Abstract
In the twenty- first century, there is widespread agreement that in addition to lung cancer, emphysema, and chronic bronchitis, cigarette smoking causes accumulation of pigmented macrophages, interstitial fibrosis, and Langerhans cell proliferation in various permutations. These histologic changes remain subclinical in some patients and produce clinical manifestations and imaging abnormalities in others. Debate surrounds terminology of these lesions, which are often grouped together under the umbrella of "smoking-related interstitial lung disease." This review summarizes modern concepts in our understanding of these abnormalities and explains how the recognition of smoking-related interstitial fibrosis has advanced the field.

AMERICAN JOURNAL OF CASE REPORTS 2024; 25:e942681. [PMID: 38764221 PMCID: PMC11117437 DOI: 10.12659/ajcr.942681] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Revised: 04/02/2024] [Accepted: 01/25/2024] [Indexed: 05/21/2024]
Abstract
BACKGROUND Langerhans cell histiocytosis (LCH) is a rare and uncontrolled proliferation of dendritic cells of myeloid origin. The incidence of LHC was estimated at 5 cases per million children ages 0-15 years old. The most common places for this tumor are the jaw, vertebra, pelvis, and the extremities. The disease with multisystem involvement can present a mortality rate of 20% and one-third of children have multisystem involvement. We present a case with unusual bone involvement of the anterior cranial base with a challenging diagnosis and a complex surgical approach. CASE REPORT We report the case of a 6-year-old boy who manifested the disease with daily holocranial headache, worse in the frontal region and refractory to analgesia for 10 days, strabismus homonymous, diplopia, and right palpebral ptosis. The tumor affected the sphenoid sinus, internal carotid artery, and sella turcica, and made contact with the pituitary gland. A joint surgery with Otorhinolaryngology and Neurosurgery was performed by nasal endoscopic access to the skull base by means of the right medial turbinectomy (for the access) and right sphenoid opening, septectomy and opening of the left sphenoid to work with 4 hands and, after resection of lesion, inside the sphenoid. CONCLUSIONS This patient had rare bone involvement from LCH and atypical clinical presentation next to the important and delicate structures of the anterior skull base, but had a satisfactory outcome.

From terminal ileum to terminal diagnosis: The critical role of terminal ileum intubation in diagnosing langerhans cell histiocytosis in a patient with TAR syndrome. Radiol Case Rep 2024; 19:2052-2057. [PMID: 38444598 PMCID: PMC10914551 DOI: 10.1016/j.radcr.2024.02.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2023] [Revised: 01/29/2024] [Accepted: 02/05/2024] [Indexed: 03/07/2024] Open
Abstract
The co-occurrence of Thrombocytopenia with Absent Radius (TAR) syndrome and Langerhans Cell Histiocytosis (LCH) is exceedingly rare, with scant documentation in existing medical literature. This case report aims to shed light on this unique intersection of conditions, emphasizing the diagnostic and therapeutic challenges it presents. A 27-year-old female with a history of TAR syndrome presented with microcytic anemia, hip pain, and gastrointestinal symptoms. Terminal ileum intubation during colonoscopy revealed superficial ulcerations, leading to a biopsy that confirmed LCH. Subsequent radiologic investigations, including CT and MRI, showed multiple osseous lesions in the pelvis, sacrum, and skull. A treatment plan involving IV Cytarabine was initiated due to concerns of CNS involvement, as indicated by mastoid air cell involvement and symptoms of dizziness and ear fullness. The case highlights the diagnostic value of terminal ileum intubation during colonoscopy, which was pivotal in diagnosing LCH in this patient. It also discusses the use of IV cytarabine, a chemotherapy drug that inhibits DNA synthesis, as a suitable treatment option given the suspected CNS involvement. The case adds to the limited literature on the natural history and management of adult patients with LCH, particularly in the context of TAR syndrome. This case report serves as a compelling addition to medical literature, highlighting the diagnostic complexities and treatment considerations in a patient with both TAR syndrome and LCH. It emphasizes the importance of comprehensive diagnostic approaches, including terminal ileum intubation during colonoscopy, and introduces IV cytarabine as a viable treatment option for cases with suspected CNS involvement.

Langerhans Cell Histiocytosis Mimicking a Meningeal Lesion with Temporal Bone and Muscle Compromise in an Adult Patient: A Case Report. J Neurol Surg Rep 2024; 85:e43-e47. [PMID: 38690582 PMCID: PMC11060841 DOI: 10.1055/s-0044-1786360] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2024] [Accepted: 03/25/2024] [Indexed: 05/02/2024] Open
Abstract
Introduction Langerhans cell histiocytosis (LCH) is a rare proliferative systemic disease characterized by the growth of abnormal dendritic cells and wide-ranging organ involvement. This condition can affect individuals of all ages, but most commonly children, with a peak incidence in toddlers. Symptoms may vary depending on the affected organ or system. Case Report A 43-year-old man presented with a left temporal stabbing headache unresponsive to management with therapy and nonsteroidal anti-inflammatory drugs. Initial evaluation revealed a contrast-enhanced left temporal extra-axial lesion with bone and muscle compromise. Differential diagnoses, including multiple myeloma, were explored. Initial laboratory tests and imaging studies showed no other abnormalities, except for splenomegaly and a residual granuloma in the left lung. En bloc resection of the lesion was recommended. The patient underwent surgical intervention, which included resection of the dural lesion and all borders of an infiltrating tumor within the temporalis muscle and the affected portion of the left temporal bone. Posterior pathological examination revealed LCH. Postoperative course was uneventful. Follow-up appointments were scheduled after pathology results confirmed the diagnosis. Patient has continued follow-up for the following 3 months after the surgical procedure. Further evaluations are pending. Discussion This case report corresponds to a patient with LCH. These patients are individualized and stratified based on local or systemic involvement to determine the most appropriate type of management. This is a rare case as LCH is rare in older patients and the initial presented lesion initially mimicked a meningioma; however, its atypical behavior and associated lytic compromise led to consideration of possible differential diagnoses. Conclusion LCH can present with lytic bone lesions, mimicking other conditions, including infiltrative neoplastic lesions. Early diagnosis and appropriate surgical management are essential for optimal patient outcomes. Long-term follow-up is crucial to monitor disease progression and response to treatment.

Abstract
Background Langerhans cell histiocytosis is a rare disease characterized by the abnormal proliferation of Langerhans cells within a single organ or multiple organs. This case report aims to improve the knowledge of the presentation of gastrointestinal Langerhans cell histiocytosis to facilitate the diagnosis and management of this rare disorder. Case presentation A 19-month-old female presented with repeatedly mucinous bloody stools. The abdominal ultrasound revealed a slightly enlarged spleen. The initial colonoscopy revealed chronic enteritis with a very early onset inflammatory bowel disease. After anti-inflammatory treatment without improvement, an intestinal biopsy was performed at The Forth Affiliated Hospital of Zhejiang University. The final intestinal biopsy and histopathology examination confirmed the presence of Langerhans cell histiocytosis. After diagnosis, additional lung and head imaging examinations revealed no abnormalities. Her condition improved gradually after being treated with chemotherapy (vincristine and prednisone) and molecular-targeted drug(dalafinil) treatment. Conclusion The clinical symptoms of Langerhans cell histiocytosis involving the gastrointestinal tract are not specific and may resemble symptoms observed in inflammatory bowel disease and other primary gastrointestinal tumors. Therefore, in cases of infants presenting with inflammatory gastrointestinal symptoms that do not resolve after treatment, a biopsy is essential to obtain a differential diagnosis.

Abstract
BACKGROUND Feline pulmonary Langerhans cells histiocytosis (PLCH) is a rare disorder that results in progressive respiratory failure secondary to pulmonary parenchymal infiltration with Langerhans cells (LCs). A diagnosis of PLCH is proposed based on the clinical features and pathological findings and confirmed based on the infiltrating histiocytic cells. There are few documented cases of feline PLCH, and this case report of PLCH in an African Lion could present new information and aspects of this feline histiocytic disease. CASE PRESENTATION An African lion at Hohhot Zoo showing severe hyporexia and dyspnea with subsequent mental depression and emaciation died of exhaustion after a 35-day course of illness. Empirical treatment did not have a significant effect. An autopsy revealed that the lungs were enlarged and hardened due to infiltrative lesions, with many yellowish-white foci in all the lobes and sections. Furthermore, the kidneys were atrophied and had scattered grayish-white lesions on the surface. At the same time, congestion was widely distributed in various locations, including the liver, subcutaneous loose connective tissues, serosal surface and other tissues and organs. Histologically, proliferative histiocytic cells (PHCs) were scattered in the alveolar cavities, bronchioles and submucosa of bronchioles, with evident cellular and nuclear pleomorphism, and thus the alveolar septa were obliterated. The histopathological changes in other organs included chronic sclerosing glomerulonephritis, proliferated Kupffer cells in the liver, adrenal edema and interstitial connective tissue hyperplasia, as well as atrophy of the small intestines and spleen. Furthermore, immunohistochemical analysis results were strongly positive for CD1a, vimentin, S100 and E-cadherin in the membrane or cytoplasm of PHCs, supporting an LC phenotype. CONCLUSIONS Here, we present a rare pulmonary Langerhans cell histiocytosis case in an African lion.

Abstract
OBJECTIVE To describe the cerebrospinal fluid (CSF) metabolomic pattern of pituitary stalk lesions. METHODS CSF was collected from patients with different pituitary stalk lesions treated at Peking Union Medical College Hospital: germ cell tumor (GCT, n = 27); hypophysitis (n = 10); and Langerhans cell histiocytosis (LCH) or Erdheim-Chester disease (ECD) (LCH + ECD, n = 10). The CSF metabolome profiles were characterized by liquid chromatography-mass spectrometry (LC-MS). RESULTS There were 44 metabolites that significantly differed between patients with GCT and those with hypophysitis (P < .05). Between patients with GCT with CSF level of beta subunit of human chorionic gonadotrophin (β-hCG) < 5 mIU/mL and those with hypophysitis, there were 15 differential metabolites (P < .05, fold change > 1.5 or < 1/1.5). All of the metabolites had an area under the curve (AUC) above 0.7. There were 9 metabolites that significantly differed between patients with GCT and those with LCH + ECD (P < .05) and 7 metabolites had significant differences between GCT (CSF β-hCG < 5 mIU/mL) and LCH + ECD (P < .05, fold change > 1.5 or < 1/1.5). We found 6 metabolites that were significantly different between patients with hypophysitis and those with LCH + ECD (P < .05) and 5 of these had fold change more than 1.5 or less than 1/1.5. Three metabolites, 5-deoxydiplosporin, cloversaponin I, and phytosphingosine, showed excellent capabilities to differentiate the 3 disease categories. Furthermore, we identified 67 metabolites associated with clinical test results (ρ > 0.2, P < .05) and 29 metabolites showed strong correlation (ρ > 0.4, P < .05). CONCLUSION Our study is the first to systematically investigate the metabolomics of CSF in different pituitary stalk lesions. CSF metabolomics is a useful strategy for biomarker discovery.

Abstract
Introduction Langerhans cell histiocytosis (LCH) is a rare hematologic condition which can affect multiple organ systems and has variable presentation. LCH is more commonly seen as a malignancy of childhood. LCH in adulthood can have poor outcomes depending on the involvement of critical organs. Case Presentation We report a case of a 71-year-old female who presented with progressive weakness, weight loss, diarrhea, and jaundice, and had been undergoing outpatient workup for elevated liver enzymes for the last 2 years. She required admission to the intensive care unit for vasodilatory shock, requiring vasopressor and chronotropic support. Imaging showed an underlying multiorgan process involving the gastrointestinal tract, liver, spleen, and central nervous system. A repeat liver biopsy after a prior inconclusive one revealed the diagnosis of multisystem LCH presenting as secondary sclerosing cholangitis. Conclusion The uniqueness of this multisystem LCH case lies not only in its rarity but also in the diagnostic journey that necessitated a repeat biopsy for a conclusive diagnosis. Early identification and targeted intervention can help in ensuring better patient outcomes, especially when the presentation can overlap with various other possible conditions.

Abstract
Langerhans cell histiocytosis (LCH) is a group of unexplainable abnormal proliferation and aggregation of Langerhans cell. LCH can be classified into four clinical variants: Letterer-Siwe disease, Hand-Schüller-Christian disease, eosinophilic granuloma, and congenital self-healing LCH. LCH is most prevalent in children. Lesions can be localized in a single system or multiple organs, and clinical manifestations vary depending on the affected organs. The skin and mucocutaneous tissues are the starting point of the affected tissue. This study presents a LCH case characterized by transient self-healing. This case can further provide references for the clinical diagnosis and treatment of LCH.

Abstract
Langerhans cell histiocytosis (LCH) is a neoplastic disorder derived from LCH precursor cells that can manifest as a single-system disease or a multisystem disorder. While extensively studied in children, LCH has received less attention in adult patients. We aimed to investigate the pathology and clinical course of LCH in adults presenting with a bone lesion. Cases of osseous LCH diagnosed in patients ≥18 in our center were analyzed. Histologic slides were reviewed, and clinical data were collated. Molecular analysis for BRAF mutation was performed in a subset. Twelve osseous LCH cases with classic morphology and CD1a+/S100+ immunophenotype were identified. Tumors occurred in six females and five males with a median age of 34 years (range: 18-77 years) and involved the craniofacial bones (4), pelvis (3), spine (2), appendicular skeleton (2), and rib (1). Radiographically, tumors appeared as ill-defined lytic lesions, often accompanied by cortical erosion and soft tissue extension, with pain being the most common presentation. On staging work-up with available data, two patients had multifocal bone lesions, two had multi-system disease, and four had solitary lesions. Two patients had prior or concurrent neoplasms, and 63 % of patients (5 out of 8) had a history of smoking. BRAF mutational analysis performed in six cases revealed a BRAFV600E mutation in one, negative result in one, and failed in four archived specimens. Our study highlights the importance of performing staging in patients with adult-onset LCH presenting as a bone lesion, as the clinical extent of the disease can vary widely among individuals.

Abstract
Langerhans cell histiocytosis (LCH) is a rare disease characterized by clonal expansion of CD1a+ CD207+ myeloid dendritic cells. The features of LCH are mainly described in children and remain poorly defined in adults; therefore, we conducted a nationwide survey to collect clinical data from 148 adult patients with LCH. The median age at diagnosis was 46.5 (range: 20-87) years with male predominance (60.8%). Among the 86 patients with detailed treatment information, 40 (46.5%) had single system LCH, whereas 46 (53.5%) had multisystem LCH. Moreover, 19 patients (22.1%) had an additional malignancy. BRAF V600E in plasma cell-free DNA was associated with a low overall survival (OS) rate and the risk of the pituitary gland and central nervous system involvement. At a median follow-up of 55 months from diagnosis, six patients (7.0%) had died, and the four patients with LCH-related death did not respond to initial chemotherapy. The OS probability at 5 years post-diagnosis was 90.6% (95% confidence interval: 79.8-95.8). Multivariate analysis showed that patients aged ≥60 years at diagnosis had a relatively poor prognosis. The probability of event-free survival at 5 years was 52.1% (95% confidence interval: 36.6-65.5), with 57 patients requiring chemotherapy. In this study, we first revealed the high rate of relapse after chemotherapy and mortality of poor responders in adults as well as children. Therefore, prospective therapeutic studies of adults with LCH using targeted therapies are needed to improve outcomes in adults with LCH.

Abstract
RATIONALE Langerhans cell histiocytosis (LCH) is a kind of rare disease in which dendritic cells proliferate abnormally. It often occurs in children and can involve any tissue and organ. The affected sites usually include bone, skin, pituitary gland, and lungs, while the thyroid gland and external auditory canal are rarely observed. The perineal and labial involvement of this disease has not been reported yet. PATIENT CONCERNS A 47-year-old female patient experienced a swelling of the anterior neck area without an obvious inducement. She noticed a quail egg-like mass on the left side, and the mass increased progressively within 3 months. The anterior neck area was found to be swollen, and some flaky red rashes were seen on the scalp and bilateral external auditory canals. DIAGNOSES Imaging examination showed enlarged thyroid and cervical lymph nodes, multiple low-density nodules in the liver, and reduced signal in the posterior pituitary gland. The biopsy pathological result of the increased left cervical lymph node indicated that LCH was detected. INTERVENTIONS VP regimen (vincristine, dexamethasone per os) and related supportive treatments were given as inducing chemotherapy for 6 weeks. OUTCOMES After the second chemotherapy, the rash on the scalp and external auditory canal improved, and the neck mass was significantly reduced. After the third chemotherapy, the rash was mostly disappeared, while the neck lumps increased during chemotherapy. Thus, clatribine chemotherapy was recommended as the follow-up. LESSONS Imaging examinations played an important role in the diagnosis and follow-up of the disease, especially 18F-FDG PET/CT, which could show multiple involving organs at the same time. When a patient suffering from diabetes insipidus, skin rash, or fever, has a high FDG uptake PET/CT result in multiple tissues and organs throughout the body, it is necessary to consider the possibility of LCH.

Abstract
Background This study is aimed at exploring a case of choroidal Langerhans cell histiocytosis (LCH) successfully treated with systemic corticosteroid and immunosuppressant. Case presentation. A 24-year-old man with known multisystem LCH developed loss of vision, ocular pain, conjunctival injection, panuveitis, and a ciliochoroidal mass. After receiving an intravenous methylprednisolone pulse, oral high-dose corticosteroids, and methotrexate, the mass resolved quickly and completely without flare-ups during 6 months of follow-up. Conclusions Intraocular involvement of LCH is rare and can present with or without a history of multisystemic disease. The diagnosis is challenging, and the standard treatment is not established. Systemic anti-inflammatory and immunosuppressive therapy could be an effective treatment, as the LCH itself contains an essential element of inflammation and the symptoms may be mainly inflammatory.

Abstract
Langerhans cell histiocytosis (LCH) is a rare inflammatory myeloid neoplasm arising from the proliferation of pathologic Langerhans cells. LCH has a spectrum of presentations predominantly affecting male pediatric patients. As LCH is a relatively uncommon diagnosis, there is no standard of care for treatment of the disease and treatment is based largely on clinical judgment, lesion characteristics, and symptoms at presentation. Here we present a case of unifocal, isolated orbital LCH in a 19-year-old young man treated initially with surgical resection. Follow-up imaging 2 months later demonstrated significant regrowth of the mass and no other sites of disease. The recurrent orbital disease was treated with stereotactic radiosurgery (SRS) to 7 Gy in one fraction. Near complete resolution of the mass was achieved with no recurrence after 1.5 years of follow-up. SRS for treatment of orbital LCH is a novel treatment not previously described in the literature which may provide benefit in select cases.

Abstract
BACKGROUND Langerhans cell histiocytosis (LCH) is a rare disorder. The treatment options vary depending on how many organs are involved and how extensive the disease is. In this report, a case of LCH with isolated 6th cervical vertebra (C6) collapse was presented. This case was treated with anterior corpectomy and instrumented fusion, followed by local radiotherapy (RT), with a good clinical outcome up to postoperative six months. CASE PRESENTATION This was a 47-year-old female patient with a complaint of neck pain and bilateral shoulder pain for two months before consultation. She was initially treated with analgesics, but the pain was persistent. Further radiological evaluations revealed an osteolytic lesion within the C6 vertebral body with a pathological fracture. Magnetic resonance imaging (MRI) with contrast of the cervical spine revealed diffused hypointense signal changes on the T1-weighted images and hyperintense signal changes on the T2-weighted images in the C6 vertebral body, with significant contrast-enhanced infiltration signals. Furthermore, in positron emission tomography-computed tomography (PET-CT), focal hypermetabolism and abnormal uptake signals were seen only in the C6 vertebral body. The patient underwent an anterior cervical corpectomy with instrumented fusion. The histopathological results confirmed the diagnosis of LCH. The patient reported significant pain relief on postoperative day one. Moreover, she was treated by local RT at postoperative one month. Good clinical outcomes were achieved in the form of no pain and recovery in neck mobility up to postoperative six months. No evidence of recurrence was observed at the final follow-up. CONCLUSIONS This case report describes a treatment option for a solitary C6 collapse with LCH managed by anterior corpectomy and instrumented fusion, followed by local RT, with a good clinical outcome at postoperative six months. More studies are needed to elucidate whether such a treatment strategy is superior to surgery or RT alone.

Abstract
INTRODUCTION Langerhans cell histiocytosis (LCH) is a condition characterized by proliferation of Langerhans cells and wide-range pathologies, ranging from single granulomatous lesions to multi-organ involvement, associated with tissue destruction. LCH pathogenesis remains obscure although association with interleukin (IL)-17A has been reported. We report here a case that illustrates the potential pathogenic role of helper T17 (Th17) cells in LCH-related bone destruction. MATERIALS AND METHODS The patient was a 66-year-old woman. The clinical course included craniectomy and bone mass excision in X-9, diagnosis of LCH confirmed by histopathology, followed by 26-month chemotherapy. In August X, the patient was diagnosed with complete central diabetes insipidus. Symptoms improved after treatment with desmopressin. Pituitary magnetic resonance imaging showed swelling extending from the suprasellar region to the pituitary stalk, suggestive of LCH recurrence. This was followed by chemotherapy combined with mercaptopurine hydrate. RESULTS: Subsequent peripheral blood lymphocyte analysis showed marked increase in activated Th17 cells (CXCR3-CXCR6+ CD4+ T cells). Double staining for CD4 and IL-17 by immunofluorescence of pathological tissue samples obtained during temporal bone mass excision, which confirmed the diagnosis of LCH in X-9, showed areas of combined presence of CD4-positive cells and IL-17-positive cells. Chemotherapy resulted in size reduction of the pituitary lesion and decrease in peripheral blood-activated Th17 cells. CONCLUSIONS We found abundant peripheral blood-activated Th17 cells and high percentages of IL-17-producing cells in osteolytic bone lesions in LCH. This finding, together with the decrease in peripheral blood-activated Th17 cells following chemotherapy, suggests the potential involvement of activated Th17 cells in LCH-related osteolysis.

Abstract
Multiple trials have demonstrated the efficacy of therapies targeting the RAS/MAPK pathway in children with Langerhans cell histiocytosis (LCH), but less is known about the success of this strategy in adults or in LCH that is the result of mutations other than BRAF V600E. A 53-year-old woman who has never smoked presented to our clinic with multisystem, multifocal LCH that resulted from an uncommon BRAF N486_P490del mutation. Low dose, and even intermittent, MEK inhibitor (trametinib) therapy was associated with rapid improvement in almost all of her disease manifestations, including regression of masses in her groin and neck, reduction in seizure frequency and intensity, improvement in white matter lesions on MRI, diabetes insipidus, dyspnea, and cognitive and memory functions. We conclude that MEK inhibitor therapy was effective for BRAF mutation-associated adult multisystem LCH, including CNS manifestations, in this patient.

Abstract
Rare diseases affect less than 1 in 2000 people and are characterized by a serious, chronic, and progressive course. Among the described diseases, a mutation in a single gene caused mastocytosis, thrombotic thrombocytopenic purpura, Gaucher disease, and paroxysmal nocturnal hemoglobinuria (KIT, ADAMTS13, GBA1, and PIG-A genes, respectively). In Castleman disease, improper ETS1, PTPN6, TGFBR2, DNMT3A, and PDGFRB genes cause the appearance of symptoms. In histiocytosis, several mutation variants are described: BRAF, MAP2K1, MAP3K1, ARAF, ERBB3, NRAS, KRAS, PICK1, PIK3R2, and PIK3CA. Genes like HPLH1, PRF1, UNC13D, STX11, STXBP2, SH2D1A, BIRC4, ITK, CD27, MAGT1, LYST, AP3B1, and RAB27A are possible reasons for hemophagocytic lymphohistiocytosis. Among novel molecular medicines, tyrosine kinase inhibitors, mTOR inhibitors, BRAF inhibitors, interleukin 1 or 6 receptor antagonists, monoclonal antibodies, and JAK inhibitors are examples of drugs expanding therapeutic possibilities. An explanation of the molecular basis of rare diseases might lead to a better understanding of the pathogenesis and prognosis of the disease and may allow for the development of new molecularly targeted therapies.

Detection of Immune Microenvironment Changes and Immune-Related Regulators in Langerhans Cell Histiocytosis Bone Metastasis. BIOMED RESEARCH INTERNATIONAL 2023; 2023:1447435.

Abstract
The inflammation/immune response pathway is considered a key contributor to the development of Langerhans cell histiocytosis (LCH) bone metastasis. However, the dynamic changes in the immune microenvironment of LCH bone metastasis and critical regulators are still unclear. Expression profiling by arrays of GSE16395, GSE35340, and GSE122476 was applied to detect the immune microenvironment changes in the development of LCH bone metastasis. The single-cell high-throughput sequencing of GSE133704, involved in LCH bone lesions, was analyzed. The online database Metascape and gene set variation analysis (GSVA) algorithms were used to detect the gene function of Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG). The protein-protein interaction (PPI) network of hub regulators was constructed by the STRING database. In these results, key immune cells, such as Tem cells, NK T cells, CD8(+) T cells, and Th1 cells, were identified in LCH bone metastasis. These genes, which include LAG3, TSPAN5, LPAR5, VEGFA, CXCL16, CD74, and MARCKS, may significantly correlate with the cellular infiltration of B cells, aDCs, pDCs, cytotoxic cells, T cells, CD8+ T cells, T helper cells, and Tcm cells. In conclusion, our study constructed an atlas of the immune microenvironment of LCH bone metastasis. Genes including LAG3, TSPAN5, LPAR5, VEGFA, CXCL16, CD74, and MARCKS may be involved in the development of LCH bone metastasis. The hub gene-immune cell interactive map may be a potential prognostic biomarker for the progression of LCH bone metastasis and synergetic targets for immunotherapy in LCH patients.

Abstract
ABSTRACT We describe a case of Langerhans cell histiocytosis involving the bilateral pleura on FDG PET/CT. Multiple pleural nodules were detected by CT in a 38-year-old woman with chest pain and night sweats. Malignant tumors were suspected. PET/CT showed abnormal FDG uptake in those pleural lesions. No other abnormal foci were seen in the rest of the whole body. A primary pleural disease was considered. Then the histopathologic findings after biopsy confirmed the diagnosis of Langerhans cell histiocytosis.

Optimal timing of liver transplantation for liver cirrhosis caused by sclerosing cholangitis in a patient with Langerhans cell histiocytosis: a case report. Int J Hematol 2022; 117:759-764.

Abstract
Liver cirrhosis due to secondary sclerosing cholangitis caused by Langerhans cell histiocytosis (LCH) has a poor prognosis, and liver transplantation is the definitive treatment. However, the optimal timing has not been established. We report a 2-year-old girl with LCH-related liver cirrhosis who successfully underwent liver transplantation before progressing to severe liver dysfunction. Physical examination revealed a tumor on her palate. Biopsy was performed, and a diagnosis of LCH was established, together with hepatomegaly, splenomegaly, and rashes. Percutaneous liver biopsy before treatment revealed extreme fibrosis and absence of LCH cells. After beginning chemotherapy, she experienced several delays in treatment and dose reductions because of unacceptable bone marrow suppression, worsening liver dysfunction, and cholangitis. However, tumor shrinkage was observed in both magnetic resonance imaging and BRAF V600E mutant allele titers in her plasma. Given the good treatment response, liver transplantation was conducted. The postoperative course was uneventful, and chemotherapy was resumed 34 days after liver transplantation. Subsequent maintenance treatment was completed with no severe adverse effects. To prevent perioperative complications due to exacerbation of liver dysfunction and possible discontinuation of chemotherapy, liver transplantation should be considered before development of end-stage liver failure, provided that the original disease is well controlled.

Abstract
BACKGROUND Langerhans cell histiocytosis (LCH) is a rare condition caused by a neoplastic proliferation of myeloid cells. It can present as a single-system or multi-system disorder. Worse prognosis is associated with the hematopoietic system (spleen, liver, bone marrow), which is routinely observed in multi-system disease. Because of the varied presentation of this disorder, diagnosis can be difficult, and therefore suitable treatment can be delayed. CASE REPORT We report a case of hepatic LCH in a 51-year-old man who presented with epigastric abdominal pain, with imaging demonstrating a hepatic nodule. A low ejection fraction on hepatobiliary iminodiacetic acid scan suggested chronic cholecystitis. Therefore, the patient underwent a cholecystectomy for biliary dyskinesia, in which liver nodules were noted, and biopsies were taken. The biopsies demonstrated characteristic findings of LCH along with positive immunohistochemical markers and negative BRAF V600E mutation. Radiologic and pathologic findings were consistent with LCH within the liver, associated with bile duct injury and mild biliary obstruction. The patient was placed on a cladribine regimen. His abdominal pain improved. CONCLUSIONS LCH limited to the liver is uncommon and can appear as chronic biliary disease, as was suspected in this case. Despite the poor prognosis of hematopoietic LCH, early recognition can lead to better outcome and chemotherapy susceptibility. This patient was most likely in the first stage of liver LCH, given his presentation, which could have aided his response to chemotherapy. The lack of BRAF V600E mutation could have contributed to a positive prognosis and more possibilities for treatment.

Abstract
Langerhans cell histiocytosis (LCH) is a rare inflammatory myeloid neoplasia with a broad spectrum of clinical manifestations. The activation of the MAP kinase pathway plays an integral role in its pathogenesis with genetic alterations found in the majority of cases that most frequently involve a somatic mutation of the oncogenic BRAFV600E variant. In this study we investigated the prevalence of the BRAFV600E mutation and its clinical relevance in adult Greek patients with LCH. Among 37 patients studied, the BRAFV600E mutation was identified in 12 out of 31 (38.7%), whereas in six patients (19.3%) the results were in conclusive. The presence of the mutation did not correlate with age at diagnosis, organ involvement, disease extent, response to initial treatment, development of diabetes insipidus and relapse risk. In our series the prevalence of the BRAFV600E mutation is at the lower range of the relative percentage found in children, but in line to that obtained in previous studies of adult patients with LCH that have found an up to 50% prevalence of the BRAFV600E mutation in these patients. Further studies with a larger number of adults are needed to identify the exact prevalence of mutations in the RAS-RAF-MEK-ERK pathway and their role on clinical parameters and disease outcomes.Supplemental data for this article is available online at https://doi.org/10.1080/08880018.2022.2029988 .

Abstract
Background Langerhans cell histiocytosis (LCH) is a myeloid dendritic cell disorder frequently affecting children more than adults. The presentation of LCH varies with age, however, the clinical characteristics and genetic profiles of adolescent LCH remain elusive. To address the knowledge gap, we performed a single-centre retrospective study of 36 adolescent LCH patients aged between 14 and 17 years at Peking Union Medical College Hospital. Results At the time of diagnosis, 10 patients were classified as unifocal single system LCH (27.8%), 2 patients had pulmonary single system LCH (5.6%), 5 patients had multifocal single system LCH with bone involvement (13.9%), and 19 patients had multisystem LCH (52.8%). The most prevalent involvement in multisystem patients was the pituitary gland (78.9%), followed by the bone (42.1%), lung (42.1%), and lymph nodes (42.1%). Eight (42.1%) patients had risk organ involvement. BRAFN486_P490 was detected in 50% of patients who underwent next generation sequencing, and BRAFV600E was detected in one patient. Chemotherapies were the first line treatment in 24 patients. One patient died and thirteen patients relapsed during the follow-up. The estimated 5-year OS rate and EFS rate were 94.7% and 59.0%, respectively. Conclusions In this study, we report a large series of adolescent LCH patients. The clinical characteristics of adolescent LCH patients may be close to adult LCH. Compared with pediatric cases, adolescent LCH tends to have more pituitary lesions and pulmonary involvement, fewer skin and hematopoietic involvement, a higher frequency of BRAF deletion mutation, and a lower frequency of BRAFV600E mutation.

Abstract
Langerhans cell histiocytosis (LCH) is a clonal histiocytic neoplasm with various clinical manifestations and heterogeneous prognoses. No standard therapy is available for recurrent/refractory LCH patients. This single-center, single-arm, phase 2 study enrolled 32 patients diagnosed with recurrent/refractory LCH. The TCD regimen (thalidomide 100 mg daily, cyclophosphamide 300 mg/m2 Day 1, 8, 15, and dexamethasone 40 mg Day 1, 8, 15, 22 every 4 weeks) was administered for 12 cycles and thalidomide alone as maintenance for 12 months. The primary endpoint was event-free survival (EFS). Events were defined as progression during or after TCD therapy or death from any cause. After a median follow-up of 22 months (range 5-24 months), no patient died of all causes. The overall response rate was 87.5%, including 18 patients (56.3%) achieving complete remission and 10 patients (31.3%) as partial remission. The estimated 24-month EFS was 64.0%. Patients with risk organ involvement had similar EFS compared to patients without risk organ involvement (P = 0.38). The common toxicities of TCD regimen include grade 1-2 neutropenia (18.8%), grade 1-2 constipation (12.5%), grade 1-2 tiredness (9.4%) and grade 2 peripheral neuropathy (12.5%). Oral thalidomide, cyclophosphamide and dexamethasone are effective and safe regimen for recurrent/refractory LCH patients, particularly for patients with risk organ involvement.

Abstract
Langerhans Cell Histiocytosis is a rare disorder characterized by an abnormal proliferation of Langerhans cells in one or multiple organs. It rarely presents with a central vestibular involvement. We report a case of a multisystem Langerhans Cell Histiocytosis with mucosal, hepatic, and neurological involvement, presenting with dizziness and balance disorders. A 39-year-old woman with a histopathologically confirmed mucosal palatal Langerhans Cell Histiocytosis presented with a history of dizziness for a year. Vestibular examination revealed a saccadic eyes pursuit, an up beating spontaneous nystagmus, a bilateral gaze nystagmus and a prolonged positional nystagmus, in the supine roll test. Pure tone audiometry showed a slight left sensorineural hearing loss at the 8000 Hz frequency. Computed tomography (CT) scan showed a bilateral maxillary sinus fullness and a peripheral osteosclerosis of the surrounding bony walls. Hepatic magnetic resonance imaging (MRI) showed a typical hepatic involvement with a hepatomegaly with countless cysts. Temporal bone CT scan and MRI were normal. Cerebral MRI showed an hyperintense nodular signal at T2 FLAIR weighted images lateral to the right pons, at the level of the left middle cerebellar peduncle and at the left mesencephalon. Balance disorders can rarely present a sign of a degenerative neurological cerebellar involvement. Such a rare manifestation can present in different neurological disorders such as Langerhans' cell Histiocytosis.

Abstract
Langerhans cell histiocytosis (LCH) is a rare disease characterized by clonal expansion of CD1a+/CD207+ cells in lesions. The most frequent sites involved are bone and, less commonly, lymph nodes, lungs, and skin. The thymus or heart is rarely involved with LCH. In this case, we present a 73-year-old woman with a mediastinal mass. Histopathology after thymectomy identified this mass as type AB thymoma; notably, subsequent immunohistochemical tests showed lesions of LCH scattered in the region of thymoma. 18-Fluorodeoxyglucose PET/CT (18-FDG-PET/CT) was performed to make an overall assessment of the extent of this disease, which demonstrated suspicious cardiac involvement of LCH. This report highlights the importance of differentiating abnormalities of the thymus or mediastinal mass from LCH and the necessity of comprehensive evaluation for patients with LCH.

Abstract
Langerhans cell histiocytosis (LCH) is an uncommon clonal proliferation of myeloid progenitor cells, it is especially rare in adults. We present a case of multi-system LCH in a 53-year-old woman, the sole symptom of which was prolonged, non-resolving hip pain for 18 months prior to the diagnosis. Initial evaluation included imaging studies aimed at identifying a presumed local etiology. X-ray demonstrated non-specific arthritic changes on the left femur. Computed tomography (CT) and magnetic resonance imaging (MRI) scans identified a lytic lesion at the same location, warranting a systemic workup. After non-invasive investigations failed to reveal the underlying etiology, a biopsy was performed, revealing cores of Langerhans cells that stained positive for both CD1a and langerin. These findings verified the surprising, uncommon diagnosis of LCH. A comprehensive workup was conducted in order to determine the extent of the disease and its molecular nature - revealing a BRAFV600E-positive, high-risk, multi-system LCH with skeletal, lung and liver involvement.

Abstract
OBJECTIVES Pulmonary Langerhans cell histiocytosis (PLCH) is a clonal disease, characterized by proliferation of Langerhans cells that derived from bone marrow infiltrating the lungs and other organs. Due to the rarity of the disease, the current understanding of the disease is insufficient, often misdiagnosed or missed diagnosis. This study aims to raise clinicians' awareness for this disease via summarizing the clinical characteristics, imaging features, and treatment of PLCH. METHODS We retrospectively analyzed clinical and follow-up data of 15 hospitalized cases of PLCH from September 2012 to June 2021 in the Second Xiangya Hospital of Central South University. RESULTS The age of 15 patients (9 men and 6 women, with a sex ratio of 3 to 2) was 21-52 (median 33) years. Among them, 8 had a history of smoking and 5 suffered spontaneous pneumothorax during disease course. There were 3 patients with single system PLCH and 12 patients with multi-system PLCH, including 7 patients with pituitary involvement, 7 patients with lymph node involvement, 6 patients with bone involvement, 5 patients with liver involvement, 2 patients with skin involvement, 2 patients with thyroid involvement, and 1 patients with thymus involvement. The clinical manifestations were varied but non-specific. Respiratory symptoms mainly included dry cough, sputum expectoration, chest pain, etc. Constitutional symptoms included fever and weight loss. Patients with multi-system involvement experienced symptoms such as polyuria-polydipsia, bone pain, and skin rash. All patients were confirmed by pathology, including 6 by lung biopsy, 3 by bone biopsy, 2 by lymph node biopsy, and 4 by liver, skin, suprasternal fossa tumor, or pituitary stalk biopsy. The most common CT findings from this cohort of patients were nodules and/or cysts and nodular and cystic shadows were found in 7 patients. Three patients presented simple multiple cystic shadows, 3 patients presented multiple nodules, and 2 patients presented with single nodules and mass shadows. Pulmonary function tests were performed in 4 patients, ventilation dysfunction was showed in 2 patients at the first visit. Pulmonary diffusion function tests were performed in 4 patients and showed a decrease in 3 patients. Smoking cessation was recommended to PLCH patients with smoking history. Ten patients received chemotherapy while 2 patients received oral glucocorticoid therapy. Among the 11 patients with the long-term follow-up, 9 were in stable condition. CONCLUSIONS PLCH is a neoplastic disease closely related to smoking. The clinical manifestations and laboratory examination are not specific. Pneumothorax could be the first symptom which is very suggestive of the disease. Definitive diagnosis relies on histology. There is no unified treatment plan for PLCH, and individualized treatment should be carried out according to organ involvement. Early smoking cessation is essential. Chemotherapy is the main treatment for rapidly progressing PLCH involved multiple organs. All diagnosed patients can be considered for the detection of BRAFV600E gene and relevant targeted therapies have been implemented recently.

Abstract
Langerhans cell histiocytosis (LCH) refers to a group of diseases of unknown etiology, typically discovered in childhood, characterized by the accumulation of Langerhans cells (white blood cells with large cell nuclei that may contain cytoplasmic histiocytosis X bodies) involving one or more organ systems, including bones, lungs, pituitary gland, skin, lymph nodes, and liver. This disease is also known as histiocytosis X or eosinophilic granuloma. Pulmonary LCH is common (identified in 40% of LCH patients) and may be isolated to the lung or involve other organs. Although LCH is characterized by clonal cell proliferation, adult LCH is considered likely to represent the manifestation of an aberrant immune response to an unspecified antigenic stimulus rather than a manifestation of tumor proliferation. We report a very complicated clinical case of LCH, with multiple organ damage that received a variety of different diagnoses. An LCH diagnosis was confirmed based on postoperative spinal cord pathology results and immunohistochemistry examinations. This case report highlights the clinical, laboratory, and imaging signs observed in this case that should be noted to help doctors more quickly recognize, diagnose, and treat similar cases.

Abstract
Langerhans cell histiocytosis (LCH) is a rare inflammatory neoplasia in which somatic mutations in components of the MAPK/ERK pathway have been identified. Osseous involvement is evident in approximately 80% of all patients and may present as a single osteolytic lesion, as a multi-ostotic single system disease or as part of multisystem disease. Both exogenous, such as treatment with glucocorticoids, and endogenous parameters, such as anterior pituitary hormone deficiencies and inflammatory cytokines, may severely affect bone metabolism in LCH. Computed tomography (CT) or magnetic resonance imaging (MRI) are usually required to precisely assess the degree of bone involvement; 18F-fluorodeoxyglucose (FDG) positron emission tomography-CT can both detect otherwise undetectable LCH lesions and differentiate metabolically active from inactive or resolved disease, while concomitantly being useful in the assessment of treatment response. Treatment of skeletal involvement may vary depending on location, extent, size, and symptoms of the disease from close observation and follow-up in unifocal single-system disease to chemotherapy and gene-targeted treatment in cases with multisystem involvement. In any case of osseous involvement, bisphosphonates might be considered as a treatment option especially if pain relief is urgently needed. Finally, a patient-specific approach is suggested to avoid unnecessary extensive surgical interventions and/or medical overtreatment.

Abstract
Adult Langerhans cell histiocytosis (LCH) remains poorly defined. We retrospectively studied 266 newly diagnosed LCH patients to understand the clinical presentation, treatment, and prognosis of adult LCH. The median age at diagnosis was 32 years (range, 18-79 years). At the time of diagnosis, 40 patients had single lesions within a single system, 18 patients had single pulmonary LCH, 26 patients had multiple lesions within a single system (SS-m), and 182 patients had multisystem disease (MS). The most common organ involved in MS patients was the bone (69.8%), followed by the pituitary (61.5%) and lung (61.0%). BRAFV600E , BRAF deletion, and MAP2K1 mutation were detected in 38.8%, 25.4%, and 19.4% patients, respectively. BRAF deletion was found more common in patients with MS LCH compared to single-system LCH (38.5% vs 7.1%, p = .004), also in patients with liver involvement (69.2% vs 14.3%, p < .001). The estimated 3-year overall survival (OS) and event-free survival (EFS) rates were 94.4% and 54.7%, respectively, in SS-m and MS LCH. Multivariate Cox regression showed that involvement of the liver or spleen at baseline predicted poor EFS and receiving cytarabine-based therapy as a first-line treatment and age older than 30 years at diagnosis predicted favorable EFS. The involvement of risk organs and age older than 50 years predicted poor OS, and receiving cytarabine-based therapy predicted favorable OS. Therefore, BRAF deletion was correlated with MS LCH, particularly those with liver involvement. Liver or spleen involvement at baseline indicates a poor prognosis, and a cytarabine-based regimen could be considered as first-line treatment for adult LCH patients.

Abstract
Background Langerhans cell histiocytosis (LCH) is a rare condition that has a variety of clinical manifestations. But LCH in children localized only in the hepatobiliary system is unusual. Case presentation. Here we reported a rare case of a 2-year-old boy who was serendipitously found to have elevated liver enzymes while undergoing treatment of a perianal abscess. After a period of earlier conservative treatment in another hospital, the perianal abscess had resolved but the levels of liver enzymes were still rising slowly. The child was then referred to our institution for a definitive diagnosis. After laboratory tests, imaging and pathological examinations, a diagnosis of liver cirrhosis and sclerosing cholangitis was established, although the cause was unclear. Subsequently, living-donor liver transplantation was performed due to deterioration in liver function. Following successful liver transplantation, a diagnosis of LCH localized only within the hepatobiliary system was finally confirmed, based on additional pathological and imaging investigation. Additionally, the BRAF V600E mutation in this patient was also confirmed. The child has now recovered without evidence of LCH recurrence. Conclusions LCH localized only within the hepatobiliary system is unusual. The presence of unexplainable sclerosing cholangitis and liver cirrhosis in any child should raise the suspicion of LCH.

Abstract
Langerhans cell histiocytosis (LCH) is a rare disease characterized by the clonal accumulation and/or proliferation of specific dendritic cells resembling normal epidermal Langerhans cells (LCs). Clinical manifestations are variable, depending on the affected tissues or organs, however, LCH with elevated serum IgG4 has not been reported. Herein, we reported a 26-year-old Chinese female multi-system LCH (MS-LCH) who first presented with central diabetes insipidus (CDI), accompanied by panhypopituitarism and hepatic dysfunction. Diagnostic investigations were strongly suspicious of IgG4-RD because of elevated serum IgG4 levels during the process. Furtherly, thyroid and lymph node involvement and biopsy led to the diagnosis of MS-LCH; the strongly positive staining of CD1a, S100, CD207 (langerin), and Ki67 was found. Moreover, after systemic treatment with five cycles of chemotherapy, many lesions were greatly improved. Since both LCH and IgG4-RD are orphan diseases that can affect any organ, the differential diagnosis is challenging, especially when LCH is associated with unexplained serum IgG4 elevation. In this article, the case of a young woman suffering from MS-LCH that affected organs including the pituitary, thyroid, lymph node, and liver was summarized, and relevant literature was reviewed to better equip the diagnosis and treatment in its early stages.

Abstract
BACKGROUND Langerhans cell histiocytosis (LCH) is a rare disease caused by the clonal expansion of CD1a+/CD207+ LCH cells. The thyroid involvement in LCH has mostly been described in case reports. METHODS We retrospectively evaluated the clinical characteristics, diagnosis, and treatment of 27 children and adult patients with thyroid LCH in our center between 2010 and 2021. RESULTS The incidence of thyroid LCH was 14.00% (7/50) in children and 10.10% (20/198) in adults, respectively. Among patients with thyroid involvement, 81.5% presented with diabetes insipidus (DI) as the first symptom, and 51.9% complained of neck swelling or mass. Children and adults with thyroid LCH had higher frequencies of the hypothalamic-pituitary axis (HPA) (children: 100% vs. 62.8%, P=0.05; adult: 95% vs. 42.1%, P<0.001), the lung (children: 85.7% vs. 25.6%, P=0.004; adult: 70% vs. 50.6%, P=0.099), and a lower frequency of bone (children: 14.3% vs. 55.8%, P=0.049; adult: 45% vs. 73.6%, P=0.008) involvement than patients without thyroid involvement. Patients with thyroid LCH had a higher frequency of primary hypothyroidism and a lower frequency of euthyroidism than patients without it. The two major types of ultrasound imaging were diffuse (55%) and nodular type (45%). The standardized uptake value of thyroid on 18-F-fluorodeoxyglucose positron emission tomography/computed tomography was 5.3-12.8. The diagnoses were confirmed using thyroid aspiration (54.5%) or surgery (45.5%). In addition, thyroid LCH combined with papillary thyroid carcinoma was not rare (2/27). CONCLUSION Thyroid involvement in LCH is not rare. Furthermore, identifying thyroid involvement can facilitate the pathological diagnosis of LCH. Therefore, the possibility of thyroid LCH should be fully investigated in patients with DI, primary hypothyroidism, abnormal thyroid ultrasound results, and multi-system disease. In addition, thyroid aspiration can confirm suspected thyroid LCH. Finally, special attention should be paid to evaluating HPA and pulmonary involvement in thyroid LCH.

Abstract
Introduction: Langerhans cell histiocytosis (LCH) is an abnormal clonal proliferation of Langerhans cells secondary to immune process, mutation of oncogene or genetic predispositions. It preferentially affects bone, lung and skin. The incidence is 2–6 cases per million per year. Prognosis is variable and depends on number and location of lesions, and impact of the initial treatment. Oral lesions may be the first sign of LCH as illustrated by the present case. Observation: A 24-year-old male consulted first for severe gingival inflammation, teeth mobilities and alveolar bone loss with a suspicion of LCH. A pulmonary involvement was secondarily revealed by tomodensitometry. Histological examination, from gingival biopsy, confirmed the diagnostic of LCH, showing cells positive for the anti-CD1A antibody. The patient was managed by oral surgery and chemotherapy approaches. Alveolar bone loss significantly reduced. But 2 years and a half after the diagnosis, a recurrence was noted and managed by surgical approach. After a three-year follow-up, no recurrence was noted. Conclusion: Oral lesions can be inaugural manifestations of LCH. The dentist has an essential role in the early detection of these lesions.

Abstract
It is unusual that an unexpected mass is encountered within a hernia sac. This report describes a patient diagnosed with Langerhans cell histiocytosis (LCH) after surgery for an inguinal hernia. A 64-year-old male patient presented with inguinal mass over a 1-year period. Direct inguinal hernias were found in both sides, and enlarged lymph nodes were found in both hernia sacs. Laparoscopic totally extraperitoneal repair was done, and one enlarged lymph node within inguinal hernia sac was excised for diagnostic purposes. Microscopic findings showed the distinctive cytologic features of Langerhans cells and immunohistochemical staining are positive for CD1a and S-100. LCH is a rare disorder, and the involvement of the lymph nodes with no other sites of disease is uncommon. To the best of our knowledge, this is the first report of LCH within an inguinal hernia sac. Multidisciplinary approach should be considered to provide better detection and treatment.

Abstract
Langheransian cell histiocytosis (LCH) is a rare pathology characterized by the proliferation of CD1+ and Langerin+ cells. It can affect all ages, with an estimated prevalence of one to two cases/100,000 habitants. The involvement is often multi-visceral; however, isolated cutaneous involvement can be found in 40% of cases with very variable manifestations. We report the case of 45-year-old women followed for non-insulin-dependent diabetes and primary hyperparathyroidism suffering from isolated and refractory cutaneous histiocytosis.

Abstract
Langerhans cell histiocytosis (LCH) is a rare systemic disease caused by proliferation of mature histiocytes; its association to histiocyto fibroma is rarely reported. It rarely affects adults. We report a case of systemic LCH, in an adult patient with osteolytic lesion causing a fistula between the left nasal cavity and hard palate, involving the bone, lung, lymph node and associated to multiple histiocyto fibroma. The patient was operating for a fistula, and he was treated by chemotherapy and corticosteroids. Langerhans´ cell histiocytosis is a rare case, especially in adult patient. The diagnosis was based on histological and immunohistochemical analyses. This patient was treated by steroids and chemotherapy.

Characterization of PD-1/PD-L1 immune checkpoint expression in the pathogenesis of musculoskeletal Langerhans cell histiocytosis: A retrospective study. Medicine (Baltimore) 2021; 100:e27650. [PMID: 34713856 PMCID: PMC8556058 DOI: 10.1097/md.0000000000027650] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/07/2021] [Accepted: 10/12/2021] [Indexed: 01/05/2023] Open
Abstract
Recent data suggest that programmed cell death -1 (PD-1) and programmed cell death ligand-1 (PD-L1) are involved in the pathogenesis of Langerhans cell histiocytoma (LCH); however, their contributions are not well established. Also, the involvement of PD-1/PD-L1 molecules in musculoskeletal LCH remains particularly unclear. The current study aims to characterize the involvement of PD-1/PD-L1 immune checkpoint system in the pathogenesis of musculoskeletal LCH. PD-1/PD-L1 expression was evaluated in 6 patients, 3 men and 3 women with a mean age of 13.5 years, with musculoskeletal LCH who were treated at Kindai University Hospital and Osaka Women's and Children's Hospital between November 2005 and December 2020. The median follow-up period for all patients with musculoskeletal LCH was 41 months. We surveyed symptoms, number of lesions, treatment modality, and outcomes. Immunostaining for CD4, CD8, PD-1, and PD-L1 was also performed on pathological specimens obtained by biopsy. Multiple lesions were observed in 5 cases, and a single lesion was observed in 1 case. The chief complaint in 5 cases was pain. Four patients underwent spontaneous regression. The other 2 patients received chemotherapy. The outcomes included continuous disease-free (n = 5) and alive with the disease (n = 1). The CD4-, CD8-, PD-1-, and PD-L1-positive rates among all specimens were 100%, 100%, 16.6%, and 83.3%, respectively. The CD4/PD-L1, CD8/PD-L1, and PD-1/PD-L1 positive rates in all the specimens were 83.3%, 83.3%, and 16.6%, respectively. We believe that the PD-1/PD-L1 immune checkpoint molecules may play some role in the microenvironment of musculoskeletal LCH.
