A Rare Case of Erdheim-Chester Disease (Non-Langerhans Cell Histiocytosis) with Concurrent Langerhans Cell Histiocytosis: A Diagnostic and Therapeutic Challenge [PDF]

Case Reports in Hematology, 2018
Erdheim-Chester disease (ECD) is a rare non-Langerhans cell histiocyte disorder most commonly characterized by multifocal osteosclerotic lesions of the long bones demonstrating sheets of foamy histiocyte infiltrates on biopsy with or without histiocytic ...

Intra-arterial Melphalan for Neurologic Non-Langerhans Cell Histiocytosis. [PDF]

Neurology, 2021
Histiocytic neoplasms are rare hematologic disorders characterized by pathologic infiltration of activated histiocytes in affected tissues. The treatment of histiocytic neoplasms, including Langerhans cell histiocytosis (LCH) and non-LCH, has advanced in recent years owing to targeted kinase inhibitors (BRAF and MEK) as patients with somatic mutations ...

Intermediate-dose cytarabine is an effective therapy for adults with non-Langerhans cell histiocytosis [PDF]

Orphanet Journal of Rare Diseases, 2022
Background Non-Langerhans cell histiocytosis, including Erdheim–Chester disease (ECD), Rosai–Dorfman disease (RDD), indeterminate cell histiocytosis (ICH), and unclassified histiocytosis, is a rare disorder lacking a standard treatment strategy.

Case of Non-Langerhans Cell Histiocytosis in a Person Living with HIV - Clinical and Therapeutic Challenge [PDF]

Journal of the International Association of Providers of AIDS Care, 2022
Non-Langerhans cell histiocytosis is a rare disease which seldom affects adults. We report a case of a 32-year-old Bulgarian woman living with HIV. She developed severe anemia, extreme splenomegaly, requiring splenectomy and vertebral tumor formations ...

High prevalence of myeloid neoplasms in adults with non-Langerhans cell histiocytosis. [PDF]

Blood, 2017
Key Points Some 10.1% of adults with non–Langerhans cell histiocytosis have a concomitant myeloid neoplasm with each often harboring distinct mutations. The presence of distinct kinase mutations in histiocytosis and myeloid neoplasms resulted in discordant responses to targeted therapy.

Molecular Profiling of Tumor Tissue and Plasma Cell-Free DNA from Patients with Non-Langerhans Cell Histiocytosis. [PDF]

Mol Cancer Ther, 2019
Abstract The BRAFV600E mutation and BRAF inhibitor responsiveness characterize ∼50% of patients with the non-Langerhans cell histiocytosis (non-LCH) Erdheim–Chester disease (ECD). We interrogated the non-LCH molecular landscape [ECD, n = 35; Rosai–Dorfman disease (RDD), n = 3; mixed ECD/RDD, n = 1] using BRAFV600E PCR and/or next ...

MEK Inhibition with Trametinib in Patients with Non-Langerhans Cell Histiocytosis

Blood, 2019
Background: Activation of the MAPK pathway through BRAF mutations or other molecular alterations is a hallmark of the non-Lagerhans cell histiocytosis (non-LCH) such Erdheim-Chester disease (ECD) or Rosai-Dorfman disease (RDD). Conventional clinical molecular testing of tumor tissue fails to identify targetable molecular alteration in about one third ...

Non-Langerhans cell histiocytosis in a child with Kawasaki disease

Case Reports, 2009
Polymorphous skin rashes are one of the major presentations in children with Kawasaki disease. This report describes an unusual presentation of a skin rash (non-Langerhans cell histiocytosis) in a 4-month-old baby with resistance to intravenous immunoglobulin (IVIG) treatment and coronary artery dilatation.

Successful treatment of non-Langerhans cell histiocytosis with the MEK inhibitor trametinib: a multicenter analysis

Blood Advances, 2023
Abstract Erdheim-Chester disease (ECD) and Rosai-Dorfman disease (RDD) are rare non-Langerhans cell histiocytoses (non-LCHs), for which therapeutic options are limited. MAPK pathway activation through BRAFV600E mutation or other genomic alterations is a histiocytosis hallmark and correlates with a favorable response to BRAF inhibitors ...
