Cutaneous histiocytic proliferations

The histiocytic proliferations in the skin include :
- proliferations of monocytes (acute monocytic leukemia),
- proliferations of tissue macrophages or histiocytes (histiocytic sarcoma and its disseminated form, malignant histiocytosis; familial histiocytoses; and multicentric reticulohistiocytosis),
- proliferations of Langerhans’ cells (histiocytosis X),
- proliferations of as yet undefined cells of the mononuclear phagocyte system (sinus histiocytosis with massive lymphadenopathy).

Examples

- cutaneous Langerhans cell histiocytosis
