Abstract
Abstract
Background
Poorly differentiated sinonasal small round cell tumors (SRCTs) are rare and heterogeneous, posing challenges in diagnosis and treatment.
Methods
Recent advances in molecular findings and diagnostic refinement have promoted better understanding and management of these tumors.
Results
The newly defined and emerging sinonasal entities demonstrate diverse morphologies, specific genomic signatures, and clinical behavior from conventional counterparts. In this review of SRCTs, emphasis is placed on the diagnostic approach with the employment of a pertinent panel of immunohistochemistry studies and/or molecular tests, fine-tuned to the latest WHO 5 classification of sinonasal/paranasal tumors and personalized treatment.
Conclusion
Specifically, this review focuses on tumors with epithelial and neuroectodermal derivation.
