A unique non-Langerhans cell histiocytosis with some features of generalized eruptive histiocytoma
Journal of the American Academy of Dermatology, 1994A 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.

Suprasellar non-Langerhans cell histiocytosis (Erdheim–Chester disease)—a case report
Clinical Imaging, 2013Erdheim-Chester disease (ECD) is an uncommon non-Langerhans cell histiocytosis that affects multiple body systems and can present clinically in a myriad of ways. An adult onset is most common with bony involvement and constitutional symptoms. We report the case of a 52-year-old female presenting with diabetes insipidus and a suprasellar mass on imaging,

GENERALIZED NON‐LANGERHANS CELL HISTIOCYTOSIS: FOUR CASES ILLUSTRATE A SPECTRUM OF DISEASE
International Journal of Dermatology, 1995Abstract 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.

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

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

Benign Cephalic Histiocytosis Progressing Into Juvenile Xanthogranuloma
The American Journal of Dermatopathology, 2000Benign cephalic histiocytosis (BCH) is best understood as a form of non-Langerhans cell histiocytosis, specifically as an early mononuclear variant of juvenile xanthogranuloma (JXG). However, the progression of BCH into JXG in the same patient has only been reported once before.

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 ...

Non-langerhans Cell Histiocytosis-Including Erdheim-Chester Disease- and the Lung
2014Erdheim-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.

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.
