Journal of Investigative Dermatology, 1965 Since Langerhans (1) first described the presence of gold-positive dendritic cells in the epidermis, their nature has been an unsettled question. These cells, which morphologically resemble melanocytes, are free of pigment and are not seen when stained for melanin nor when the dopa stain is used; but they can be demonstrated with gold chloride methods.

Journal of Investigative Dermatology, 1983 Langerhans cells are the bone-marrow-derived immune cells of the epidermis; they express Ia antigens and receptors for the Fc portion of IgG and complement components and are required for epidermal-cell-induced antigen-specific, syngeneic and allogeneic T-cell activitation and the generation of epidermal-cell-induced cytotoxic T cells.

Langerhans cell histiocytosis [PDF]
Sao Paulo Medical Journal, 1998 The authors present a rare case of Langerhans cell histiocytosis in a 31 year old female patient with vulvar, peri-anal and oral lesions, diabetes insipidus, pulmonary skin and bone infiltrations. Skin biopsy immunohistochemistry presented positive S100 protein and vimentine, but the diagnosis was done with the demonstration of Birbeck granules with ...

Journal of Medical Case Reports, 2021 Background Langerhans cells belong to the histiocytic system and give rise to two tumors: Langerhans cell histiocytosis and Langerhans cell sarcoma. Clinical aggressiveness and degree of atypia distinguish the two neoplasms. Langerhans cell histiocytosis

The Potentials and Pitfalls of a Human Cervical Organoid Model Including Langerhans Cells
Viruses, 2020 Three-dimensional cell culturing to capture a life-like experimental environment has become a versatile tool for basic and clinical research. Mucosal and skin tissues can be grown as “organoids” in a petri dish and serve a wide variety of research ...

Journal of Indian Society of Periodontology, 2011 Langerhans cell histiocytosis (LCH) is a group of rare disorders histologically characterized by the proliferation of Langerhans cells. Multiple organs and systems may be involved by the disease. Typically, there is bone involvement and, less frequently, lesions may be found in the lungs, liver, lymph nodes, skin, and mucosa.

Langerhans cell histiocytosis [PDF]
Blood, 2020 Abstract Langerhans cell histiocytosis (LCH) is caused by clonal expansion of myeloid precursors that differentiate into CD1a+/CD207+ cells in lesions that leads to a spectrum of organ involvement and dysfunction. The pathogenic cells are defined by constitutive activation of the MAPK signaling pathway.
