Abstract:
CDK4/MDM2 co-amplification, a molecular aberration predominantly observed in sarcomas, has not been previously reported in odontogenic neoplasms. We present the first documented case of odontogenic carcinoma with CDK4/MDM2 co-amplification. The tumor exhibited distinctive histologic features including irregular luminal/cleft structures lined by monolayer epithelium over whorled stromal cores. This case expands both the histopathological spectrum and molecular landscape of odontogenic carcinomas. Furthermore, our findings support routine molecular profiling for rare odontogenic malignancies to improve classification and suggest potential theraputic targets.

M-Cdk Drives Transition Into Mitosis
Cyclin-dependent kinases, or Cdks, work in concert with cyclins to control cell cycle transitions. M-Cdk, a complex of Cdk1 bound to M cyclin, is a well-known example of this coordinated control that drives the transition from the G2 to the M phase.
