NCIt related terms : Unifocal Langerhans Cell Histiocytosis; Monostotic Langerhans Cell Histiocytosis; Chronic Unifocal Langerhans Cell Histiocytosis; Eosinophilic Xanthomatous Granuloma; Unifocal Langerhans-cell histiocytosis;
NCIt definition : A clinical variant of Langerhans cell histiocytosis characterized 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 characterized by the presence of Langerhans cells in a characteristic
milieu which includes histiocytes, eosinophils, neutrophils, and small, mature lymphocytes.;
