Cystic metastatic tumor deposits are rare, and have been reported in a few tumor types, most commonly in the head and neck region, but rarely described with metastatic mammary carcinoma. We report a case of a 61-year-old female who presented with a large right axillary mass. Imaging studies revealed a cystic axillary mass and ipsilateral breast mass. She was managed with breast conservation surgery and axillary dissection for invasive ductal carcinoma, no special type, Nottingham grade 2 (21 mm). One of nine lymph nodes contained a cystic nodal deposit (52 mm), which resembled a benign inclusion cyst. Oncotype DX recurrence score for the primary tumor was low (8), conferring a low risk of disease recurrence despite the large size of the nodal metastatic deposit. A cystic pattern of metastatic mammary carcinoma is rare and important to recognize for accurate staging and management decisions.<\/jats:p>","DOI":"10.1177\/10668969231152574","type":"journal-article","created":{"date-parts":[[2023,2,20]],"date-time":"2023-02-20T01:34:37Z","timestamp":1676856877000},"page":"1409-1413","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Metastatic Mammary Carcinoma Presenting as a Large Cystic Axillary Mass: A Report of an Unusual Case"],"prefix":"10.1177","volume":"31","author":[{"given":"Allison K.","family":"Maybank","sequence":"first","affiliation":[{"name":"Department of Pathology, Nova Scotia Health and Dalhousie University, Halifax, NS, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Heather","family":"Curtis","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Radiology, Nova Scotia Health and Dalhousie University, Halifax, NS, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Trevor","family":"Topp","sequence":"additional","affiliation":[{"name":"Department of Surgery, Nova Scotia Health and Dalhousie University, Halifax, NS, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2346-7186","authenticated-orcid":false,"given":"Penny J","family":"Barnes","sequence":"additional","affiliation":[{"name":"Department of Pathology, Nova Scotia Health and Dalhousie University, Halifax, NS, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2023,2,19]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmu.2013.04.005"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1530\/EDM-18-0105"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0000000000016659"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.178.3.1780693"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1177\/10668969211003959"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.athoracsur.2019.03.038"},{"key":"e_1_3_3_8_2","doi-asserted-by":"publisher","DOI":"10.1002\/dc.24550"},{"key":"e_1_3_3_9_2","doi-asserted-by":"publisher","DOI":"10.1038\/sj.bjc.6690229"},{"key":"e_1_3_3_10_2","doi-asserted-by":"publisher","DOI":"10.1002\/dc.10201"},{"key":"e_1_3_3_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.clinimag.2016.12.006"},{"key":"e_1_3_3_12_2","doi-asserted-by":"publisher","DOI":"10.1186\/s12885-018-5260-2"},{"key":"e_1_3_3_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.path.2021.11.002"},{"key":"e_1_3_3_14_2","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(19890101)63:1<181::AID-CNCR2820630129>3.0.CO;2-H"},{"key":"e_1_3_3_15_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.path.2017.09.004"},{"key":"e_1_3_3_16_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa041588"},{"key":"e_1_3_3_17_2","doi-asserted-by":"publisher","DOI":"10.1200\/JCO.2005.04.7985"},{"key":"e_1_3_3_18_2","unstructured":"Genomic Health Inc. http:\/\/www.genomichealth.com (accessed April 26 2022). 2022."},{"issue":"6","key":"e_1_3_3_19_2","first-page":"1","article-title":"Mechanisms of cyst formation in metastatic lymph nodes of head and neck squamous cell carcinoma","volume":"7","author":"Mokahari S","year":"2021","unstructured":"Mokahari S.
