Chromosomal translocations, also translocations, may be characteristic of a tumour or simply narrow down the diagnosis to a set of tumours.

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
