#>2 cm from the primary tumour.
*It is called "in-transit", as it happens while the tumour is on the way to the regional lymph node.
#Arises between the nearest (regional) [[lymph node]]s and the primary tumour.
*If a separate tumour nodule is close to the primary tumour, it is known as ''satellitosis''.
#*The tumour presumably arises from a lymphatic that drains the tissue in which the primary tumour grew.


Notes:
Note:
*It is called "in-transit", as it happens while the tumour is on the way to the regional lymph node.
*The definitions vary based on the primary site.
*If a separate tumour nodule <= 2 cm from the primary tumour, it is known as ''satellitosis''.
**The general definition (see the ''[[in-transit metastasis]]'' article) applies to [[dermatopathology]].
*[[Tumour deposits]] - in the context of [[colorectal carcinoma]] - can be understood as being the same thing; however, the details of the various definitions are different than the one above.
**In the [[colon]] and [[rectum]], they are generally known as ''[[tumour deposits]]'', ''discoutinuous extramural extension'' and ''peritumoral deposits''.<ref name=pmid19136930>{{Cite journal  | last1 = Puppa | first1 = G. | last2 = Ueno | first2 = H. | last3 = Kayahara | first3 = M. | last4 = Capelli | first4 = P. | last5 = Canzonieri | first5 = V. | last6 = Colombari | first6 = R. | last7 = Maisonneuve | first7 = P. | last8 = Pelosi | first8 = G. | title = Tumor deposits are encountered in advanced colorectal cancer and other adenocarcinomas: an expanded classification with implications for colorectal cancer staging system including a unifying concept of in-transit metastases. | journal = Mod Pathol | volume = 22 | issue = 3 | pages = 410-5 | month = Mar | year = 2009 | doi = 10.1038/modpathol.2008.198 | PMID = 19136930 }}</ref>
