CUtaneous histiocytoses are a heterogeneous group of disorders that are characterized by the proliferation and accumulation of reactive or neoplastic histiocytes.
Three classes of histiocytoses have been defined:
- class I, Langerhans cell histiocytosis;
- class II, non-Langerhans cell histiocytosis without features of malignancy;
- class III, malignant histiocytic proliferations.
Although the disorders in classes I and II usually have a benign appearance on histology and are commonly non-aggressive and self-healing, some can cause debilitating or even fatal outcomes.
