Overview
Langerhans cell histiocytosis may be classified according to the extent of organ involvement into 4 groups: pulmonary Langerhans cell histiocytosis, unifocal Langerhans cell histiocytosis, multifocal unisystem Langerhans cell histiocytosis, and multifocal multisystem Langerhans cell histiocytosis.[1][2]
Classification
- Langerhans cell histiocytosis may be classified according to the extent of organ involvement into 4 groups: pulmonary Langerhans cell histiocytosis, unifocal Langerhans cell histiocytosis, multifocal unisystem Langerhans cell histiocytosis, and multifocal multisystem Langerhans cell histiocytosis.[1][2]
- The table below lists the features of each specific Langerhans cell histiocytosis subtype:[3][4][5]
| Subtype | Organ Involvement | Age | Risk Factors | Prognosis |
|---|---|---|---|---|
| Pulmonary Langerhans cell histiocytosis | Isolated pulmonary involvement | Adults | Occurs exclusively among smokers | Good prognosis with smoking cessation |
| Unifocal Langerhans cell histiocytosis | Isolated bone involvement | 2–10 years of age | Familial predisposition | Good prognosis, may spontaneously regress |
| Multifocal unisystem Langerhans cell histiocytosis | Triad of diabetes insipidus, exopthalmos, and lytic bone lesions | 2–10 years of age | Familial predisposition | Good prognosis, may spontaneously regress |
| Multifocal multisystem Langerhans cell histiocytosis | Involves skin, lungs, bone, and GI tract | < 2 years of age | Familial predisposition | Poor prognosis |
