Histiocytoses constitute a heterogeneous group of rare disorders, characterised by infiltration of almost any organ by myeloid cells with diverse macrophage or dendritic cell phenotypes. Histiocytoses can start at any age. Diagnosis is based on histology in combination with appropriate clinical and radiological findings.

Langerhans Cell Histiocytosis With <i>MAP2K1<sup>E102_I103del</sup></i> Mutation Successfully Treated With Trametinib. [PDF]
ABSTRACT The discovery of the MAPK pathway mutations in lesions of patients with Langerhans cell histiocytosis (LCH) has made targeted therapy an important therapeutic approach for these patients. Theoretically, the RAF‐independent mutation MAP2K1E102_I103del is naturally resistant to allosteric MEK inhibitors.

Erdheim-Chester Disease Manifesting Without Long Bone Involvement. [PDF]
We present an atypical case of Erdheim–Chester Disease (ECD) due to the absence of skeletal involvement despite widespread infiltration of other organs. ABSTRACT Erdheim–Chester Disease (ECD) is an extremely rare, non‐Langerhans cell histiocytosis characterised by the proliferation of foamy histiocytes infiltrating various organs.

Quantitative Brain MRI Analysis in Neurodegenerative Langerhans Cell Histiocytosis. [PDF]
ABSTRACT Background Neurodegenerative Langerhans Cell Histiocytosis (ND‐LCH) is a severe central nervous system involvement complicating LCH. ND‐LCH is characterized by a cerebellar ataxia, pyramidal signs, pseudobulbar palsy, cognitive impairment, and behavioral disturbances.

Langerhans cell histiocytosis in adults: literature review
Langerhans cells histiocytosis is a variant of malignant histiocytosis. The course and symptoms vary. patients with localized forms have a better prognosis, because local therapy is effective.
