Metastases are usually an ominous finding. They are not always obvious when in encounter; thus, they should be considered with every diagnosis of a malignant tumour.

Special types

In-transit metastasis

Definition - the metastatic tumour must be:^[1]

>2 cm from the primary tumour.
Arises between the nearest (regional) lymph nodes and the primary tumour.
- The tumour presumably arises from a lymphatic that drains the tissue in which the primary tumour grew.

Notes:

It is called "in-tranist", as it happens while the tumour is on the way to the regional lymph node.
In-transit metastases are common in malignant melanoma.
