Keratin‐positive giant cell‐rich tumors of soft tissue with HMGA2::NCOR2 fusions

Journal of Cutaneous Pathology, Volume 50, Issue 11, Page 977-982, November 2023., 2023
Abstract Background Giant cell tumor of soft tissue (GCT‐ST) is a rare soft tissue neoplasm that is morphologically similar to but genetically distinct from giant cell tumor of bone. A novel keratin‐positive GCT‐ST (KPGCT‐ST) harboring HMGA2::NCOR2 fusions was recently discovered.

NTRK expression is common in xanthogranuloma and is associated with the solitary variant

Journal of Cutaneous Pathology, Volume 50, Issue 11, Page 991-1000, November 2023., 2023
Abstract Background Previously identified mutually‐exclusive driver genes in juvenile xanthogranuloma (JXG) and adult xanthogranuloma (AXG) include mutations in MAP kinase pathway genes such as MAP2K1, BRAF, ARAF, KRAS, NRAS, PIK3CD as well as fusions in BRAF and ALK, with a subset of cases with no identified driver yet. NTRK fusion has been identified

Summary Necrobiotic xanthogranuloma is a rare disease that is part of the non‐Langerhans cell histiocytoses. It is characterized by yellowish skin lesions, which are typically periorbitally localized. Extracutaneous manifestations of all organs are possible and can cause potentially life‐threatening complications.
