K13.4:
- 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.
- 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.
- 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.
