Lobular capillary haemangioma (LCH), previously known as pyogenic granuloma, is a benign vascular lesion commonly found within the oral and nasal cavity. However, it is rarely encountered within the trachea, where presenting features include recurrent haemoptysis, cough, and wheeze. We here describe a case of a 7 mm tracheal LCH in a 56-year-old woman, which was successfully resected at interve...

Langerhans cell histiocytosis (LCH) has been previously thought of as a rare illness, but is now increasingly diagnosed as a result of the more intensive investigations of patients with cystic pulmonary disease. In recent years, treatments developed from our new understanding of the molecular biology of malignant disease have been applied to patients with LCH, and responses seen. In this review...

BACKGROUND Isolated mediastinal involvement in Langerhans cell histiocytosis (LCH) has been rarely reported. CASE CHARACTERISTICS A 3-month-old boy presented with history of low grade intermittent fever, cough and noisy breathing for 2 weeks. OBSERVATION A chest X-ray showed massive mediastinal widening. Biopsy of the mass confirmed LCH. OUTCOME Patient is doing well after one year of tre...

Langerhans cell histiocytosis (LCH) is a rare disorder that affects the pediatric population. LCH complicated with a neurologic deficit due to the presence of epidural involvement is a rare condition. We describe the CT imaging features in a 2-year-old boy who presented with drowsy consciousness resulting from an epidural hematoma caused by spontaneous bleeding in an LCH of the skull. CT is an ...

conclusions our study is the first to investigate patients with lch and its possible association with hhv-6 in iran. considering the p level of 0.11, which is statistically insignificant, our findings fail to support the hypothesis of a possible role for hhv-6 in the pathogenesis of lch. these results are in concordance with previous investigations showing negative results. results there was no...

Langerhans cell histiocytosis (LCH) is a rare disorder with numerous clinicopathological variants with differing clinical courses, treatment methods, and prognoses. We report one patient with atypical LCH of the bilateral lower eyelids and subsequent successful treatment with local radiation therapy.

BACKGROUND Langerhans cell histiocytosis (LCH) is a rare disease with a peak incidence in childhood. There is limited experience with treatment options for adult patients having multisystemic LCH involvement. We report successful treatment of a 70-year-old woman with adult onset of LCH and multisystem disease (diabetes insipidus centralis, bone marrow infiltration, and lung and skin involvement...

BACKGROUND Bone is the most common organ of involvement in patients with Langerhans cell histiocytosis (LCH), which is often painful and associated with significant morbidity from pathological fractures. Current first-line treatments include chemotherapy and steroids that are effective but often associated with adverse effects, whereas the disease may reactivate despite an initial response to f...

Langerhans cell histiocytosis (LCH) is characterized by a clonal proliferation and retention of cells with a Langerhans cell (LC)-like phenotype at various sites within the body. The present study set out to elucidate whether aberrant expression of chemokine receptors or dysregulation of chemokine production in LCH lesions could explain abnormal retention of these cells. Immunohistochemical ana...

INTRODUCTION Prior reports of Langerhans cell histiocytosis (LCH) suggest that isolated skin involvement is rare and often progresses to systemic disease. More rapid access to pediatric subspecialty care has likely led to more frequent representation of this condition. The purpose of this study is to characterize the natural history of skin-limited LCH in an era of increased access to pediatric...
