    Department of Otorhinolaryngology, Tengku Ampuan Rahimah Hospital, Klang, Selangor, Malaysia.
    Langerhans cell histiocytosis (LCH) is a rare proliferative disorder, which commonly arises in the bone and may involve other systems. To date, the diagnosis of temporal bone LCH remains a challenge as it may masquerade as a common ear infection.

    Frequency of MAP2K1, TP53, and U2AF1 Mutations in BRAF-mutated Langerhans Cell Histiocytosis: Further Characterizing the Genomic Landscape of LCH.
    Am J Surg Pathol 2018 Apr 11. Epub 2018 Apr 11.
    Department of Pathology, University of Chicago, Chicago, IL.
    Langerhans cell histiocytosis is a proliferative disorder of neoplastic Langerhans cells with activating mutations in the Erk signaling pathway. TP53 and U2AF1 mutations have been implicated in other myelomonocytic malignancies and we hypothesized that mutations in these genes may cosegregate in LCH patients according to BRAF mutation status. Towards this end, we collected cases with a pathologic diagnosis of Langerhans cell histiocytosis from Stanford University Hospital. Read More

    Department of Pathology, Memorial Sloan Kettering Cancer Center, New York, NY, United States; Human Oncology and Pathogenesis Program, Memorial Sloan Kettering Cancer Center, New York, NY, United States. Electronic address:
    The systemic histiocytoses encompass a clinically heterogeneous group of disorders leading to tissue damage secondary to the accumulation and infiltration of pathological cells thought to be derived from the dendritic or monocytic lineages with accompanying inflammation. For decades, whether or not the histiocytoses were inflammatory or neoplastic disorders was unclear, and their cellular origins have long been obscure and heavily debated. However, the rise of the molecular era led to the discovery of recurrent BRAF mutations in approximately 50% of patients with Langerhans cell and non-Langerhans cell histiocytoses, which provided the first convincing evidence that these are indeed histiocytic neoplasms.
