INTRODUCTION Langerhans cell histiocytosis is a rare disease in children, initial presentation is variable, clinical course, prognosis and survival are mostly unpredictable. OBJECTIVE To summarise clinical characteristics and treatment results in children with Langerhans cell histiocytosis. METHOD Retrospectively there were analyzed patients with LCH diagnosed and treated at Hematology Department of University Children's Hospital in Belgrade from 1990 to 2006. Clinical presentation, therapy and survival according to Kaplan-Meier's statistical test was analysed. RESULTS 30 patients were treated, aged from 4 months to 14 years, mean 3.9 years, median 2.3 years, 18 (60%) males, 12 (40%) females. A single system disease was diagnosed in 16 (53%) patients, of whom 6 patients with multifocal bone disease. All patients were in complete remission averagely following162 and 82 months respectively. Multisystem disease was found in 14 (47%) patients. The lymph nodes and skin were more frequently involved organs than the central nervous system (diabetes insipidus), lung, liver and spleen. The number of involved organs ranged from 2 to 8, mean 4.2. Four patients died due to disease progression 3, 16, 36 and 66 months after diagnosis. Nine patents with multisystem disease were in remission with 117 months of follow-up. One patient was lost on follow-up. CONCLUSION The clinical course of patients with a single system disease is usually benign while a multisystem disease has to be aggressively treated with precise initial evaluation and staging before therapy.

System Disease

Histiocytosis is a heterogenous group of disorders that are characterized by proliferation and activation of mononuclear phagocyte system. Langerhans Cell Histiocytosis (LCH) or Class I histiocytosis is a rare disorder of unknown etiology with proliferation of Langerhan cells which may infiltrate a single or multiple organs. This disease is more common in infants and children. It is usually sporadic but a familial pattern is known. The term embraces the whole clinical spectrum of the disorder from single bone lesions (eosinophilic granuloma) to an aggressive widespread multisystem disease in very sick child (Letterer-Siwe disease) with a wide variety of intermediate forms including the Hand-shuller Christian triad. The cause of LCH is not firmly established and most investigators in the field have long suspected that LCH is immunologic disorder either in its etiology or in its pathophysiology. Recent evidence suggests that LCH is a clonal disorder rather than reactive disease. LCH is classified according to sites of involvement into single system disease and multisystem disease. Single system disease can be either unifocal or multifocal. Multisystem disease can be either without organ dysfunction or with organ dysfunction. Clinical course of LCH with single system disease is usually benign with high chance of survival. However, its clinical course is often unpredictable and patients can experience spontaneous remission and exacerbations. Histiocytic diseases are currently classified by the writing group of the Histiocyte Society in the three classes, namely;Class I: Langerhans Cell Histiocytosis (LCH) Class II: Histiocytosis of mononuclear phagocytes other than Langerhans Cells Class III: Malignant Histiocytic disorders Key words: Langerhans Cell Histiocytosis, Eosinophilic granuloma, Skull, lytic lesion doi:10.3126/jnps.v27i2.1587 J.

ABSTRACT Langerhans cell histiocytosis (LCH) is characterised by an abnormal histiocytic accumulation in tissues such as the lung, spleen, bone marrow, skin, central nervous system, liver and lymph nodes, causing focal or systemic effects. No specific clinical & radiographic presentation of LCH is described in literature. This poses a diagnostic dilemma for surgeons. The scapula is the site of 3% of bone tumours, while for LCH it is the least common site. In a 10-year-old boy with isolated lesion of the scapula with no other systemic involvement, and no specific finding in MRI or CT scan of scapula, diagnosis was confirmed on biopsy. Division into single and multi-system disease is paramount in treatment, given that it is a single system disease. The patient improved clinically on follow-up of 2 years. The scapula is one of the rarest site of LCH, and because various lesions mimic each other, a biopsy is always required, with immunohistochemistry for CD68 & S-100. This was only a single system disease, so conservative management was performed, and the patent improved clinically.

Underlying Pathology

Summary Histiocytoses comprise a group of diverse diseases of unknown etiology with various clinical presentation and evolution. The underlying pathology is characterised by accumulation and infiltration of variable numbers of cells of the monocyte-macrophage line in the affected tissues and organs. Histiocytoses are divided into three major classes: Langerhans cell histiocytosis (LCH), non- Langerhans cell histiocytosis, and malignant histiocytic disorders. The term LCH (also known in the past as histiocytosis X) encompasses the following rare diseases: Eosinophilic Granuloma, Hand-Schuller-Christian disease, Letterer-Siwe disease, Hashimoto-Pritzker disease, in which accumulation of pathologic Langerhans cells (LCs) leads to tissue damage. LCs usually reside in the skin and ensure protection against infections by destroying foreign substances. LC accumulation is caused by antigen stimulation and inadequate immune response. Thus, clinical LCH manifestations range from isolated disease with mono- or multifocal bone lesions to disseminated multisystem disease. LCH is a rare disease, affecting mainly children and young smokers, aged 20-50 years. Lung involvement in LCH usually presents as a mono-system disease and is characterized by Langerhans cell granulomas (LCG) infiltrating and impairing the distal bronchioles. The definite diagnosis is based on lung biopsy of CAT selected LCG areas. So far, there is no an effective treatment, but the better understanding of the mechanisms involved in the pathogenesis of the disease would help in the development of effective therapeutic strategies in the future.
