Background: Acetabular roof lesions (ARLs) in children are uncommon and may involve a variety of diseases. The acetabular roof is the main weight-bearing area of the hip joint, and lesions affecting the acetabular roof lead to fluid accumulation in the hip joint, causing hip pain and claudication. Methods for diagnosing and treating ARLs and the prognosis after treatment are rarely reported. Read More

Introduction: Langerhans cell histiocytosis (HL) is a rare disease that can affect all tissues. Oral manifestations such as mucosal ulcer and tooth mobility are often the first signs of the disease. We report a rare case of mandibular condyle unifocal HL mimicking a temporomandibular joint disorder. Read More

Eosinophilic granuloma (EG) is a rare bony disease deriving from abnormal proliferation of histiocytes, and is the most common form of presentation of Langerhans cell histiocytosis. EG predominantly affects the axial skeleton. However, when localised in the head and neck district, mandibular lesions account for the majority of cases. Read More

Background: Langerhans cell histiocytosis is a rare disease in the adult, predominates in the pediatric age and is more common in men than in women. The sites of greater affection are the long bones, followed by the bones of the skull. Patients usually have symptoms related to the site of affection, usually polyostotic lesions, monostotic lesions occur less frequently. Read More

Background: Bone necrosis of the jaw is a serious condition with a broad differential diagnosis of pathologies such as cutaneous histiocytosis, bone metastases or malignant tumours. In addition to the most common cause, medication related osteonecrosis of the jaw (MRONJ), one must consider a number of other causes, such as histiocytosis. Langerhans cell histiocytosis (LCH) is a histiocytic disorder with a large spectrum of clinical manifestations and with possible involvement of a variety of organs. Read More

Langerhans cell histiocytosis (LCH) is a childhood pathology with a peak of incidence ranging from 1 to 4 years of age, though diagnosis is often made in adult age. LCH is clinically classified into three types: eosinophilic granuloma, Hand-Schuller-Christian disease and Abt-Letterer-Siwe disease. We report a case of Hand-Schüller-Christian disease with diabetes insipidus, skull and maxillary involvement in a 16-year-old boy referred to our observation for gradual increase in mobility of the teeth and subsequent gradual loss of the second premolars and the first molars of the upper jaw.

Rationale: Primary osteosarcomas of the skull and skull base are rare, comprising <2% of all skull tumors. Primary osteosarcomas of the skull are aggressive neoplasms composed of spindle cells producing osteoid which have poor outcome.

Patient Concerns: A 33-year-old woman was admitted to our hospital with a major complaint of a growing mass on her left frontal region of the skull for 10 months. Read More

Histiocytoses are a group of heterogeneous diseases that encompass Langerhans cell histiocytosis and non-Langerhans cell histiocytosis. Cutaneous plane xanthoma is a non-Langerhans cell histiocytic disorder characterized by the presence of yellow-orange plaques on the face, neck, upper trunk and extremities. It can appear in association with several systemic diseases (including dyslipidemias, paraproteinemias, cardiovascular diseases and lymphoproliferative disorders), but is rarely connected with Langerhans cell histiocytoses.

The paper describes a case of eosinophilic granuloma of the parietal bone in a 32-year-old man. Histological examination revealed a large number of bean-shaped Langerhans cell histiocytes with lobed nuclei and nuclear grooves. The histiocytes alternated with the foci of obvious eosinophilic infiltration and with eosinophilic microabscesses. Read More

Rationale: Solitary eosinophilic granuloma (EG), the most benign, common form of Langerhans cell histiocytosis, has a self-limiting process and is associated with a good prognosis. Immobilization is recommended as the first treatment strategy for solitary EG, although the treatment protocols are still controversial. Radiotherapy and surgery are secondary treatment choices.

Purpose: The eosinophilic granuloma is a unifocal or multifocal Langerhans cell histiocytosis characterized by an expanding proliferation of Langerhans cells in bones. Skeletal LCH is a rare condition, and vertebral regeneration in cases of vertebral body collapse is even rarer. We report the case of a girl with spontaneous complete healing. Read More

Background: Eosinophilic granuloma (EG) of spine in pediatric patients presents kinds of clinical manifestation and a difficult management scenario. The choice of treatment, issues of surgical intervention versus conservative treatment, combination therapy or single treatment, all these factors, including neurological deficits, spinal stability, long-term complications, and continued skeletal growth, must be considered.

Methods: From 2008 to the 2015, 31 pediatric patients of spinal EG were retrospectively reviewed. Read More

Xanthomatous lesions of the sellar region have traditionally been divided into two separate categories, xanthomatous hypophysitis (XH) and xanthogranuloma (XG) of the sellar region. The seminal article on XH, a condition typified by foamy histiocytes and lymphoplasmacytic infiltrates in the pituitary gland/sellar region, but usually little or no hemosiderin pigment, detailed three patients. However, most reports since that time have been single cases, making understanding of the entity difficult. Read More

This review summarizes current concepts in the diagnosis and management of the patients with eosinophilic granuloma. Given the benign biology, the clinical course, and the pediatric group of patients that this condition more commonly affects, a treatment approach that carries a lower risk of complications while ensuring a successful cure is desirable. Variable treatment options have been reported with satisfactory results and a recurrence rate of less than 20 %. Read More

Spinal involvement occurs frequently in cases of eosinophilic granuloma (EG), but surgical treatment is limited primarily to those with spinal instability. Involvement of the cervical spine is rare, but primarily occurs in the vertebral bodies, and is normally amenable to anterior corpectomy and spinal reconstruction. The authors describe a 27-year-old man with pathologically proven EG who presented with complete destruction of the C-1 lateral mass requiring spinal stabilization. Read More

Intracranial Langerhans cell histiocytosis commonly presents as skull lesions in children. An intratumoral cyst with fluid level and epidural hematoma occurring with eosinophilic granuloma is very rare.

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. Read More

Eosinophilic granuloma is the most benign and common form of the Langerhans cell histiocytosis, a rare proliferative disease that can affect single or multiple organs. In the quite common head and neck manifestation these lesions can be confused in the beginning, with other bone diseases such as odontogenic cysts, periodontal disease, or malignancies. Treatment varies depending on the size, number, localization of the lesions, and patient's general conditions. Read More
