Primary tumor versus metastasis
Indications of a metastasis rather than primary tumor are mainly:
- Tumors that are unlikely to arise at the location at hand.
- Tumors conforming to more likely metastasis pathways.
If a suspected malignancy is present, generally check the patient history for any history of cancer, especially for tumors in more common metastasis sites, which mainly include lung, bone, liver and/or brain. In case of such history, preferably look at the microscopy slides of the past cancer to help determining whether the current case is of the same origin, versus a primary at the current body location, versus a metastasis of yet another location. If there is no known history of cancer, still consider a metastasis of unknown primary origin, especially for suspected malignancies in lymph nodes, liver, lungs, bones, or skin.[2]
