INTRODUCTION: Chronic recurrent multifocal osteomyelitis (CRMO) is a rare autoinflammatory condition. The clinical picture consists of sterile osteomyelitis, typically with multiple-site lesions in the metaphysis of long bones and not uncommonly, symmetrical bone involvement. It is a poorly understood entity, whose prognosis, etiology and ideal treatment are still controversial. The authors report a case of unifocal presentation with an atypical location. CASE REPORT: A previously healthy 12-year-old Caucasian girl came to our institution due to progressive pain on her left thigh for the previous 3 months...

Polyostotic sclerosing histiocytosis, also known as Erdheim-Chester disease (ECD), is a rare form of non-Langerhans histiocytosis. ECD has wide clinical spectrums which mainly affect skeletal, neurological, dermatological, retroperitoneal, cardiac, and pulmonary manifestations. Here we describe a case of ECD in a 45-year-old female who presented initially with bilateral knee pain and homonymous superior quadrantanopia progressed to ophthalmoplegia and complete visual loss of the left eye over a period of one year...

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...

Many patients with histiocytic disorders such as Langerhans cell histiocytosis (LCH) or Erdheim-Chester disease (ECD) have treatment-refractory disease or suffer recurrences. Recent findings of gene mutations in histiocytoses have generated options for targeted therapies. We sought to determine the utility of prospective sequencing of select genes to further characterize mutations and identify targeted therapies for patients with histiocytoses. Biopsies of 72 patients with a variety of histiocytoses underwent comprehensive genomic profiling with targeted DNA and RNA sequencing...

Histiocytosis X is an idiopathic disease, characterized by a disorder of the reticulo-endothelial system in the human body. Histopathological studies carried out right from the 1800s have seen a significant similarity in the pathologic process of different stages in particular clinical syndromes showing proliferation of mature histiocytes. It was then modified by Lichenstein in 1953 as "Histiocytosis X". The exact aetiology is unknown; hence, the name "Histiocytosis X". The disease classically presents with three syndromes namely Eosinophilic granuloma, Letterer-Siwe disease and Hand-Schuller-Christian disease...

PURPOSE: The standard evaluation of multisystem Langerhans cell histiocytosis (LCH) includes a clinical evaluation, laboratory tests and a skeleton/skull X-ray survey, with chest high-resolution computed tomography (HRCT) in the case of pulmonary involvement. Preliminary reports suggest that (18)F-fluorodeoxyglucose positron emission tomography-computed tomography ((18)F-FDG PET-CT) may be useful for evaluating patients with LCH. METHODS: Fourteen consecutive adult patients with multisystem LCH were included in this retrospective study, and were evaluated using standard procedures and (18)F-FDG PET-CT...

BACKGROUND: Langerhans cell histiocytosis (LCH), previously known as Histiocytosis X, is an infrequent disease that congregates a wide spectrum of clinical presentations with variable systemic involvement. Unification of these diseases under only one category is based on the almost identical histopathologic features of the lesions, but the etiology and proper approach for each presentation remains controversial. The localized alternative of Langerhans cell histiocytosis (LLCH), known as Eosinophilic Granuloma (EG) of bone, is the predominant clinical presentation of LCH...

Langerhans cell histiocytosis (LCH), formerly known as histiocytosis X, refers to a spectrum of diseases characterized by idiopathic proliferation of histiocytes that produce either focal (localized LCH) or systemic manifestations (Hand-Schüller-Christian disease and Letterer-Siwe disease). Localized LCH accounts for approximately 60-70 % of all LCH cases. Osseous involvement is the most common manifestation and typically involves the flat bones, along with lesions of the skull, pelvis, and ribs. Localized LCH in bone shows a wide spectrum of clinical manifestations and radiologic features that may mimic those of infections as well as benign and malignant tumors...

Langerhans cell histiocytosis (LCH) is a proliferation of Langerhans cells intermixed with inflammatory cells, in particular eosinophils, that may manifest as a unisystem (unifocal or multifocal) or multisystem disease. We describe the clinical and histologic spectrum of LCH of the orbit and skull in our two cases. Both cases had unifocal erosive skull lesions with a history of trauma. Typical histologic features included numerous histiocytes with varying degrees of giant cell formation and scattered eosinophilic granulocytes...

BACKGROUND: Langerhans cell histiocytosis (LCH) is a proliferative disease of histiocyte-like cells that generally affects children. Immunohistochemistry is essential to obtain the correct diagnosis, and treatment protocols are controversial. OBJECTIVE: Langerhans cell histiocytosis (LCH) is easy to be misdiagnosed because of its various clinic features and laboratory results. This research focused on the clinicopathological, histopathological, immunohistochemical and other features of LCH and aimed to analyze LCH clinical features for improving diagnosis and decreasing misdiagnosis rate...

BACKGROUND: Eosinophilic granuloma (EG) of bone refers to a generally benign form of Langerhans cell histiocytosis localized to the bone. Patients may present with a solitary lesion (monostotic) or multiple sites of involvement (polyostotic). MATERIALS AND METHODS: This study was done to evaluate the clinicopathological pattern of 6 cases of EGs of the skull diagnosed at a tertiary care hospital. All patients of EG were included with the help of medical records over a 5-year period that is, November 2009 to November 2014...

Few studies have used fine-needle aspiration cytology for the purpose of isolated skeletal Rosai-Dorfman diseases (RDDs) diagnosis.Herein, we described an extremely rare case of a 56-year-old woman who presented to our hospital with an insidious onset of pain in the right proximal tibia.The provisional cytologic diagnosis of RDDs was confirmed by a computer tomography-guided core needle biopsy of the lesion. Subsequently, curettage and autogenous iliac crest bone graft were performed successfully. At the 4th year of follow-up her clinical symptoms disappeared, and there was no clinical evidence of lesion recurrence...

The authors describe a 23-year-old man with unilateral upper eyelid swelling that evolved into a multinodular lesion with central necrosis, mimicking a neoplasm. Biopsy showed a lympho-histiocytic, eosinophil-rich proliferation with positivity for Langerhans cell markers CD1a and S-100 and histiocytic marker CD68. A literature review disclosed 11 documented cases of Langerhans cell histiocytosis of the eyelid with variable clinical presentations. This rare eyelid lesion, nearly always solitary, has no clinically distinctive characteristics and requires biopsy for diagnosis...

Langerhans cell histiocytosis (LCH) as a term encompasses eosinophilic granuloma and two clinical syndromes: Letterer-Siwe disease and Hand-Schüller-Christian. All these syndromes seem to represent similar processes in which the proliferating cells have the structural and functional features of Langerhans cells. In reviewing the literature found that this disease does indeed occur in some families more often than would be expected. We present two boys, siblings with LCH in a single family with two different entities (There were no other siblings) and this paper is presented to emphasize the very rare familial occurrence of EG and the other one with Letterer-Siwe disease in our single family...

Rosai-Dorfman disease (RDD) or sinus histiocytosis is a rare histiocytic disorder characterized by massive lymphadenopathy and with extranodal involvement in 25% to 43% of cases. The clinical course of RDD is unpredictable with episodes of exacerbation and remissions that can last many years, and treatment strategies can be different according to organ involvement. We report a case of a 42-year-old woman with extranodal disease followed for almost 10 years from the diagnosis who underwent seven (18)F-FDG PET/CT...

In infants, Langerhans cell histiocytosis (LCH) is associated with poor clinical outcomes as Langerhans cells invade and damage multiple organs, a presentation that is different from that in adults. Here, we present a case of a 15-year-old female who visited ourclinic complaining of right chest pain and dyspnea. She was diagnosed with right pneumothorax by chest X-ray. Chest computed tomography showed multiple cystic changes in the bilateral lung. Additionally, bullous lesions occupying the upper lobe and multiple white tiny nodules on the surface of the lung were observed by thoracoscopy...

We describe two new cases of Rosai-Dorfman disease with intrascrotal involvement. Also known as sinus histiocytosis with massive lymphadenopathy, this is a rare entity, usually presenting with massive bilateral cervical lymphadenopathy. It is associated with extranodal involvement in up to 40% of cases, commonly in the face and neck area. Isolated intrascrotal involvement with no lymphadenopathies is extremely rare, and its definitive diagnosis is histopathological. Although they are the most frequent type, not all intrascrotal lesions are neoplastic; therefore, it is important to know other possible etiologies and their radiogical features that might help in the diagnosis...
