Oral manifestations of Langerhans cell histiocytosis: A case series

Special Care in Dentistry: managing special patients, settings, and situations, 2018
AIM Langerhans cell histiocytosis (LCH) is an unusual proliferative disorder of bone marrow-derived histiocytes (Langerhans cells) that can produce focal or systemic manifestations. Oral manifestations of LCH can present as single or multiple lesions and

Langerhans cell histiocytosis in the adult

Medical and Pediatric Oncology, 1996
A study of 47 well-documented patients with Langerhans cell histiocytosis (LCH) showed a slight female preponderance, with onset as late as the ninth decade. The skin was the commonest site of presentation, but pulmonary and bone involvement was frequent. Patients with single-site disease did best.

Langerhans’ cell histiocytosis in adults

Journal of the American Academy of Dermatology, 1997
Three cases of Langerhans' cell histiocytosis with unusual clinical and histopathologic features are described. The first two cases illustrate diagnostic pitfalls that underscore the importance of considering Langerhans' cell histiocytosis in the differential diagnosis of purpuric papular eruptions of the scalp and intertriginous areas, particularly in

Differentiation of Langerhans cells in Langerhans cell histiocytosis

Blood, 2001
Langerhans cell histiocytosis (LCH) consists of lesions composed of cells with a dendritic Langerhans cell (LC) phenotype. The clinical course of LCH ranges from spontaneous resolution to a chronic and sometimes lethal disease. We studied 25 patients with various clinical forms of the disease.

Langerhans' cells histiocytosis.

International journal of pediatric otorhinolaryngology, 1999
Langerhans cell histiocytosis (LCH) is a rare disorder of unknown cause, characterized by the proliferation of histiocytic cells in various tissues and organs. The role of the otolaryngologist is important in the early and accurate evaluation, staging and diagnosis of LCH, because it may mimic more common diseases such as otitis externa and acute ...

Biology of Langerhans Cells and Langerhans Cell Histiocytosis

2006
Langerhans cells (LC) are epidermal dendritic cells (DC). They play an important role in the initiation of immune responses through antigen uptake, processing, and presentation to T cells. Langerhans cell histiocytosis (LCH) is a rare disease in which accumulation of cells with LC characteristics (LCH cells) occur. LCH lesions are further characterized
