Axillary tumor deposits in primary breast carcinoma: a case report

Although tumor deposits are correlated with poor prognosis in other cancers, particularly in colorectal and gastric cancer, limited data are available for breast cancer. Owing to the unclear diagnostic criteria, they are often considered as lymph node metastases. To address this issue, we recommend reporting tumor deposits, and we encourage further studies on larger cohorts to better define their prognostic value and eventually, discuss their inclusion in the tumor, node, metastasis staging system.
