Extramedullary relapses of acute lymphoblastic leukemia (ALL) are rare and usually localized in the central nervous system. We describe such an uncommon case of extramedullary relapse of ALL in the breast of a 44 year old female. The patient, who had been diagnosed with precursor B cell, Philadelphia positive (Ph+) acute lymphoblastic leukemia (ALL) 5 years before and had been in complete molecular remission for the last 19 months, was admitted to the hospital for investigation of a hard, non-tender lump in her right breast. Mammography detected a dense, ill-defined mass, whereas on grey-scale and power Doppler sonography, the appearance of the lesion was consistent with malignancy. Histopathologic and immunohistochemical examination of the specimen demonstrated a similar immunophenotype (CD20+, CD10+, Tdt+, CD3-) as this of the onset ALL cell population in the bone marrow.

Current intensive treatment of pediatric T-cell acute lymphoblastic leukemia (T-ALL) has substantial side-effects, highlighting a need for novel biomarkers to improve risk stratification. Canonical biomarkers such as genetics and immunophenotype are largely not used in pediatric T-ALL stratification. This study aimed to validate the prognostic relevance of DNA methylation CpG island methylator phenotype (CIMP) risk stratification in two pediatric T-ALL patient cohorts: the Nordic NOPHO ALL2008 T-ALL study cohort (n=192) and the Dutch DCOG ALL-10/ALL-11 validation cohorts (n=156).

In this study, we determined the frequency of secondary lesions in 28 iAMP21 BCP-ALL patient samples and investigated cellular sensitivity for candidate-targeted drugs. iAMP21 was enriched in aberrations (10.

Historically, adolescents and young adults diagnosed with acute lymphoblastic leukemia (ALL) have faced lower survival rates compared to children with the same illness. Bullous pemphigoid (BP), a rare autoimmune skin disorder, poses unique challenges when occurring alongside hematologic malignancies. A 23-year-old male with ALL-L1 diagnosis who developed bullous pemphigoid in this report.

Adult T-cell leukemia/lymphoma (ATLL) is a type of blood cancer related to human T-cell lymphotropic virus type 1 (HTLV-1). The principal aim of this study was to investigate cellular processes related to innate immune response, intracellular protein transport, and translational initiation regulation in individuals afflicted with ATLL and Acute lymphoblastic leukemia (ALL). Whole blood samples and peripheral blood mononuclear cells were collected from 10 viral ATLL patients and 10 ALL subjects.

T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive hematological disease originating from the malignant transformation of T-cell progenitors, caused by the accumulation of genetic aberrations. One-fifth of T-ALL patients are characterized by ectopic expression of the homeobox transcription factor TLX3. However, the role of TLX3 in T-ALL remains elusive, partly due to the lack of suitable study models.
