Malignant epithelioid neoplasm with GLI1 gene rearrangement (PANX3::GLI1 transcript) and MDM2 gene amplification.
We hereby report the case of an epithelioid neoplasm arising from pterygopalatine fossa in a 13-year-old child harboring PANX3::GLI1 fusion and MDM2 amplification. Identified chimeric gene can explain observed signs of osteogenic differentiation. We discuss the challenges in differential diagnosis from osteogenic tumors and soft tissue neoplasms with epithelioid morphology. Our case is the first report of a tumor with such genetic abnormalities and it is about to replenish the spectrum of rare GLI1-rearranged tumors.
期刊介绍：
Manuscripts of original studies reinforcing the evidence base of modern diagnostic pathology, using immunocytochemical, molecular and ultrastructural techniques, will be welcomed. In addition, papers on critical evaluation of diagnostic criteria but also broadsheets and guidelines with a solid evidence base will be considered. Consideration will also be given to reports of work in other fields relevant to the understanding of human pathology as well as manuscripts on the application of new methods and techniques in pathology. Submission of purely experimental articles is discouraged but manuscripts on experimental work applicable to diagnostic pathology are welcomed. Biomarker studies are welcomed but need to abide by strict rules (e.g. REMARK) of adequate sample size and relevant marker choice. Single marker studies on limited patient series without validated application will as a rule not be considered. Case reports will only be considered when they provide substantial new information with an impact on understanding disease or diagnostic practice.
