    Departament de Patologia i Terapèutica Experimental, Facultat de Medicina i Ciències de la Salut, IDIBELL, Universitat de Barcelona, L'Hospitalet de Llobregat, Barcelona, Spain.
    The cornification of keratinocytes on the surface of skin and oral epithelia is associated with the degradation of nuclear DNA. The endonuclease DNase1L2 and the exonuclease Trex2 are expressed specifically in cornifying keratinocytes. Deletion of DNase1L2 causes retention of nuclear DNA in the tongue epithelium but not in the skin. Read More

    Contrasting effects of an Mdm2 functional polymorphism on tumor phenotypes.
    Oncogene 2017 Sep 18. Epub 2017 Sep 18.
    Department of Genetics, The University of Texas MD Anderson Cancer Center, Houston, TX, USA.
    MDM2, an E3 ubiquitin ligase, is a potent inhibitor of the p53 tumor suppressor and is elevated in many human cancers that retain wild-type p53. MDM2 SNP309G is a functional polymorphism that results in elevated levels of MDM2 (due to enhanced SP1 binding to the MDM2 promoter) thus decreasing p53 activity. Mdm2(SNP309G/G) mice are more prone to spontaneous tumor formation than Mdm2(SNP309T/T) mice, providing direct evidence for the impact of this SNP in tumor development. Read More

    Department I of Internal Medicine and Center of Integrated Oncology Cologne-Bonn, German CLL Study Group, University Hospital of Cologne, Cologne, Germany.
    Background: The combined use of genetic markers and detectable minimal residual disease identifies patients with chronic lymphocytic leukaemia with poor outcome after first-line chemoimmunotherapy. We aimed to assess lenalidomide maintenance therapy in these high-risk patients.

    Methods: In this randomised, double-blind, phase 3 study (CLLM1; CLL Maintenance 1 of the German CLL Study Group), patients older than 18 years and diagnosed with immunophenotypically confirmed chronic lymphocytic leukaemia with active disease, who responded to chemoimmunotherapy 2-5 months after completion of first-line therapy and who were assessed as having a high risk for an early progression with at least a partial response after four or more cycles of first-line chemoimmunotherapy, were eligible if they had high minimal residual disease levels or intermediate levels combined with an unmutated IGHV gene status or TP53 alterations.

    Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare aggressive hematologic malignancy characterized by frequent skin involvement that most commonly affects older patients. BPDCN is known to have a poor prognosis. Our objective was to assess if outcome and disease prognosis were independently influenced by age when evaluated with clinical presentation, sex, and treatment regimens. Read More

    A Review of 7 Cases of Laparoscopic Cholecystectomy for Pediatric Cholecystolithiasis.
    J UOEH 2017 ;39(3):223-227
    Department of Surgery 1, School of Medicine, University of Occupational and Environmental Health, Japan.
    Pediatric cholecystolithiasis is a relatively rare disease, but it is recently increasing in Japan. Laparoscopic cholecystectomy (LC) is a standard procedure for cholecystolithiasis not only in adults but also in children, and we are aggressively introducing single-incision laparoscopic cholecystectomy (SILC) at our hospital. We reviewed the patient characteristics, operation procedures and outcomes of 7 children (15 years old and under) with cholecystolithiasis who underwent LC in our hospital between August 1995 and December 2015.

    Professor, Department of ENT, Maulana Azad Medical College, New Delhi, India.
    Myeloid sarcoma is an extramedullary manifestation of Acute Myeloid Leukaemia and sometimes is the only indicator of the disease. The incidence varies between 3-9.1% of acute leukaemia cases. Read More

    Chronic myelomonocytic leukemia masquerading as cutaneous indeterminate dendritic cell tumor: Expanding the spectrum of skin lesions in chronic myelomonocytic leukemia.
    J Cutan Pathol 2017 Sep 8. Epub 2017 Sep 8.
    Department of Pathology, The University of Texas MD Anderson Cancer Center, Houston, Texas.
    Chronic myelomonocytic leukemia (CMML) is a hematopoietic stem cell neoplasm exhibiting both myelodysplastic and myeloproliferative features. Cutaneous involvement by CMML is critical to recognize as it typically is a harbinger of disease progression and an increased incidence of transformation to acute myeloid leukemia. Cutaneous lesions of CMML exhibit heterogeneous histopathologic features that can be challenging to recognize as CMML. Read More

    Successful 5-azacytidine treatment of myeloid sarcoma and leukemia cutis associated with myelodysplastic syndrome: A case report and literature review.

    aDepartment of Hematology bDepartment of Transfusion Medicine and Regenerative Medicine, Niigata University Medical and Dental Hospital cDepartment of Pathophysiology, Faculty of Pharmaceutical Sciences, Niigata University of Pharmacy and Applied Life Sciences, Niigata, Japan.
    Rationale: Myeloid sarcoma (MS) and leukemia cutis (LC) are extramedullary tumors comprising myeloid blasts. They can occur de novo or concurrently with hematological disorders, usually acute myeloid leukemia (AML). AML chemotherapy is generally the initial therapy for MS and LC, and hematopoietic stem cell transplantation (HSCT) can be considered as additional therapy. Read More

    Severe Mucha-Habermann-Like Ulceronecrotic Skin Disease in T-Cell Acute Lymphoblastic Leukemia Responsive to Basiliximab and Stem Cell Transplant.
    Pediatr Dermatol 2017 Sep;34(5):e265-e270
    Division of Oncology, Children's Hospital of Philadelphia, Philadelphia, Pennsylvania.
    A 5-year-old girl with T-cell acute lymphoblastic leukemia (T-ALL) developed a progressive eruption of crusted papules and ulcerative plaques involving 80% of her body surface area with histopathology consistent with febrile ulceronecrotic Mucha-Habermann disease (FUMHD), although multiple specimens also contained clonal leukemic cells. Her skin disease was refractory to many classic treatments for FUMHD, including methotrexate, and became so severe that concern about superinfection prevented intensification of chemotherapy for her malignancy. The addition of basiliximab promoted gradual improvement of the skin, allowing for chemotherapy intensification and subsequent bone marrow transplantation, after which the eruption resolved completely.

    Livedoid eruption in a patient affected by T-γδ large granular lymphocyte leukaemia.
    BMJ Case Rep 2017 Sep 7;2017. Epub 2017 Sep 7.
    Unit of Dermatology, University of Padua, Padova, Italy.
    Livedo is an ischaemic dermopathy characterised by a reddish-blue to violaceous mottling of the skin with a net-like reticular appearance. Livedo has been described in association with several medical conditions including lymphoproliferative disorders. Here, we describe the case of a 60-year-old woman who was presented with asymptomatic and persistent livedoid eruption on her trunk, lower and upper extremities as manifestation of an indolent form of T-γδ large granular lymphocyte leukaemia.
