A '''tumour deposit''' is a microscopic or macroscopic tumour nodule in the lymphatic drainage bed of the (primary) tumour. The term is applied in [[colorectal adenocarcinoma]] and has also been described in [[gastric cancer]].<ref name=pmid23184289>{{Cite journal | last1 = Lee | first1 = HS. | last2 = Lee | first2 = HE. | last3 = Yang | first3 = HK. | last4 = Kim | first4 = WH. | title = Perigastric tumor deposits in primary gastric cancer: implications for patient prognosis and staging. | journal = Ann Surg Oncol | volume = 20 | issue = 5 | pages = 1604-13 | month = May | year = 2013 | doi = 10.1245/s10434-012-2692-9 | PMID = 23184289 }}</ref> | A '''tumour deposit''' is a microscopic or macroscopic tumour nodule in the lymphatic drainage bed of the (primary) tumour.
