It is well established that Technetiummethylene diphosphonate (Tc MDP) whole body bone scintigraphy (WBBS) can demonstrate multiple lesions with increased radiotracer concentration in involved bone. But it is hard to differentiate multiple benign osteolytic lesions from disseminated bone metastases. Even combined with medical history and multiple imaging results, clinical diagnosis of metastati...

Resolution rate and qualitative characteristics of healing were studied in 71 osseous lesions of histiocytosis X. Rates of healing, as assessed planimetrically and by vertebral body-height measurement, did not differ significantly among lesions that were treated with chemotherapy alone, chemotherapy plus radiation, radiation alone, or those that received no treatment. Lesions of Letterer-Siwe d...

Langerhans cell histiocytosis (LCH), also designated as histiocytosis-X or eosinophilic granuloma, is an uncommon dendritic cell disorder characterized by the infiltration of abnormally proliferating Langerhans cells into 1 or more organs.1 The clinical presentation of LCH varies depending on the site(s) of involvement and aggressiveness of disease. In children, it may present as LettererSiwe d...

The lungs may be involved in patients with histiocytosis X as part of the generalised disease, but histiocytosis X confined to the lungs without extrapulmonary involvement is rare. This report describes two cases of primary pulmonary histiocytosis arising in patients with Hodgkin's disease. It is impossible to state with certainty whether the pulmonary histiocytosis arose as a response to the d...

BACKGROUND Eosinophilic granuloma (EG), one of the three clinical forms of Langerhans cell histiocytosis (LCH), is a benign inflammatory reaction to an unknown etiologic agent. It most commonly occurs in children and young adults. The most frequently involved bones are the skull, the ribs and the femurs. Alongside the cranium, the maxilla and mandible can also be affected. CASE DETAILS Herein...

Langerhans cell histiocytosis (LCH), mainly affects the skull, vertebrae, ribs and mandible in children and the long bones of adults. Symptoms range from none to pain, swelling and tenderness over the site of the lesion. This disease presents oral manifestations which can sometimes be the first expression of the condition. It occurs in three forms namely eosinophilic granuloma in which isolated...
