    Department of Dermatology, University Hospital Zürich, Zürich, Switzerland.
    Histiocytoses are rare disorders characterized by the accumulation of cells derived from macrophages, dendritic cells, or monocytes in various tissues. There is a broad spectrum of disease manifestations with some subtypes commonly showing skin lesions while in others the skin is rarely involved. Here we describe cutaneous manifestations of histiocytoses belonging to the Langerhans group (L group), the group of cutaneous and mucocutaneous histiocytoses (C group) and the group of Rosai-Dorfman disease and related histiocytoses (R group) according to the current classification.

    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 Aug 15;92(8):394-397. 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 Jul;8(28):46065-46070
    Texas Children's Cancer Center, Texas Children's Hospital, Houston, TX 77030, USA.
    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
