Abstract Background Erdheim–Chester disease (ECD) is a non-Langerhans histiocytosis that results in multi-organ disease involving the skin, bones, lungs and kidneys. Central nervous system (CNS) involvement occurs in about 50 % of patients, and diabetes insipidus, visual disturbances, and cerebellar ataxia are the most frequent neurological signs. We report a case of Erdheim-Chester disease with central nervous system involvement in the form of enhancing intracranial mass lesions with massive edema. Case presentation The patient presented with vertigo, ataxia, encephalopathy and pyramidal signs. Diagnosis was suggested by xanthomatous skin lesions and a biopsy was compatible with Erdheim-Chester disease demonstrating xanthogranulomas CD68 positive (clone KP1) and CD1a and S100 negative. Testing for BRAF mutation was negative, which precluded treatment with Vemurafenib. Treatment with steroids and interferon resulted in improvement of neurological signs and regression of edema on MRI. Conclusions The diagnosis of Erdheim-Chester disease should be considered in intracranial mass lesions. Xanthomatous skin lesions are a clue to the diagnosis.

Background: Erdheim-Chester disease (ECD) is a non-Langerhans cell histiocytosis, characterized by the infiltration of tissues by foamy CD68+CD1a- histiocytes, with 1500 known-cases since 90 years. Mutations activating the MAPK pathway are found in more than 80% of ECD patients, mainly the BRAFV600E in 57 to 70%. Central nervous system (CNS) involvement during ECD lead to significant morbidity and mortality. We assessed CNS manifestations in a French cohort of 253 ECD patients. Since 2012, close to 200 patients worldwide with multi-systemic and refractory ECD (e.g. heart and/or CNS involvements) have benefited from BRAF and MEK inhibitors, which have proven highly beneficial. Methods: CNS manifestations were determined by clinical examination and brain and/or spine magnetic resonance imaging (MRI). Targeted therapy efficacy was assessed using physician and radiologist global assessment. Results: Ninety-seven (38%) among the 253 of the whole cohort of ECD patients had CNS involvement. CNS involvement was significantly associated with a younger age at diagnosis (mean 55.5 years) and at symptoms onset (mean 50.5 years), and also with the presence of the BRAFV600E mutation (in 77% of cases), xanthelasma (34%), and diabetes insipidus (36%). Median survival among patients with CNS involvement was significantly lower than in ECD patients without CNS involvement (124 months versus 146 months, p=0.03). Seventy-four CNS MRI were centrally reviewed, corresponding to 3 patterns: tumoral in 66%, degenerative in 50%, and vascular in 18%. Targeted therapy (BRAF and/or MEK inhibitors) was associated with improvement of symptoms in 43% of patients, and MRI improvement in 45%. Conclusions: CNS manifestations are typically associated with a poor prognosis in ECD. Three distinct patterns may be recognized: tumoral, degenerative, and vascular. Targeted therapy leads to clinical and/or imaging improvement in almost 50% of patients. OffLabel Disclosure: Targeted therapies such as BRAF inhibitor (vemurafenib) and MEK inhibitor (cobimetinib) are used in severe histiocytosis in EU but are off label

Abstract The family of juvenile xanthogranuloma family neoplasms (JXG) with ERK-pathway mutations are now classified within the “L” (Langerhans) group, which includes Langerhans cell histiocytosis (LCH) and Erdheim Chester disease (ECD). Although the BRAF V600E mutation constitutes the majority of molecular alterations in ECD and LCH, only three reported JXG neoplasms, all in male pediatric patients with localized central nervous system (CNS) involvement, are known to harbor the BRAF mutation. This retrospective case series seeks to redefine the clinicopathologic spectrum of pediatric CNS-JXG family neoplasms in the post-BRAF era, with a revised diagnostic algorithm to include pediatric ECD. Twenty-two CNS-JXG family lesions were retrieved from consult files with 64% (n = 14) having informative BRAF V600E mutational testing (molecular and/or VE1 immunohistochemistry). Of these, 71% (n = 10) were pediatric cases (≤18 years) and half (n = 5) harbored the BRAF V600E mutation. As compared to the BRAF wild-type cohort (WT), the BRAF V600E cohort had a similar mean age at diagnosis [BRAF V600E: 7 years (3–12 y), vs. WT: 7.6 years (1–18 y)] but demonstrated a stronger male/female ratio (BRAF V600E: 4 vs WT: 0.67), and had both more multifocal CNS disease ( BRAFV600E: 80% vs WT: 20%) and systemic disease (BRAF V600E: 40% vs WT: none). Radiographic features of CNS-JXG varied but typically included enhancing CNS mass lesion(s) with associated white matter changes in a subset of BRAF V600E neoplasms. After clinical-radiographic correlation, pediatric ECD was diagnosed in the BRAF V600E cohort. Treatment options varied, including surgical resection, chemotherapy, and targeted therapy with BRAF-inhibitor dabrafenib in one mutated case. BRAF V600E CNS-JXG neoplasms appear associated with male gender and aggressive disease presentation including pediatric ECD. We propose a revised diagnostic algorithm for CNS-JXG that includes an initial morphologic diagnosis with a final integrated diagnosis after clinical-radiographic and molecular correlation, in order to identify cases of pediatric ECD. Future studies with long-term follow-up are required to determine if pediatric BRAF V600E positive CNS-JXG neoplasms are a distinct entity in the L-group histiocytosis category or represent an expanded pediatric spectrum of ECD.

Abstract Objectives Erdheim-Chester disease (ECD) is a rare form of histiocytosis with a broad, non-specific clinical spectrum. Here, we retrospectively evaluated the clinical and pathologic characteristics, presence of the BRAF V600E mutation, treatment options and outcomes of Chinese patients diagnosed with ECD at our center. Methods Patients diagnosed with ECD between January 2010 and April 2015 at Peking Union Medical College Hospital were included for study. We evaluated baseline characteristics, reviewed histological material, and tested for the presence of the BRAF V600E mutation using immunohistochemistry and polymerase chain reaction (PCR). Results Sixteen patients were diagnosed with ECD. Median age at diagnosis was 47 years (range, 22-61 years). Median disease duration (from the first symptom to diagnosis) was 22.5 months (range, 3-100 months). The main sites of involvement included bone (93.8%), cardiovascular region (43.8%), skin (31.3%), central nervous system (25.0%), and ¡°hairy kidney¡± (25%). Thirteen patients displayed characteristic histological features, including foamy histiocyte infiltration of polymorphic granuloma and fibrosis or xanthogranulomatosis, with CD68-positive and CD1-¦Á- negative immunostaining. Three patients (designated 3, 5 and 10) displayed CD68-positive and CD1¦Á- negative histiocyte infiltration, but not the above histological characteristics, and were thus initially misdiagnosed as Rosai-Dorfman disease. All three cases were BRAFV600E mutation-positive, leading to revision of diagnosis as ECD. Diagnosis of ECD in each case was additionally supported by typical radiographic findings. The BRAF V600E mutation was detected in 68.8% patients using PCR and 50.0% patients with immunohistochemistry. Ten patients (62.5%) received IFN-¦Á as first-line treatment, 3 patients showed improvement, 3 remained stable, 3 were too early for evaluation and 1 died. Three patients (5, 10 and 11) underwent transsphenoidal pituitary lesion surgery but were not subjected to systemic treatment, owing to the absence of symptoms and disease activity post-surgery and remained stable after a median of 16 months (range, 6-30 months) from diagnosis. Thirteen patients (81.3%) were still alive at median follow-up of 14.5 months. Conclusion ECD remains a largely overlooked disease, and increased recognition by clinicians and pathologists is necessary for effective diagnosis and treatment. The presence of the BRAF V600E mutation may facilitate discrimination of ECD from other non-Langerhans cell histiocytoses. Table 1.

✓ The authors report two cases of Erdheim—Chester disease (ECD), an illness of unknown pathogenesis. Generally, this disease process involves the metaphyseal and diaphyseal portions of the long bones, the lungs, and the retroperitoneum; however, other tissues may be involved including the central nervous system (CNS). To date only two cases of CNS-related ECD have been reported. The present report adds to the literature by documenting two more recent cases of ECD involving the CNS. The clinical presentations of these cases, their radiological findings with special reference to magnetic resonance imaging, pathological determination, and clinical management are briefly reviewed.
