Radiation-induced brain tumors are suggested to be the late complication of acute lymphoblastic leukemia (ALL) treatment. High-grade gliomas, meningiomas, and sarcomas are the most frequent neoplasms. Secondary anaplastic oligodendrogliomas are exceedingly rare. Five cases of pure anaplastic oligodendroglioma have been reported in the literature, and only 1 case was in ...

Progressive multifocal leukoencephalopathy (PML) is a demyelinating disease of the central nervous system caused by the John Cunningham (JC) virus, a DNA papovavirus. It is usually associated with conditions causing profound immunodeficiency, classically seen in patients with HIV/AIDS. Since its first description in 1958, PML has also been associated with ...

Entire ABL1 gene deletion without BCR/ABL1 rearrangement is a rare phenomenon, with only four cases previously reported. Here we describe a fifth case of ABL1 deletion without BCR/ABL1 rearrangement in an adolescent patient with precursor B-cell lymphoblastic leukemia (B-ALL) and review the relevant literature. It is not clear how ABL1 ...

Myeloid sarcoma (MS, previously named granulocytic sarcoma or chloroma) is a rare extramedullary tumour of immature myeloid cells. It can be present before, concurrently with, or after the diagnosis of acute myeloid leukemia. MS is extremely uncommon in acute promyelocytic leukemia (APL). In the case described here, MS was the ...

Leukemia cutis is an infiltration of malignant neoplastic leukocytes or their precursors into the epidermis, dermis, or subcutis. These neoplastic cells are derived from abnormal leukocytes in the bone marrow where maturation aberrations occur. Acute myelogenous leukemia (AML) is the second most common cause of leukemia cutis and the most ...

Reciprocal t(16;21)(p11;q22) is a rare chromosomal abnormality in acute myeloid leukemia (AML). The chimeric transcript FUS-ERG formed by this translocation which causes the replacement of RNA-binding domain of FUS (alias TLS) with the DNA-binding domain of ERG, and this event is thought to be responsible for leukemogenesis. Here we report ...

Rhabdomyosarcoma (RMS) is the most common soft-tissue tumor in childhood, but is extremely rare in elderly. We present a rare case of cardiac RMS, which developed 1 year after the diagnosis and management of acute lymphoblastic leukemia in a 68-year-old female. The occurrence of such phenomena is intriguing, especially in ...

Rearrangements involving chromosome region at 12p13 are common abnormalities in hematological malignancies, including myeloid and lymphoid types. ETV6 gene is usually involved in the 12p13 region. ETV6 rearrangements are more often observed in acute lymphoblastic leukemia than in acute myeloid leukemia (AML), where ETV6 gene deletions are more common than ...

Benzene exposure is well demonstrated as a cause of acute myelogenous leukemia, but not of chronic myelogenous leukemia. Previous literature reviews based on case series and cohort studies have not shown an association. We have now conducted a literature search for case-control studies that examine the association between benzene exposure ...

Fusariumspp are rare but important opportunistic pathogens in immunocompromised patients. Disseminated fusarial infections occur mostly in patients with hematologic malignancies with myelosuppressive chemotherapy or in patients with severe immunodeficiency. Although more frequent than Aspergillus fungemia, Fusarium fungemia remains a rare event. We describe the case of a female patient with ...

Therapy-related acute lymphoblastic leukemia (t-ALL) with t(9;22)(q34;q11.2) is rarely reported as a secondary malignant neoplasm. To our knowledge, only 10 Ph+ t-ALL cases have been reported in the literature. However, 8/10 cases were not reported individually but constituted parts of larger studies reporting cytogenetic abnormalities in secondary leukemia. Snyder et ...

Hypocellular variants of acute myeloid leukemia are very rare and almost always occur in old aged patients. In contrast, hypocellular acute lymphoblastic leukemia usually occurs in children. We report two Indian patients with hypocellular acute myeloid leukemia, a 32-year-old woman and a 13-year-old boy. Interestingly, one of the patients also ...

Opportunistic infections account for the majority of central nervous system lesions in adult immunosuppressed patients. In this setting, toxoplasmosis typically manifests as multiple abscesses readily seen on routine neuroimaging studies. Asymptomatic, widely disseminated Toxoplasma cysts without parenchymal reaction are also recognized. In contrast, widespread parasites in the brain parenchyma with ...

Newer biological treatment strategies have been developed in the last decade with some promising outcomes. Their safety, however, has been questioned lately with multiple reports of increased risk for malignancies and infectious complications. These reports render their use suboptimal. We report a 44-year-old woman receiving adalimumab (Humira) for advanced juvenile ...

We report the case of a 10-month-old girl who presented with a spontaneous ulcer on the left buttock which failed to heal despite antibiotic therapy. Histology showed changes consistent with pyoderma gangrenosum and the ulcer resolved rapidly with super-potent topical steroids under occlusion. Blood tests revealed a persistent neutropenia. Immunoglobulin ...

We report 2 cases of Geotrichum capitatum infection in leukemia patients for which Aspergillus galactomannan (GM) assay was positive. The diagnostic options of G. capitatum infections in hematologic patients were reviewed. Although the pathogen was isolated from blood in 77% of cases, diagnostic difficulties remain and GM assay may have ...

Flow cytometry is the preferred method of diagnosing and immunophenotyping acute lymphoblastic leukemia (ALL). However, there are situations in which immunohistochemical staining (IH) of bone marrow trephine biopsy specimens can be used to provide immunophenotypic information. To evaluate the use of IH and to confirm its value in diagnosing and ...

Acute myeloid leukemias (AMLs) with monocytic differentiation with or without recurring cytogenetic abnormalities have prognostic significance. Therefore, it is important to recognize such cases. Monocytic differentiation is identified by morphology and confirmed by cytochemical stains or flow cytometry. However, the materials for such analyses are not always available (air-dried aspirate ...

We report four cases of leukemia (three chronic myeloid and one T-cell acute lymphoblastic) presenting with priapism in children 9- to 13-year old. All of them presented with hyperleukocytosis, and three had anemia plus thrombocytosis. All patients underwent chemotherapy and two had leukopheresis. In all cases, priapism was managed conservatively. ...

Juvenile myelomonocytic leukemia (JMML) is a rare, aggressive, clonal hematopoietic disorder of childhood with features of both myelodysplasia (thrombocytopenia, anemia) and myeloproliferation (leukocytosis, monocytosis). In most cases there is marrow hypercellularity, splenomegaly, and extramedullary involvement. In 1997 an international consensus on terminology was reached and guidelines/criteria for diagnosis were proposed. ...

Among 23 cases of myeloproliferative neoplasms (MPNs) with an associated del(5q) seen at our institution, 14 (61%) fulfilled diagnostic criteria for primary myelofibrosis (PMF). Other diagnoses included polycythemia vera (PV; n=2), essential thrombocythemia (ET; n=1), post-ET myelofibrosis (n=1), systemic mastocytosis (SM; n=1), and MPN, unclassifiable (n=4). Compared to their del(5q)-negative ...

Although xanthogranulomatosis (XG), defined as multiple xanthogranulomas occurring simultaneously, was originally described in infants and children, a number of adult cases have been reported. Adult XG, which generally presents in the absence of hyperlipidemia, has many similarities to the childhood variant. Among the similarities are reports of the simultaneous development ...
