Incidental Collision Tumor: Two Common Metastases Meet in the Neck
We present a case of intranodal collision between HPV-positive oropharyngeal squamous cell carcinoma and incidental papillary thyroid carcinoma. These two common lesions of the head and neck highlight an emergent area of complicated histology and raise interesting questions about tumor biology. We briefly review the variations of composite lesions described in the head and neck, as well as the potential prognostic implications between different types and role of ancillary testing and molecular diagnostics in their separation.
