We report a rare case of a 51-year-old female who presented with a complain of swelling and pain in the right axilla with no associated complaints in other organs. Magnetic resonance imaging suggested a possibility of metastatic lymphadenopathy. Complete excision of the right axillary mass was performed and sent for histopathological examination which was examined thoroughly and sections were given. On microscopic examination, stromal proliferation in a leaf-like pattern with mild stromal atypia and focal permeation of borders were seen, and a diagnosis of Ectopic borderline phyllodes tumor in axilla was made, which is extremely rare and needs to be differentiated from its close differentials like fibroadenoma and periductal stromal sarcoma.<\/jats:p>","DOI":"10.3233\/bd-230007","type":"journal-article","created":{"date-parts":[[2023,8,1]],"date-time":"2023-08-01T10:45:49Z","timestamp":1690886749000},"page":"245-249","source":"Crossref","is-referenced-by-count":2,"title":["Borderline phyllodes tumor arising in ectopic breast tissue in the axilla: Report of a rare case with brief review of literature"],"prefix":"10.1177","volume":"42","author":[{"given":"Mohammad Jaseem","family":"Hassan","sequence":"first","affiliation":[{"name":"Department of Pathology, , , , India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Saqib","family":"Ahmed","sequence":"additional","affiliation":[{"name":", , , , India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bushra","family":"Siddiqui","sequence":"additional","affiliation":[{"name":"Department of Pathology, , , , India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kafil","family":"Akhtar","sequence":"additional","affiliation":[{"name":"Department of Pathology, , , , India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Afzal","family":"Anees","sequence":"additional","affiliation":[{"name":"Department of General Surgery, , , , India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sayeedul Hasan","family":"Arif","sequence":"additional","affiliation":[{"name":"Department of Pathology, , , , India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mahboob","family":"Hasan","sequence":"additional","affiliation":[{"name":"Department of Pathology, , , , India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","reference":[{"key":"10.3233\/BD-230007_ref1","unstructured":"Lakhani SR, Ellis IO, Schnitt SJ, Tan PH, van de Vijver MJ (eds), World Health Organization Classification of Tumors of the Breast, (Lyon), IARC Press,\u00a0 2012."},{"key":"10.3233\/BD-230007_ref2","doi-asserted-by":"crossref","first-page":"376","DOI":"10.1016\/S0002-9610(05)80849-9","article-title":"Phyllodes tumors","volume":"165","author":"Rowell","year":"1993","journal-title":"Am J Surg"},{"key":"10.3233\/BD-230007_ref3","doi-asserted-by":"crossref","first-page":"3020","DOI":"10.1002\/1097-0142(19930515)71:10<3020::AID-CNCR2820711022>3.0.CO;2-G","article-title":"The descriptive epidemiology of malignant cystosarcoma phyllodes tumors of the breast","volume":"71","author":"Bernstein","year":"1993","journal-title":"Cancer"},{"key":"10.3233\/BD-230007_ref4","doi-asserted-by":"crossref","first-page":"82","DOI":"10.1007\/BF02967630","article-title":"Phyllodes tumor arising in ectopic breast tissue of the axilla","volume":"10","author":"Oshida","year":"2003","journal-title":"Breast Cancer"},{"key":"10.3233\/BD-230007_ref5","volume-title":"Rosen\u2019s Breast Pathology","author":"Rosen","year":"2001"},{"key":"10.3233\/BD-230007_ref6","doi-asserted-by":"crossref","first-page":"723","DOI":"10.1053\/ejso.2001.1207","article-title":"Outcome and predictive factors of local recurrence and distant metastases following primary surgical treatment of high-grade malignant phyllodes tumors of the breast","volume":"27","author":"Kapiris","year":"2001","journal-title":"Eur J Surg Oncol"},{"key":"10.3233\/BD-230007_ref7","doi-asserted-by":"crossref","first-page":"454","DOI":"10.1136\/jcp.2005.025866","article-title":"Optimising preoperative diagnosis in phyllodes tumor of the breast","volume":"59","author":"Jacklin","year":"2006","journal-title":"J Clin Pathol"},{"key":"10.3233\/BD-230007_ref8","doi-asserted-by":"crossref","first-page":"793","DOI":"10.5999\/aps.2015.42.6.793","article-title":"Giant fibroadenoma in the axilla: A common entity of uncommon size in a rare location","volume":"42","author":"Seo","year":"2015","journal-title":"Arch Plast Surg"},{"key":"10.3233\/BD-230007_ref9","doi-asserted-by":"crossref","first-page":"153","DOI":"10.12659\/AJCR.892650","article-title":"Invasive mucinous carcinoma arising in ectopic axillary breast tissue: A case report and literature review","volume":"16","author":"Nardello","year":"2015","journal-title":"Am J Case Rep"},{"key":"10.3233\/BD-230007_ref10","first-page":"4071","article-title":"Clonal analysis of fibroadenoma and phyllodes tumor of the breast","volume":"53","author":"Noguchi","year":"1993","journal-title":"Cancer Res"},{"key":"10.3233\/BD-230007_ref11","unstructured":"WHO Classification of Breast Tumours. 5th ed., Vol 2.
