Collision tumour is a tumour that developed from two separate tumours that are pathologically distinct.[1][2]
General
Microscopic
Features:
- Two histologically distinct juxtaposed tumours.
- Tumour components should not intermingle.[3]
DDx:
- Tumour with different histologic patterns, e.g. unclassified renal cell carcinoma.
- Tumour with different histologic grades, and a sharp transisition between different grades.
