Molecular Heterogeneity and Clinicopathologic Correlations in Inflammatory Myofibroblastic Tumors of the Urinary Bladder: A Study of 20 Cases With Predominant FN1::ALK Fusions and Novel Kinase Rearrangements
{{output}}
Inflammatory myofibroblastic tumors (IMTs) of the urinary bladder are rare mesenchymal neoplasms with an incompletely defined molecular spectrum. This integrated clinicopathologic and molecular study of 20 bladder IMTs utilized immunohistochemistry (IHC), fluo... ...
