Previously, she was first diagnosed with a FA and received excision in 2016. The initial clinical presentation was a palpable mass in the left breast. During periodic breast ultrasound examination in 2020, another newly developed tumor was found in the same region. A core biopsy revealed a fibroepithelial lesion. The patient received wide excision surgery. The final pathology report indicated a phyllodes tumor (PT) with a clear margin. All three events occurred in the same region (left breast, at 2 O\u2019clock and 3\u20135 cm from the nipple). Our patient had a relapsed FA, which progressed into a benign PT and FA concomitant with DCIS and multifocal mucinous carcinomas. We report this case to highlight the need for continuous follow-up for FA cases even after complete resection and the possibility of recurrence with other fibroepithelial tumors.\n                  <\/jats:p>","DOI":"10.4103\/jmu.jmu_93_24","type":"journal-article","created":{"date-parts":[[2025,6,11]],"date-time":"2025-06-11T06:00:07Z","timestamp":1749621607000},"page":"390-393","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Recurrent Fibroadenoma and Concomitant Mucinous Cancer with Ductal Carcinoma In situ Following Benign Phyllodes Tumor Excision: A Rare Case Report"],"prefix":"10.4103","volume":"33","author":[{"given":"Pei-Shyuan","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Family and Community Medicine, Cathay General Hospital, Taipei, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ming-Lin","family":"Tsai","sequence":"additional","affiliation":[{"name":"Department of Breast Surgery, Cathay General Hospital, Taipei, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu-Chi","family":"Chang","sequence":"additional","affiliation":[{"name":"Department of Family and Community Medicine, Cathay General Hospital, Taipei, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shing-Huey","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Family and Community Medicine, Cathay General Hospital, Taipei, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2025,6,11]]},"reference":[{"key":"R1-20260805","doi-asserted-by":"crossref","first-page":"297","DOI":"10.1023\/A:1008263522021","article-title":"Risk of breast cancer subsequent to histological or clinical diagnosis of fibroadenoma \u2013Retrospective longitudinal study of 3938 cases","volume":"8","author":"Ciatto","year":"1997","journal-title":"Ann Oncol"},{"key":"R2-20260805","doi-asserted-by":"crossref","first-page":"572","DOI":"10.1016\/j.ygyno.2004.04.031","article-title":"Lobular carcinoma in situ of the breast within a fibroadenoma.
