Some histiocytic lesions, such as histiocytic sarcoma, are inherently malignant, while others, like hemophagocytic lymphohistiocytosis (HLH), manifest as severe, potentially life-threatening systemic inflammatory syndromes. Recent molecular genetic studies revealed recurrent genetic alterations in the MAPK pathway, such as BRAF V600E and MAP2K1 in LCH and ECD, and KRAS, NRAS, and MAP2K1 mutations in a subset of RDD.
