Ontology: Eosinophilic Granuloma (C0014461)

Definition (MSH) The most benign and common form of Langerhans-cell histiocytosis which involves localized nodular lesions predominantly of the bones but also of the gastric mucosa, small intestine, lungs, or skin, with infiltration by EOSINOPHILS.
Definition (MSHCZE) Lokalizovaná forma granulomatózy z Langerhansových buněk (histiocytózy X). Postiženy mohou být plíce či kosti (osteolytický nádor), průběh je relativně benigní. Histologicky jsou četné eozinofily. (cit. Velký lékařský slovník online, 2013 http://lekarske.slovniky.cz/ )
Definition (NCI) A clinical variant of Langerhans cell histiocytosis characterised by unifocal involvement of a bone (most often), skin, or lung. Patients are usually older children or adults usually presenting with a lytic bone lesion. The etiology is unknown. Morphologically, eosinophilic granuloma is characterised by the presence of Langerhans cells in a characteristic milieu which includes histiocytes, eosinophiles neutrophiles, and small, mature lymphocytes.
Definition (CSP) most benign clinical form of Langerhans-cell histiocytosis, which involves localized nodular lesions of the gastric mucosa, small intestine, bones, lungs, or skin, with infiltration by eosinophils; the proliferating cell that appears to be responsible for the clinical manifestations is the Langerhans cell.
