Background. The outcome of neonates with congenital cutaneous Langerhans cell histiocytosis (LCH) is variable. Observations. We report a case of LCH in a female premature neonate born at 33-week gestation. She had disseminated cutaneous lesions, which consisted of hemorrhagic papules and vesicles, with sparse healthy skin areas, and the hands and feet were contracted with scarring and blackened. She was in respiratory failure although no apparent pulmonary or bone lesions on X-rays were noted. Skin biopsy confirmed a diagnosis of LCH due to observation of CD1a+ Langerhans cells, which lacked expression of E-cadherin and CD56. The patient died 57 hours after birth. Conclusions. Based on this case and the literature survey, the outcome of premature babies with congenital cutaneous LCH lesions is noted to be unfavorable, with the majority of such cases suffering from multisystem disease.

Anterior Pituitary Hormone

Langerhans cell histiocytosis (LCH) is a disorder of the mononuclear phagocyte system that can affect almost any organ and system. The most common central nervous system (CNS) manifestation in LCH is the infiltration of the hypothalamic-pituitary region leading to destruction and neurodegeneration of CNS tissue. The latter causes the most frequent endocrinological manifestation, that is, central diabetes insipidus (CDI), and less often anterior pituitary hormone deficiency (APD). The reported incidence of CDI is estimated between 11.5 and 24% and is considered a risk factor for neurodegenerative disease and APD. Three risk factors for development of CDI are recognized in the majority of the studies: (1) multisystem disease, (2) the occurrence of reactivations or active disease for a prolonged period, and (3) the presence of craniofacial bone lesions. Since CDI may occur as the first manifestation of LCH, differential diagnosis of malignant diseases like germ cell tumours must be made. APD is almost always associated with CDI and can appear several years after the diagnosis of CDI. Growth hormone is the most commonly affected anterior pituitary hormone. Despite significant advances in the knowledge of LCH in recent years, little progress has been made in preventing long-term sequelae such as those affecting the hypothalamic-pituitary system.

Underlying Pathology

Summary Histiocytoses comprise a group of diverse diseases of unknown etiology with various clinical presentation and evolution. The underlying pathology is characterised by accumulation and infiltration of variable numbers of cells of the monocyte-macrophage line in the affected tissues and organs. Histiocytoses are divided into three major classes: Langerhans cell histiocytosis (LCH), non- Langerhans cell histiocytosis, and malignant histiocytic disorders. The term LCH (also known in the past as histiocytosis X) encompasses the following rare diseases: Eosinophilic Granuloma, Hand-Schuller-Christian disease, Letterer-Siwe disease, Hashimoto-Pritzker disease, in which accumulation of pathologic Langerhans cells (LCs) leads to tissue damage. LCs usually reside in the skin and ensure protection against infections by destroying foreign substances. LC accumulation is caused by antigen stimulation and inadequate immune response. Thus, clinical LCH manifestations range from isolated disease with mono- or multifocal bone lesions to disseminated multisystem disease. LCH is a rare disease, affecting mainly children and young smokers, aged 20-50 years. Lung involvement in LCH usually presents as a mono-system disease and is characterized by Langerhans cell granulomas (LCG) infiltrating and impairing the distal bronchioles. The definite diagnosis is based on lung biopsy of CAT selected LCG areas. So far, there is no an effective treatment, but the better understanding of the mechanisms involved in the pathogenesis of the disease would help in the development of effective therapeutic strategies in the future.

Langerhans cell histiocytosis is a rare hematologic disease due to multiplication and accumulation of Langerhans cells, which are immature dendritic cells. The clinical presentation is highly variable and can range from isolated, self-healing skin or bone lesions to life-threatening multisystem disease. We report 2 cases confirmed by Histological and immunohistochemical evaluation of temporal bone biopsies. The first case is a 2-year-old child with chronic bilateral otorrhea and polyuria-polydipsia syndrome. Physical examination showed bilateral retroauricular redness and induration with filling all of the right and left external ear canal. Computed tomography showed osseous lysis of the temporal bone bilaterally. Magnetic resonance imaging of the brain showed the presence of pituitary infiltration. The second case is 2-year-old girl with chronic left otorrhea. Clinical examination objectified the presence of redness and induration in the left mastoid with the presence of an inflammatory polyp filling the entire left external auditory canal. Computed tomography revealed a left temporal bone lysis. Both patients were treated with chemotherapy.

Background: Bone is the most common organ of involvement in patients with Langerhans cell histiocytosis (LCH), which is often painful and associated with significant morbidity from pathological fractures. Current first-line treatments include chemotherapy and steroids that are effective but often associated with adverse effects, whereas the disease may reactivate despite an initial response to first-line agents. Bisphosphonates are osteoclast inhibitors that have shown to be helpful in treating bone lesions of LCH. To date, there are no large international studies to describe their role in treating bone lesions of LCH. Method: We conducted a multicenter retrospective review of 13 patients with histologically proven LCH, who had received bisphosphonates either at diagnosis or at disease reactivation. Results: Ten patients (77%) had a single system bone disease, and 3 (23%) had bone lesions as part of multisystem disease. Median follow-up time post-bisphosphonate therapy was 4.6 years (range, 0.8 to 8.2 years). Treatment with bisphosphonates was associated with significant pain relief in almost all patients. Twelve  (92%) achieved resolution of active bone lesions, and 10 out of them had no active disease for a median of 3.5 years (range, 0.8 to 5 years). One patient did not respond. No major adverse effects were reported in this series.  Conclusion: Bisphosphonates are well-tolerated drugs that can significantly improve bone pain and induce remission in active bone LCH. Future prospective studies evaluating the role of bisphosphonates in LCH are warranted.

Abstract Introduction: Langerhans cell histiocytosis (LCH) is a monoclonal disorder characterized by proliferation and accumulation of atypical Langerhans cells and in up to 55% of all cases somatic mutations in BRAF proves to be the driver. Although uncommon, it is potentially fatal and carries significant morbidity. Bone involvement in LCH can be destructive, painful and often associated with pathologic fractures. There is no consensus in the treatment strategies for bone LCH which could vary from simple curettage with biopsy and/or intralesional steroids to more toxic systemic chemotherapy. However, the number of treatments for this disease is limited and other options need to be explored. Bisphosphonates are osteoclast inhibitors that can target certain osteoclast markers expressed by the multinucleated giant cells in the skin, bone and lymph nodes LCH lesions and can potentially be used to alleviate bone pain and possibly control the progression of disease activity. Purpose: To evaluate the efficacy and safety of bisphosphonates in treating bone LCH and extra-osseous disease. Methods: An international multicenter retrospective chart review was conducted in children and adults with LCH who received bisphosphonates between 1995 and 2014. Results: Eighteen patients were identified from 4 centers. All received bisphosphonates therapy either at diagnosis or at ≥ 1st reactivation. Median age at start of bisphosphonates was 23.7 years (range 5.7-38.3 years), and median follow-up time post-bisphosphonate therapy was 2.8 years (range 0.9-5.0 years). Patients had either single system bone disease or bone lesions as part of their multisystem disease. Patients were treated with different bisphosphonates with majority received zoledronic acid (n=10), followed by pamidronate (n=4) and alendronate (n= 3); one patient received both pamidronate and zoledronic acid. All patients reported significant reduction in pain to either no or mild pain after administration of bisphosphonates. Thirteen of 18 patients (72%) achieved complete remission (CR) in their bone lesions, including lesions in skin (n=1), lung (n=1) and pituitary (n=1); 2 had partial response and 3 had no response. Among the 13 CR patients, 12 had no active disease for a median of 4.1 years (range 2.8 - 5.1 years) and 1 developed radiographic neurodegeneration after 2 years. Bisphosphonate therapy was well tolerated by all patients with no major toxicity. Progression-free survival (PFS) was 75 ± 11% at 3 years, with a trend favoring better PFS (P=0.24) in patients with no or first reactivation compared with those having ≥ 2 reactivations. Conclusion: Bisphosphonates is a well-tolerated medication that can significantly improve bone pain in patients with bone LCH, and may even be effective in treating extra-osseous disease. A prospective randomized trial evaluating the role of bisphosphonates in multifocal bone LCH is warranted. Disclosures No relevant conflicts of interest to declare.

Langerhans cell histiocytosis (LCH) is a rare disease of the monocyte-macrophage system. Although it is known that bone involvement is seen very frequently in cases with LCH, our case is the first case with a lytic-destructive lesion in the bone structure forming sella turcica. A 4-year-old, 5-month-old male patient who applied to our outpatient clinic was diagnosed with Langerhans cell histiocytosis in further examination after the diagnosis of central diabetes insipidus (CDI) was made. On cranial magnetic resonance imaging (MRI), widespread lytic-destructive bone lesions were observed in the bone structure forming the sella (sphenoid bone), sellar destruction not previously described in the literature. Sellar erosion has not been reported before in cases diagnosed with LCH in the literature. The presence of low-grade fever in a patient presenting with isolated CDI is a warning sign for the diagnosis of LCH.

Introduction: Langerhans Cell Histiocytosis (LCH) is a rare form of cancer that mostly affects children and rarely adults. LCH involves an abnormal clonal proliferation of Langerhans cells in the bone marrow. These cells are capable of migrating from the skin to lymph nodes. Therefore, it is characterized as a multisystem disease. Neurological manifestations are not common, and often patients’ present with endocrine dysfunction with neuroimaging findings of hypothalamic and pituitary masses can mimic pituitary adenoma. Here, we discuss two instances of unusual adult-onset, primary neurological LCH in patients with a positive response to therapy-these two patients presented with mass lesion and neurodegenerative form of LCH, respectively. LCH can manifest features of mass lesions or neurodegeneration on brain Magnetic Resonance Imaging (MRI). Since it is rare in adults, it is crucial to identify this condition as timely treatment can have a better prognosis.

Abstract Background Lung involvement in childhood Langerhans cell histiocytosis (LCH) is infrequent and rarely life threatening, but occasionally, severe presentations are observed. Methods Among 1482 children (< 15 years) registered in the French LCH registry (1994–2018), 111 (7.4%) had lung involvement. This retrospective study included data for 17 (1.1%) patients that required one or more intensive care unit (ICU) admissions for respiratory failure. Results The median age was 1.3 years at the first ICU hospitalization. Of the 17 patients, 14 presented with lung involvement at the LCH diagnosis, and 7 patients (41%) had concomitant involvement of risk-organ (hematologic, spleen, or liver). Thirty-five ICU hospitalizations were analysed. Among these, 22 (63%) were secondary to a pneumothorax, 5 (14%) were associated with important cystic lesions without pneumothorax, and 8 (23%) included a diffuse micronodular lung infiltration in the context of multisystem disease. First-line vinblastine–corticosteroid combination therapy was administered to 16 patients; 12 patients required a second-line therapy (cladribine: n = 7; etoposide-aracytine: n = 3; targeted therapy n = 2). A total of 6 children (35%) died (repeated pneumothorax: n = 3; diffuse micronodular lung infiltration in the context of multisystem disease: n = 2; following lung transplantation: n = 1). For survivors, the median follow-up after ICU was 11.2 years. Among these, 9 patients remain asymptomatic despite abnormal chest imaging. Conclusions Severe lung involvement is unusual in childhood LCH, but it is associated with high mortality. Treatment guidelines should be improved for this group of patients: viral infection prophylaxis and early administration of a new LCH therapy, such as targeted therapy.

Abstract Abstract 4715 Non-Langerhans-cell-histiocytosis (Non-LCH) represents a rare disorder with a broad spectrum of clinical features and various outcome. We here report on a 61 years old man with Non-LCH with severe skin and bone marrow involvement. At the time of diagnosis in 2006, the patient presented with up to four centimeter large cutaneous papules involving face, stem, hands and feet. Since two years, the patient also developed an increasing tricytopenia due to an extensive bone marrow infiltration of histiocytes (80%). Since diagnosis, the patient received a large number of various therapies including daily glucocorticoids at different dosages (continuously since diagnosis), low-dose methotrexate (10-40mg s.c. per week; from may to september 2007), experimental treatment with lenalidomide (5-10mg per day; from february to june 2008), continous oral trofosfamide (100mg per day; from july to august 2008), cladribine monotherapy (2,1mg/m2 d1-5; 4 cycles; from December 2008 to march 2009) and the combination of cladribine (2.1mg/m2 d1-5) and cytarabine (40 mg s.c. d1-7; 3 cycles; from january to march 2010). The patient did not respond to any of these therapies. Due to the persistent distinctive clinical symptoms (massive skin involvement, tricytopenia), we started in July 2010 an experimental therapy with sorafenib at a dosage of 200mg per day for four days, followed by 400mg per day for another four days, and subsequently increased the dosage to 800mg daily. After four weeks, the marked skin papules flattened to skin level at all preferential sites. Small skin ulcers at the cheeks healed up. In parallel, there was a significant improvement of hematopoiesis since start of therapy with haemoglobin levels raising from 8,6g/dl to 12,2g/dl and normalization of leukocyte count (from 3.1/nl to 5.2/nl). Bone marrow rebiopsy is intended after three month of therapy, data on the actual grade of infiltration will be presented at the meeting. Based on the impressive clinical improvement under sorafenib, we analyzed selected target genes of the multityrosine kinase inhibitor: mutation screening was performed on the FLT3 (internal tandem duplication, point mutations of the tyrosine kinase domain) and KIT genes (exon 8 and exon 17) as well as for the recently described BRAF V600E mutation found in a significant number of patients with LCH (G. Badalian-Very et al., Blood prepublished online June 2, 2010; DOI 10.1182/blood-2010-04-279083). However, in none of these genes, mutations were found and further molecular analysis of the patient's bone marrow is currently under investigation. To our knowledge, this is the first report on the efficacy of sorafenib in a case of histiocytosis. However, the underlying genetic mechanisms of Non-LCH still have to be elucidated. Disclosures: Off Label Use: Sorafenib is approved for unresectable hepatocellular carcinoma and advanced renal cancer. We present an off-label use of sorafenib in a case of a severe orphan disease refractory to all standard therapies. Zenz:Roche: Honoraria; Boehringer: Honoraria; GSK: Honoraria; Celgene: Honoraria.

The Central Nervous System

Langerhans cell histiocytosis (LCH) is a rare disease with hitherto unknown etiology and pathogenesis. It is extremely rare for clinicians to encounter histiocytic lesions of the central nervous system (CNS); the proportion of cases of which is only 1–4% of all polysystemic and multifocal bone lesions. The paper describes a clinical case of fixation amnesia in a female patient with focal brain lesions in LCH. It depicts the most characteristic clinical features and presents an algorithm for the diagnosis of histiocytic brain lesion. The results of the experimental psychological examination of the patient are considered in detail and the clinical presentations of fixation amnesia are described. There are neuroimaging data showing the lesions in the hypothalamic-pituitary region and temporal bone, which involve the auditory structures. The clinical findings have led to the conclusion that both the clinical and neuroimaging patterns of histiocytic lesions in the CNS are non-specific, which complicates the diagnostic search in LCH. For correct diagnosis and timely treatment, it is necessary to perform a biopsy of the pathological focus, followed by histological and immunohistochemical examination of the material.
