Juvenile myelomonocytic leukemia with t(3;5)(q25;q35), Auer rods and marked myelodysplasia

We present a 2-year-old boy with splenomegaly, leukocytosis, thrombocytopenia, anemia, and excess myeloblasts with easily seen Auer rods, and marked dysgranulopoiesis and dyserythropoiesis. Conventional cytogenetic analysis showed a sole abnormality of t(3;5)(q25;q35). Microarray analysis showed a terminal 21 Mb region of copy-neutral loss of heterozygosity on 19q. Disease-related somatic NRAS mutation was detected. This case represents an unusual JMML with Auer rods and marked myelodysplasia. These unusual histopathologic features may be related to the t(3;5)(q25;q35). A t(3;5) with variable breakpoints has been reported in a small proportion of acute myeloid leukemias and myelodysplastic syndromes. To our knowledge, this is the first JMML case reported with this translocation.

Purpose of review Immunotherapy for the treatment of cancer has advanced at a tremendous pace over the last decade. In this review, we provide an overview of recent progress in immunotherapy for the treatment of leukemia, focusing on antibody–drug conjugates (ADC), bi-specific T-cell engagers (BiTE), and chimeric antigen receptor (CAR) T cells. Recent findings Ongoing clinical trials of CAR T cells directed against CD19 have produced complete remission rates as high as 93%, prompting global multicenter phase 2 trials and the first FDA approval of a CAR T-cell therapy. Insights into cytokine release syndrome, a t...

Salivary gland neoplasms are a morphologically heterogenous group of lesions that are often diagnostically challenging. In recent years, considerable progress in salivary gland taxonomy has been reached by the discovery of tumor type-specific fusion oncogenes generated by chromosome translocations. This review describes the clinicopathologic features of a selected group of salivary gland carcinomas with a focus on their distinctive genomic characteristics. Mammary analog secretory carcinoma is a recently described entity characterized by a t(12;15)(p13;q25) translocation resulting in an ETV6-NTRK3 fusion. Hyalinizing clear...

Langerhans cell histiocytosis (LCH) has a mostly favorable outcome, whereas Langerhans cell sarcoma (LCS) is an aggressive tumor. It is still unclear whether any specific molecular alterations could underlie the aggressive behavior of Langerhans cell proliferations. We used targeted next-generation sequencing and array-comparative genomic hybridization to profile 22 LCH samples from different patients together with 3 LCS samples corresponding to different relapses from the same patient. The third LCS relapse was a composite tumor including both B-cell chronic lymphocytic leukemia and LCS components. The 22 LCH samples were...

ETV6 gene abnormalities are well described in tumor pathology. Many fusion partners of ETV6 have been reported in a variety of epithelial, mesenchymal, and hematological malignancies. In salivary gland tumor pathology, however, the ETV6-NTRK3 translocation is specific for (mammary analog) secretory carcinoma, and has not been documented in any other salivary tumor type. The present study comprised a clinical, histologic, and molecular analysis of 10 cases of secretory carcinoma, with typical morphology and immunoprofile harboring a novel ETV6-RET translocation.

We report 3 adult cases with lymphoblasts showing a precursor B cell immunophenotype, and isolated MYC/IGH translocation. All 3 cases occurred in male patients with initial presentation of diffuse lymphadenopathy. Cases 1 and 2 had B-ALL with significantly increased lymphoblasts in peripheral blood and bone marrow. Case 3, a patient with human immunodeficiency virus infection, had the diagnosis of B-LBL made on a retroperitoneal lymph node biopsy and had no peripheral blood or bone marrow involvement. The leukemic and lymphoma cells in all 3 cases demonstrated Burkitt lymphoma-like morphology with deeply basophilic cytopla...

Purpose of review To provide an overview of the principles, safety and efficacy of adoptive cell therapy (ACT) in solid tumors particularly in gynecological cancers. Recent findings Efforts to target solid tumors using tumor-infiltrating lymphocytes and genetically modified T cells have shown promising efficacy in some patients. Two food and drug administration approvals for the treatment of leukemia are the first gene therapies available for cancer treatment in the United States. Summary Genetic engineering of antitumor immunity using T cells has the potential to target specific tumor-associated antigens and overc...

Conclusion: In children with AML, adenovirus infection was rare and typically not associated with severe disease, even without specific treatment. However, disseminated and fatal disease can occur in this population. Further investigations are needed to identify pediatric AML patients at particular risk for severe adenovirus infection and to determine optimal treatment approaches in these patients.

We present a 5-year-old girl, originally from Equatorial-Guinea, diagnosed with severe malaria with acute kidney injury, thrombocytopenia and acute acalculous cholecystitis. She was treated with intravenous quinine and clindamycin, plus cefotaxime and metronidazole with a full resolution without surgery.
