Abstract
BACKGROUND Langerhans cell histiocytosis (LCH) is a rare disorder characterized by abnormal proliferation and infiltration of histiocytic cells. METHODS This review focused on the main aspects associated with LCH. RESULTS LCH can involve single or multiple organs and systems, with bone and skin being the most commonly affected sites. Regarding skeletal manifestations, the jawbones are involved in about 20%-30% of all cases. Such lesions may present as unilocular or multilocular images mainly affecting the posterior mandible. Oral soft tissue lesions may also occur, with the gingiva and hard palate being the most frequently affected sites. CONCLUSION The diagnosis and management of LCH are challenging, requiring a multidisciplinary approach, with dentists playing a central role since oral manifestations can be the first sign of the condition.

Abstract
AbstractLangerhans cell histiocytosis (LCH) is an uncommon hematological disorder affecting infants and young children. LCH is a rare disorder of the reticuloendothelial system associated with proliferation of Langerhans cells and mature eosinophils. LCH can involve any bone, but the most common are pelvis, ribs, skull, long bones, vertebra, and facial bones. In the skull, frontal and parietal bones are commonly involved followed by the jaws, where mandible is more commonly affected than the maxilla. In this article, we report a case of LCH in a 5-year-old child involving the mandible. Swelling of one side of the face and aggressive periosteal reaction led to the diagnosis of monostotic LCH. The manuscript also summarizes the results of a literature search in PubMed of reported cases of LCH over the past 10 years.

Abstract
Langerhans cell histiocytosis (LCH), previously known as histiocytosis X, is an uncommon hematological disorder affecting infants and young children. It is the condition characterized by uncontrolled stimulation and proliferation of normal antigen presenting cells, Langerhans cells. Because of its relatively low incidence, limited data are available regarding the epidemiology of LCH, with estimation of 2–5 cases per million inhabitants per year. The purpose of this report is to describe the case of LCH in the 3-year-old male child with multiple focal involvements of bones and to discuss clinical, radiological and histopathological features of LCH and role of the dental surgeon in diagnosing and managing such lesions.

Abstract
Nucleoside, nucleotide, and base analogs have been in the clinic for decades to treat both viral pathogens and neoplasms. More than 20% of patients on anticancer chemotherapy have been treated with one or more of these analogs. This review focuses on the chemical synthesis and biology of anticancer nucleoside, nucleotide, and base analogs that are FDA-approved and in clinical development since 2000. We highlight the cellular biology and clinical biology of analogs, drug resistance mechanisms, and compound specificity towards different cancer types. Furthermore, we explore analog syntheses as well as improved and scale-up syntheses. We conclude with a discussion on what might lie ahead for medicinal chemists, biologists, and physicians as they try to improve analog efficacy through prodrug strategies and drug combinations.

Abstract
Background: Langerhans cell histiocytosis (LCH) is a rare disease involving clonal proliferation of cells with characteristics similar to bone marrow-derived Langerhans cells. The case of a young woman, affected by Turner syndrome and a solitary intraparenchymal LCH associated with an osteolytic lesion of the overlying skull, is presented. Case Description: The patient, with an insidious history of headache and a growing soft mass in the left frontal region, presented with a sudden generalized tonic-clonic epileptic seizure. Neuroradiological investigations showed an osteolytic lesion of the left frontal bone and an underlying brain lesion associated with recent signs of bleeding. The patient was operated on with a complete removal of the lesion. The postoperative course was uneventful. Conclusions: The clinical, neuroradiological, and intraoperative findings are presented, along with a review of the literature. Although rare, LCH should be considered in the differential diagnosis when a scalp lesion occurs with a progressive growing.

Abstract
Langerhans cell histiocytosis (LCH) is a group of idiopathic disorders characterized by proliferation of bone marrow derived Langerhans cells and mature eosinophils. Their clinical features simulate common oral findings such as gingival enlargement, oral ulcers, and mobility of teeth, along with nonspecific radiographic features; hence, diagnosing such lesions becomes difficult for the oral physicians. These lesions are commonly seen in childhood; however, we are reporting a case of LCH in 29-year-old adult male. A provisional diagnosis of giant cell granuloma was considered based on history and examination, although the lesion was histologically proven to be LCH and was confirmed with immunohistochemical staining of S100 protein and CD1a antigen. The purpose of this paper is to enhance the understanding of diverse, nonpathognomical oral presentation of LCH that is easily misdiagnosed and overlooked by dentist.

Abstract
Langerhans cell histiocytosis (LCH) is a proliferative disease of histiocyte-like cells, with a wide range of clinical presentations that vary from a solitary lesion to more severe multifocal or disseminated lesions. The disease can affect any age group; however, the peak incidence rate is in infants aged between 1 and 3 years-old. Diagnosis of LCH should be based on the synthetical analysis of clinical presentations, in addition to features of imaging and histopathology. Although certain cases regress spontaneously, other patients require systemic chemotherapy together with the administration of steroids. The present study reports the case of an infant with LDH with multisystem involvement, including that of the bone, skin, orbit, spleen and lungs. The patient received chemotherapy and obtained rapid improvement in the involved systems. A total of 2.5 years after completion of the therapy, the patient still remains in follow-up and no evidence of active disease has been noted.
