Chromosomal translocations, also translocations, may be characteristic of a tumour or simply narrow down the diagnosis to a set of tumours.
They fall into the category of molecular pathology.
Key point
The key point is:
- One should be aware of the existence of specific (i.e. diagnostic/near diagnostic) translocations and translocations which significantly narrow down the diagnosis -- which are available to (clinical) pathologists.
Unfortunate reality of residency
Translocations are often a subject of pimping and show-up on examinations.
List of translocations
