Abstract
Acute myelogenous leukemia (AML) develops as the consequence of a series of genetic changes in a hematopoietic precursor cell. Specific cytogenetic abnormalities have been identified by karyotype analysis in AML. One of the rare chromosomal abnormalities is a dicentric chromosome, which is defined as an aberrant chromosome having two centromeres. In the literature, a limited number of cases have been reported with dic(1;15) in myeloid disorders, but only one case has been reported with in acute megakaryoblastic leukemia. Herein, we report a case of acute myelogenous leukemia without maturation with a dic(1;15)(p11;p11), resulting in trisomy of the long arm of chromosome 1. To date, this is the second case of dic(1;15) in acute myelogenous leukemia and the first case in acute myeloblastic leukemia without maturation.

Abstract
Translocations involving chromosomes 1 and 15 are uncommon in hematologic malignancies. So far, only 42 cases have been reported with t(1;15) as a reciprocal or complex chromosomal abnormalities. We herein report the first case in the literature, to our knowledge, of a 44-year-old female with essential thrombocythemia and severe myelofibrosis who developed acute myeloid leukemia (AML-M4) with der(1;15)(q10;q10) after 13 years of treatment. In addition, we reviewed the literature for all up-to-date published cases with t(1;15).

Abstract
A rare karyotypic event, der(1;15)(q10;q10), which involves the whole long arms of chromosomes 1 and 15, has been reported in patients with various conditions, including acute myelogenous leukemia, myelodysplastic syndrome, polycythemia vera, and multiple myeloma. Only 27 cases of unbalanced der(1;15)(q10;q10) have been documented in the literature as single or complexed chromosomal abnormalities in hematological malignancies. Here, we describe two cases of acute lymphoblastic leukemia with der(1;15)(q10;q10), and review the previous reports. Although more case studies are needed, we suggest that der(1;15)(q10;q10) should be considered a nonrandom chromosomal abnormality in hematological malignancies including both lymphoid and myeloid neoplasms.

Abstract
Myelodysplasia syndrome (MDS) presenting as spontaneous gingival hemorrhage is described. Gingival hemorrhage is recognized as a symptom of MDS, a rare group of potentially fatal hematological disorders, but it has not previously been documented as a presenting sign. The diagnostic pitfalls are discussed with the case, and the need for careful interpretation of laboratory findings in conjunction with clinical signs is emphasized. Finally, the MDSs are defined, classified and discussed with respect to their relevance to the clinical periodontist, from a diagnostic, therapeutic, and management standpoint.

Abstract
Survival of 5q(-)patients is known to depend on patient age, diagnosis, and acquisition of additional chromosome aberrations. The possible importance of the deleted 5q bands is unknown; nor is it known if the same or different factors are of prognostic importance in 5q(-)MDS and 5q(-)AML. In order to obtain material of sufficient size to answer these and other questions the literature was searched for 5q(-)cases with data on survival. Only MDS and AML cases with interstitial deletions were included. The results confirmed the prognostic importance of the factors mentioned above, but produced the following new data: In MDS, but not in AML, loss of the band 5q12 is an independent adverse prognostic factor; female patients survive longer in MDS while in AML men are the longer survivors; del(5)(q13q31) was found to be associated with MDS, 5q(-)as the sole aberration, and a long survival; on the other hand many del(5)(q12q32) cases showed AML, presence of additional aberrations, and short survivals. On the basis of these results the following hypotheses are proposed: 1) the female preponderance in 5q(-)MDS is due to longer female survival, and not to increased female incidence, and 2) some 5q deletions have a high diagnostic specificity, affect the rate of development of additional chromosome aberrations and thus in fact are major prognostic factors.

Abstract
Cytogenetic analysis has proven to be a mandatory part of the diagnosis of myelodysplastic syndromes (MDS) as well as a major indicator for predicting clinical course and outcome. This review concentrates on the cytogenetic classifications, the incidence and types of chromosome defects and the prognostic significance of the karyotype in adult primary MDS. Two cytogenetic classifications are currently used: one is based on the karyotype complexity (normal, single, double or complex defects), the other on clonal status (all metaphases normal, abnormal or admixture of normal and abnormal clones). Chromosome abnormalities are of both numerical and structural types. Aside from the 5q-syndrome, no specific clinico-cytogenetic entity has been reported. However, several distinct clinical and cellular features have been identified that correlate with the presence of specific chromosome defects such as inv(3)/t(3;3), +6, t(5;12), del(17p) and del(20q). The presence of complex defects is associated with reduced survival and a high risk of leukemic transformation. Among single defects, specific abnormalities may define distinct prognostic groups. Patients with del(5q) as a sole chromosome defect and a refractory anemia without excess of blasts have a favourable prognosis. For patients with trisomy 8 or monosomy 7 there may be distinct types of clinical evolution. Most patients with the 3q21q26 syndrome have a short survival. The presence of two chromosome defects may constitute an independent cytogenetic entity probably associated with relative poor prognosis. Karyotypic evolution generally represents a poor risk factor. The combination of cytogenetics with clinical and hematological features has proven to provide for a better prediction of patients' survival, leukemic transformation and response to treatment. Several scoring systems have been developed. They have to be improved by the study of new patients according to strict clinical and cytogenetic criteria and by the addition of newly recognized prognostic indicators such as histopathological features and molecular genetic mutations.

Abstract
We report three cases of myeloid disorders with a dic(1;15)(p11;p11), resulting in trisomy of the long arm of chromosome 1. A review of the literature showed six cases, reported as t(1;15). We suggest that these cases have the same anomaly and should be reappraised as dic(1;15).

Abstract
The occurrence of an unusual karyotypic abnormality der(1;15)(q10;q10) is reported in three patients, one with acute megakaryoblastic leukemia and two with myelodysplastic syndrome. A literature review shows that this cytogenetic abnormality is a rare but nonrandom change in myeloid neoplasia/neoplasia.

Abstract
Cytogenetic and clinical data of 11 patients with de novo myelodysplastic syndromes and partial or total trisomy of the long arm of chromosome 1 are presented. In eight of these patients trisomy 1q was the sole karyotypic change and therefore can be classified as a primary chromosome anomaly. A remarkably young median age of 36.5 years was noticed in this patient group.

Abstract
Three cases of idiopathic myelofibrosis with partial trisomy of the long arm of chromosome 1 are described. Partial trisomy 1q was the only karyotypic change detectable in unstimulated peripheral blood cell cultures of one and bone-marrow cultures of two patients at diagnosis. The extra segment from chromosome 1 was located on different karyotype sites, i.e. 1qter, 1p34 and 6p22-23; 1q21-32 was the shortest overlapping region and the only trisomic segment in one of the three patients. These findings suggest that partial trisomy 1q is a primary chromosome aberration in myelofibrosis relevant in the pathogenesis of this hematologic disorder.

Abstract
Two male patients with myelodysplastic syndromes, one with refractory anemia with excess blasts (RAEB), the other with chronic myelomonocytic leukemia both had in their bone marrow and peripheral blood cells the same abnormal karyotype 46,X,-Y, + der (Y)t(Y;1)(q12;q21). This abnormality produced trisomy for the 1q21-1qter region of chromosome 1. In addition to the t(Y;1), the patient with RAEB had a del(20)(q11) abnormality in separate CFU-GM and BFUe progenitor cell populations. The t(Y;1) clone of this patient underwent chromosomal evolution with the acquisition of trisomies for chromosomes 2, 6, 8, and 9. Cytogenetic analysis of serial peripheral blood samples showed that the t(Y;1) clone and its derivatives gradually replaced that with the 20q- abnormality. Metaphase cells trisomic for chromosomes 2, 6, 8, and 9 were found predominantly in the CFU-GM population and only rarely in BFUe colonies, suggesting that chromosomal evolution was largely confined to the granulocytic lineage.

Abstract
Complete or partial trisomy of the long arm of chromosome #1 was observed in six patients with malignant disorders. Four patients suffered from hematologic diseases (two cases of refractory anemia with excess of blasts and one case each of acute myeloblastic leukemia and Burkitt lymphoma), and two had solid tumors (retinoblastoma and Ewing's sarcoma). In all cases the excess material included the distal part of chromosome #1. Such material was translocated to chromosomes #16 (three patients), #3, #9, and Y (one patient each), and this was accompanied by additional cytogenetic changes in five of the six patients. The present and other previously published observations support the hypothesis of the localization of genes responsible for malignant growth in the distal segments of chromosome #1.
