    Erdheim-Chester Disease: Comprehensive Review of Molecular Profiling and Therapeutic Advances.
    Anticancer Res 2017 06;37(6):2777-2783
    Division of Hematology and Oncology, Department of Medicine, George Washington University Medical Center, Washington, DC, U.S.A.
    The revised 2016 World Health Organization classification introduced Erdheim-Chester disease (ECD) as a provisional entity within the histiocytic and dendritic cell neoplasms separate from the juvenile xanthogranuloma family based on distinct molecular features. However, evolving knowledge regarding the molecular and genetic aberrations in addition to common clinical features of ECD support the classification of ECD together with Langerhans cell histiocytosis (LCH). Accordingly, ECD can be thought of as an inflammatory myeloid clonal disorder based on the detection of various activating mutations along the mitogen activated protein kinase-extracellular signal regulated kinase (MAPK-ERK) pathway with most notable variant being a valine to a glutamic acid substitution at amino acid 600 in the B-rapidly accelerated fibrosarcoma protein (BRAFV600E).

    Neonatal glaucoma associated with juvenile xanthogranuloma: Case report.
    Arch Soc Esp Oftalmol 2017 May 15. Epub 2017 May 15.
    Servicio de Oftalmología, Hospital Sant Joan de Déu, Esplugues de Llobregat, Barcelona, España.
    Case Report: The case concerns a 22 day-old male child with juvenile xanthogranuloma (JXG), which manifested as a unilateral glaucoma and with fibrinous haemorrhagic exudate in the anterior chamber affecting the angle of the right eye. Despite a high level of suspicion, the definitive diagnosis was not possible until the infant reached the age of 10 months, after the appearance of the skin lesions typical of this condition and histopathological study of them.

    Conclusion: JXG is a rare disease, characterised by yellowish skin lesions on the trunk, neck, or head. Read More

    Activating MAPK1 (ERK2) mutation in an aggressive case of disseminated juvenile xanthogranuloma.
    Oncotarget 2017 04 29. Epub 2017 Apr 29.
    Texas Children's Cancer Center, Texas Children's Hospital, Houston, TX 77030.
    Juvenile xanthogranuloma (JXG) is a rare histiocytic disorder that is usually benign and self-limiting. We present a case of atypical, aggressive JXG harboring a novel mitogen-activated protein kinase (MAPK) pathway mutation in the MAPK1 gene, which encodes mitogen-activated protein kinase 1 or extracellular signal-regulated 2 (ERK2). Our analysis revealed that the mutation results in constitutive ERK activation that is resistant to BRAF or MEK inhibitors but susceptible to an ERK inhibitor. Read More

    Department of Pathology, Faculty of Medicine, Chulalongkorn University, Bangkok, Thailand; Chulolongkorn GenePRO Center, Research Affairs, Faculty of Medicine, Chulalongkorn University, Bangkok, Thailand. Electronic address:
    Juvenile xanthogranuloma (JXG) is a cutaneous form of non-Langerhans cell histiocytosis (LCH), primarily affecting children. The lesion is presumed to originate from either macrophages or dermal dendritic cells. JXG can rarely present as an isolated intracranial lesion and, in contrast to the dismal outcome of patients with systemic disease, cranial JXG has been shown to carry a more favorable prognosis.

    The clinical spectrum of xanthomatous lesions of the eyelids.
    Int J Dermatol 2017 May 13. Epub 2017 May 13.
    Pathology, Istanbul Medical Faculty, Istanbul University, Istanbul, Turkey.
    Yellowish papules, nodules, or plaques, namely "xanthomatous" lesions, may be seen on the eyelids in the course of various disorders. The prototype is "xanthelasma palpebrarum" (XP) that is localized only to the eyelids and may be associated with hyperlipidemia. On the other hand, different types of normolipemic disorders may also cause xanthomatous eyelid lesions. Read More

    Juvenile xanthogranuloma is a non-Langerhans cell lesion mostly limited to the skin but occasionally presenting in extracutaneous locations or associated with systemic conditions. Lesions need to be distinguished mainly from dermatofibroma, xanthoma, Langerhans cell histiocytosis, or reticulohistiocytoma. Herein, we present a hemosiderotic variant of juvenile xanthogranuloma in a 12-year-old girl, which we have not found described in literature. Read More

    Histiocytosis with mixed cell populations.
    J Cutan Pathol 2016 May 4;43(5):456-60. Epub 2016 Apr 4.
    Department of Pathology, Hospital Clínico Universitario, Valencia, Spain.
    Langerhans cell histiocytosis (LCH) and juvenile xanthogranuloma (JXG) are thought to originate from a common stem cell precursor, with divergent differentiation under different microenvironmental conditions. We describe an exceptional case of multiple cutaneous lesions in a 10-year-old boy, in which the coexistence of both LCH and JXG cell populations is found in every single lesion. The presence of Birbeck granules and CD207 (langerin) immunostaining in the LCH component would argue against the diagnosis of indeterminate cell histiocytosis (ICH). Read More

    Successful treatment with cladribine of Erdheim-Chester disease with orbital and central nervous system involvement developing after treatment of Langerhans cell histiocytosis.
    Vojnosanit Pregl 2016 Jan;73(1):83-7
    Introduction: Erdheim-Chester disease (ECD) is a rare, systemic form of non-Langerhans cell histiocytosis of the juvenile xanthogranuloma family with characteristic bilateral symmetrical long bone osteosclerosis, associated with xanthogranulomatous extra skeletal organ involvement. In ECD, central nervous system (CNS) and orbital lesions are frequent, and more than half of ECD pa tients carry the V600E mutation of the protooncogene BRAF. The synchronous or metachronous development of ECD and Langerhans cell histiocytosis (LCH) in the same patients is rare, and the possible connection between them is still obscure. Read More

    An Update on Neurofibromatosis Type 1: Not Just Café-au-Lait Spots and Freckling. Part II. Other Skin Manifestations Characteristic of NF1. NF1 and Cancer.
    Actas Dermosifiliogr 2016 Jul-Aug;107(6):465-73. Epub 2016 Mar 5.
    Servicio de Neurología, Hospital Infantil del Niño Jesús, Madrid, España.
    Neurofibromatosis type 1 (NF1) is the most common neurocutaneous syndrome and probably the one best known to dermatologists. Although the genetic locus of NF1 was identified on chromosome 17 in 1987, diagnosis of the disease is still based primarily on clinical observations. The 7 diagnostic criteria of the National Institutes of Health, which were established in 1988, include 3 skin manifestations (café-au-lait spots, freckling on flexural areas, and cutaneous neurofibromas).
