Nodular fasciitis, a benign soft-tissue lesion that can mimic malignancies, may benefit from molecular testing for accurate diagnosis. A retrospective review of 29 cases revealed diverse clinical presentations and histopathological features that often led to misdiagnosis, requiring aggressive treatments. Significant findings included the detection of USP6 gene fusions through next-generation sequencing, which aided in diagnosis, while fluorescence in situ hybridization (FISH) showed some limitations. The variability in presentation necessitates careful evaluation to prevent overtreatment.
