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 concomitant inflammatory infiltrate; in addition, there was strong immunohistochemical PDGFRα overexpression. Methylation profiling (Sarcoma classifier v12.2) was consistent with IMT (calibrated score 0.99). Herein, we review other soft tissue tumors with PDGFRA fusions, emphasizing PDGFRA::USP8 fusions, further highlighting the genetic pleiotropy of kinase gene fusions in soft tissue tumors. In addition, this case expands the landscape of kinase fusions in IMT, presented by an extremely rare cutaneous IMT.
期刊介绍:
Genes, Chromosomes & Cancer will offer rapid publication of original full-length research articles, perspectives, reviews and letters to the editors on genetic analysis as related to the study of neoplasia. The main scope of the journal is to communicate new insights into the etiology and/or pathogenesis of neoplasia, as well as molecular and cellular findings of relevance for the management of cancer patients. While preference will be given to research utilizing analytical and functional approaches, descriptive studies and case reports will also be welcomed when they offer insights regarding basic biological mechanisms or the clinical management of neoplastic disorders.
