, two main variants of Castleman’s disease exist, the hyalin vascular type and the plasma cell variant. Upon(More)
Splenic marginal zone lymphoma is a rare disease, accounting for 1% of all lymphomas. We reviewed our single center experience of 13 patients with splenic marginal zone lymphoma (SMZL). Based on the prognostic model developed by Intergruppo Italiano Linfomi, 31% (4/13) of our patients had good, 38% (5/13) had intermediate and 31% (4/13) had a poor(More)
