Langerhans cell histiocytosis (LCH) is a rare histiocytic neoplasm. The clinical presentation and the disease extension are variable. LCH may involve single site, multiple sites within system, or systems. Gastrointestinal tract involvement most often observed in children with multisystem disease. Adult patients gastrointestinal extremely rare, only few cases have been reported. We present 45-ye...
CT: computed tomography LCH: Langerhans cell histiocytosis PPAR-g: peroxisome proliferatoreactivated receptor-g INTRODUCTION The etiology of Langerhans cell histiocytosis (LCH), a mix between immune dysregulation, inflammation, and malignancy, remains unclear. In half of the patients, an oncogenic BRAF mutation is found. Because of the diversity of symptoms, the diagnosis of LCH, as defined by ...
Interleukin-17 (IL-17A) is a pro-inflammatory cytokine that has recently been implicated in pathogenesis of Langerhans Cell Histiocytosis (LCH), a potentially fatal disease characterized by lesions including CD207+ (langerin +) histiocytes. However, in this study we were unable to identify IL-17A gene expression in Langerhans cell lesions, and plasma levels of IL-17A did not correlate with dise...
Introduction: Langerhans cell histiocytosis (LCH) refers to a group of rare reticuloendothelial system disorders and it occurs most often in young adults and children. A 57-year-old edentulous female patient who complained of dull pain in the posterior region of the mandible referred to the dental office, with a complaint of dull pain in the posterior region of the mandible. The lesion was diag...
Block 6 Level 9, Dermatology Unit, Singapore General Hospital, Outram Road, 169608, Singapore Langerhans cell histiocytosis (LCH) is a proliferative histiocytic disorder of unknown cause characterized by the accumulation of Langerhan cells in various tissues. Typically a disorder of childhood, features of this disease have been well documented in children but remain ambiguous and poorly documen...
Langerhans cell histiocytosis (LCH), is a rare disorder, clinically presents with heterogeneous manifestations, and has an unpredictable outcome. Commonly seen in infancy or early childhood, the disorder is characterized by proliferation of abnormal and clonal Langerhans cell in skin, bone, lymph nodes, lungs, liver, spleen, and bone marrow. Occurrence of LCH in adults is rare. Here, we report ...
UNLABELLED Histiocytic neoplasms are clonal, hematopoietic disorders characterized by an accumulation of abnormal, monocyte-derived dendritic cells or macrophages in Langerhans cell histiocytosis (LCH) and non-Langerhans cell histiocytosis (non-LCH), respectively. The discovery of BRAF(V600E) mutations in approximately 50% of these patients provided the first molecular therapeutic target in his...
Corresponding author: Wen LI; Tel: +86-13601858540; Fax: +86-21-63520020; E-mail: [email protected] Langerhans cell histiocytosis (LCH), also known as Histiocytosis X, is characterized by an organ-specific infiltration of cells with many morphological features and immunohistochemical markers of Langerhans cells. Clinically, LCH ranges from self-healing lesions to a multisystem involvement with ...
A three and half year old boy with Langerhans' cell histiocytosis (LCH) formerly called as eosinophilic granuloma has been presented along with the desired treatment plan.
Langerhans cell histiocytosis (LCH) is a rare disorder characterised by increased production of Langerhans-type histiocytes. It more common in the pediatric age group with predilection for osseous involvement, though any organ may be involved. A 10-year male child was brought to neurosurgical clinic slow growing painful tender mass on head. Initial attempt biopsy lesion failed due excessive ble...
