Lymphocyte sub-populations and non-Langerhans’ cell monocytoid cells in pulmonary Langerhans’ cell histiocytosis

Pathology - Research and Practice, 2008
Pulmonary Langerhans' cell histiocytosis (PLCH) is a disease characterized by the occurrence of complex fibro-cellular interstitial lesions dominated by Langerhans' cells (LC), which occurs predominantly in young adult smokers. We undertook this retrospective study to better define the lymphohistiocytic cell populations in PLCH in order to obtain a ...

Erdheim- Chester Disease (Non-Langerhans Cell Histiocytosis)

Journal of Cancer Research Reviews & Reports
52 years old female with recurrent admission for myalgias, inflammatory arthritis, rash around the eyes and abdomen (A, B). Routine blood tests were either normal or negative apart from low C4 level. Pan CT of the body was unremarkable.

GENERALIZED NON‐LANGERHANS CELL HISTIOCYTOSIS: FOUR CASES ILLUSTRATE A SPECTRUM OF DISEASE

International Journal of Dermatology, 1995
Abstract Background. The proliferation of non‐Langerhans cell histiocytes is a poorly understood process of unknown cause. Variation in the clinical features and/or histopathology of histiocytic proliferation has led to subclassification of the general category of non‐Langerhans cell histiocytes.

Diffuse xanthogranulomatous dermatitis and systemic Langerhans cell histiocytosis: A novel case that demonstrates bridging between non-Langerhans cell histiocytosis and Langerhans cell histiocytosis

Journal of the American Academy of Dermatology, 2009
The advent of electron microscopy and immunohistochemical stains allowed for reclassification of the histiocytoses based on the predominant cell in the infiltrate. Although the current schema simplicity provides a good foundation, some patients display overlapping clinical and immunohistochemical features that defy classification.

Immunohistochemical Expression of Langerin in Langerhans Cell Histiocytosis and Non-Langerhans Cell Histiocytic Disorders

American Journal of Surgical Pathology, 2008
Langerin is a type II transmembrane C-type lectin associated with the formation of Birbeck granules in Langerhans cells. Langerin is a highly selective marker for Langerhans cells and the lesional cells of Langerhans cell histiocytosis. Although Langerin protein expression in Langerhans cell histiocytosis has been previously documented, the specificity

A unique non-Langerhans cell histiocytosis with some features of generalized eruptive histiocytoma

Journal of the American Academy of Dermatology, 1994
A symmetric eruption of hundreds of coalescent small red macules and a few slightly elevated papules sparing the flexures was observed in a 73-year-old man. Light microscopic examination showed loose aggregates of small and large histiocytic cells. Electron microscopy showed an absence of Langerhans cell granules and lipid droplets.

Successful treatment of Erdheim-Chester disease, a non–Langerhans-cell histiocytosis, with interferon-α

Blood, 2005
AbstractErdheim-Chester disease is a rare non-Langerhans histiocytosis with multisystem involvement. To date, there is no standard treatment for this disorder, and more than half of the patients succumb within 3 years. Because interferon-α promotes the terminal differentiation of histiocytes and dendritic cells, we hypothesized that this molecule would

[Acquired regressive cutaneous non-Langerhans-cell histiocytosis in an infant].

Annales de dermatologie et de venereologie, 1998
Cutaneous histiocytosis of childhood often regresses spontaneously without treatment. In some cases however, it is difficult to differentiate aggressive forms and electron microscopy and immunohistochemistry can be a valuable help. We report a case of cutaneous histiocytosis in a child which illustrates the difficulties encountered in the ...

Non-langerhans Cell Histiocytosis-Including Erdheim-Chester Disease- and the Lung

2014
Erdheim-Chester disease (ECD) is a rare form of non–Langerhans’ cell histiocytosis that may present with pulmonary involvement. The disease was first described as the “lipoid granulomatose” in 1930. Between then and 2013, more than 500 cases have been reported.
