Langerhans’ cell histiocytosis (LCH) is a rare disease of unknown aetiology involving accumulation of Langerhans’ cell histiocytosis, organised in granuloma, in various organs [1]. Pulmonary LCH (PLCH), is characterised by focal Langerhans’ cell granulomas infiltrating and destroying distal bronchioles, which results in cysts, major destruction of the pulmonary tissue and pneumothorax [2, 3]. P...
histiocytosis of langerhans cells (class 1 histiocytosis) consists of a range of clinical manifestations, including bone eosinophilic granuloma, hand-schüller-christian syndrome, and letterer-siwe disease. these syndromes represent a spectrum of severity and prognosis of an underlying disorder which is usually sporadic. this report describes three cases in one family, who developed the disease ...
conclusions a high index of suspicion is required for the early diagnosis and prompt treatment of patients with osseous tuberculosis. given the high prevalence of tuberculosis in developing countries, tuberculosis should be considered in the differential diagnosis of multifocal lytic lesions and vertebra plana, especially in children. introduction multifocal skeletal tuberculosis is a rare cond...
(lch) langerhans cell histiocytosis یک بیماری نادر با انفیلتراسیون سلولهای لانگرهانس، هیستیوسیت، لنفوسیت و ائوزینوفیل ها می باشد. اتیولوژی این بیماری کاملا مشخص نشده است. بیماری می تواند به صورت لوکالیزه یا منتشر و حاد یا مزمن دیده شود. در بسیاری از مواقع تظاهرات دهانی به عنوان اولین علایم بیماری بروز پیدا می کنند. در مقاله حاضر، یک مورد از langerhans cell histiocytosis در یک پسر بچه 3 ساله که ...
Langerhans cell histiocytosis (LCH) is a proliferative disorder of langerhans cells and lymphocytes having different subtypes and a wide range of clinical manifestations and severity ranging from a unifocal self-limited disorder to multi-system involvement and even death. Along with clinical manifestations, diagnosis is made through existence of specific immunohistochemistry markers. Where trea...
CONTEXT Pulmonary Langerhans cell histiocytosis is the most common and best known pulmonary histiocytic lesion; however, the realm of pulmonary histiocytic lesions also includes an assortment of uncommon diseases that may exhibit pulmonary involvement. OBJECTIVE To review pulmonary Langerhans cell histiocytosis and other pulmonary histiocytoses to better ensure correct diagnosis and optimal a...
Adult pulmonary Langerhans’ cell histiocytosis is a rare disorder of unknown aetiology that occurs predominantly in young smokers, with an incidence peak at 20–40 yrs of age. In adults, pulmonary involvement with Langerhans’ cell histiocytosis usually occurs as a single-system disease and is characterised by focal Langerhans’ cell granulomas infiltrating and destroying distal bronchioles. High-...
The synchronous or metachronous development of Langerhans cell histiocytosis and non-Langerhans cell histiocytosis in the same patient is rare. To date, only seven cases of xanthogranulomas developing in young patients with a history of Langerhans cell histiocytosis and systemic therapy have been reported in the literature. As of yet, the pathogenesis and the clinical significance of this pheno...
Clinical features, brain magnetic resonance imaging findings and EDSS scores of 11 patients with neurodegenerative central nervous system Langerhans cell histiocytosis were analyzed in Japan. All patients initially had multi-system-type Langerhans cell histiocytosis; 8 at 1-2 years of age and 3 at a later age. Neurodegenerative central nervous system Langerhans cell histiocytosis disease develo...
