PDGFRA::USP8 Fusion in a Cutaneous Inflammatory Myofibroblastic Tumor, Highlighting Genetic Pleiotropy of Kinase Gene Fusions in Soft Tissue Neoplasms

Genes, Chromosomes and Cancer, Volume 64, Issue 2, February 2025.
ABSTRACT PDGFRA::USP8 fusions have recently been described in neoplasms in the provisional category of calcified chondroid mesenchymal neoplasm (CCMN). Here, we describe a cutaneous inflammatory myofibroblastic tumor (IMT) on the upper leg of a 24‐year‐old male harboring the same fusion product. The tumor showed a morphology typical of IMT, including a
