Hemophagocytic syndrome (HPS) is a rare clinicopathological disorder characterized by systemic proliferation of phagocytizing histiocytes associated with fever, cytopenias, lymphadenopathy, hepatosplenomegaly, and disseminated intravascular coagulopathy. We present the association of hemophagocytic syndrome associated with inappropriate secretion of antidiuretic hormone (SIADH) in two cases of hematological malignancies; anaplastic large cell lymphoma (ALCL) and acute myeloblastic leukemia (AML M4) In the patient with lymphoma, the diagnosis of lymphoma, HPS and SIADH were concurrent. In the patient with AML, HPS and SIADH were observed while the patient was in hematological remission. Thus it seems that patients with HPS may also carry a risk for the development of SIADH; the relationship with HPS and SIADH should be further investigated.

There has not been a reported series of children with therapy-induced myelodysplastic syndrome/acute myeloid leukemia (tMDS/tAML) who were treated systematically. This paper describes 24 children with tMDS/tAML who were assigned randomly to standard- or intensive-timing induction on protocol CCG 2891. Presenting features and outcomes of those children were compared with those of 960 patients with de novo MDS (62 patients) or AML (898 patients). Children with tMDS/tAML were older at presentation (P =.015), had lower white blood cell counts (P =.01), and were more likely to have MDS (21% vs 7%) (P =.02) and trisomy 8 (P =.06). Fewer had hepatomegaly (P =.02), splenomegaly (P =.03), hepatosplenomegaly (P =.02), or classic AML translocations [t(8;21), t(15;17), 16q22; P =.02]. They had a poorer induction rate (50% vs 72%, P =.016), overall survival (26% vs 47% at 3 years, P =.007), and event-free survival (21% vs 39% at 3 years, P =.023). Disease-free survival after achieving remission was similar (45% vs 53%, P =.868). Children with tMDS/tAML who received intensive-timing induction had better outcomes than those who received standard-timing induction (overall survival 32% vs 0%, P =.54). In this study, the latency period to development of tMDS/tAML was the same for presumed alkylator-induced as for topoisomerase-induced myeloid leukemia. The findings of this study confirm that most children with tMDS/tAML have disease resistant to current therapies. Standard-timing induction appears less effective for this population.

A 77-year-old man was referred to our hospital because of elevated LDH and leukoblastosis in the peripheral blood in June 2002. Physical examination revealed neither hepatosplenomegaly nor superficial lymphadenopathy. A bone marrow film showed dysmegakaryocytopoiesis with many micromegakaryocytes and MPO-positive blasts appearing in 20-30% of NCC. A diagnosis of MDS (RAEB-t) was made. Blastic cells were positive for CD13, 33, 34 and HLA-DR. Karyotypic analysis at diagnosis revealed 46XY, inv(3) (q21q26), t(9;22) (q34; q11) and minor-BCR/ABL chimeric m-RNA was detected by RT-PCR. Mild chemotherapy (low dose Ara-C etc) was given but the disease progressed to the AML stage with thrombocytosis in August. In September imatinib was given because of Ph positivity, but the effect was transient. In October massive leukocytosis with myeloblastosis was uncontrollable. In December 2002 the patient died of pneumonia, after a total course of 7.5 months. This rare case with Ph chromosome and 3q21q26 syndrome showed a poor prognosis as previously reported.

A 40 year old man presented with abdominal pain, jaundice, weight loss, and hepatosplenomegaly. Liver function tests revealed cholestatic jaundice and a computed tomography scan showed an enlarged liver, with a normal biliary tree. Liver biopsy showed diffuse infiltration by neutrophils, monocytoid cells, and blasts. Peripheral blood film and bone marrow were consistent with acute myeloid leukaemia. After treatment with chemotherapy using an acute myeloid leukaemia protocol (UK Medical Research Council AML-12), there was complete resolution of jaundice and the patient went into complete molecular remission.

Chronic eosinophilic leukemia is a rare entity, characterized by eosinophilia of >1.5 x 10(9)/L, persisting for >6 months after exclusion of other reactive and neoplastic causes of eosinophilia, and occurring in association with a clonal cytogenetic abnormality. Various chromosomal abnormalities have been associated with chronic eosinophilic leukemia. Partial deletion of the long arm of chromosome 16 is a cytogenetic abnormality first reported 20 years ago in patients with acute myeloid leukemia associated with bone marrow eosinophilia (AML-M4Eo). We report a case of a 45-year-old African-American male with hepatitis C and sustained peripheral blood eosinophilia who presented with gross hematuria, dyspnea on exertion, chills, decreased appetite and weight loss of 40 pounds associated with hepatosplenomegaly and lymphadenopathy. Bone marrow biopsy showed clonal cytogenetic abnormality consisting of deletion of the long arm of chromosome 16 (16q22). Philadelphia chromosome t (9;22) and polymerase chain reaction (PCR) analysis for C-kit and platelet-derived growth factor receptor-alpha (PDGFRA) mutations were negative. The patient was treated with imatinib at 400 mg/d with improvement of symptoms, reduction of lymphadenopathy and normalization of the eosinophil count. To our knowledge, this is the first case report of isolated del (16) (q22), a cytogenetic abnormality associated with AML-M4Eo, occurring in chronic eosinophilic leukemia. Whether this cytogenetic abnormality might represent a prodromal phase of AML-M4Eo is not known. In addition, the role of hepatitis C in inducing clonal proliferation of eosinophils is unclear.

Trisomy 10 as the sole cytogenetic abnormality in AML is rare, with an incidence rate of < 0.5%. It tends to affect the elderly and is extremely rare in pediatric patients. We describe a case of an 8-month-old Caucasian baby who presented with prominence of left eye and fever without lymphadenopathy or hepatosplenomegaly. Bone survey showed diffuse periosteal reaction in the femur, pelvis, maxillary and orbital bones (with fracture). CBC revealed normal white blood cell count with increased blasts, mild anemia and moderate thrombocytopenia. Bone marrow biopsy showed increased myeloblasts with bilineage dysplasia and 3-4+ reticulin fibrosis. Flow cytometry revealed blasts positive for CD34, CD33, and MPO and negative for CD7, CD13, and HLA-DR. Trisomy 10 was demonstrated by chromosome analysis and fluorescence in-situ hybridization. The patient received induction chemotherapy and achieved complete clinical and hematologic remission at day 28. However, he relapsed after three cycles of chemotherapy. Compared to the two other reported pediatric cases, our patient has some unique features such as much younger age and additional findings such as bilineage dysplasia and bone marrow fibrosis. Both reported cases and our case were classified as AML-M2 indicating that this may be a common subtype in pediatric patients. Bone involvement was present in our patient and one other case and both had similar immunophenotype (CD33+, CD7-). These findings suggest that isolated trisomy 10 may be associated with distinct clinicopathologic features in pediatric AML. Studies on additional patients are needed to establish this association.

The translocation (8;21)(q22;q22) is frequently associated with M2 subtype of AML. The authors herein present a case of AML-M2 in a nine-year-old boy without hepatosplenomegaly, lymphadenopathy or any bleeding diathesis. Bone marrow examination revealed high number of eosinophilic precursors (60%) among the total nucleated bone marrow cells. Cytogenetic study with G- banding method showed 46, XY, t (8;21)(q22;q22). The morphological abnormalities in eosinophils observed in AML suggested that eosinophils may be a part of leukemic process.

Osteopetrosis is a rare disease characterised by an increase in bone mass, skeletal malformations and bone marrow failure due to defective bone resorption. We report a 3-month-old male child presented with chest infections, failure to thrive and hepatosplenomegaly and diagnosed with osteopetrosis associated with acute myeloid leukaemia M3 type (AML-M3). The patient died on day 7 of admission due to respiratory failure. To our knowledge, this is the first case where both osteopetrosis and AML is diagnosed in a patient.

An infant presented with fever and purulent discharge from the left ear, proptosis of the right eye, and hepatosplenomegaly. She was diagnosed with acute monoblastic leukemia on morphological and flowcytometric analysis of the bone marrow. Karyotyping showed a jumping translocation (JT) involving the long arm of chromosome 1 as the sole cytogenetic abnormality in 29 metaphases. The patient died within 2 months of diagnosis. The presence of JT in a de novo infant AML as a sole cytogenetic abnormality indicates its possible role in leukemogenesis unlike previous reports that have implicated its role in tumor progression only.

Hemophagocytic lymphohistiocytosis (HLH), also known as hemophagocytic syndrome, is an aggressive hyperinflammatory condition characterized by prolonged fever, cytopenias and hepatosplenomegaly, as well as hemophagocytosis by activated, morphologically benign macrophages. HLH may be characterized into two forms, familial and secondary HLH. Familial HLH usually manifests in children with genetic abnormalities associated with the cytotoxic function of NK and T cells, whereas secondary HLH usually occurs in older patients in combination with an associated condition, such as infection or malignancy, without an identifiable genetic abnormality. Malignancy-associated hemophagocytic lymphohistiocytosis is mostly accompanied by lymphoid neoplasms. The present study reports a rare case of this syndrome in combination with acute myeloblastic leukemia (AML-M2), in a patient with clonal karyotypic abnormalities. The patient was successfully treated with chemotherapy comprising daunorubicin (40 mg/m² i.v., days 1-3) and cytosine arabinoside (100 mg/m², 1-h i.v. infusion, days 1-7). All clinical symptoms disappeared following chemotherapy.
