This report describes a young female patient who was initially diagnosed with bilateral breast fibroadenoma. Postoperative pathological examination revealed coexisting bilateral mammary fibroadenomas with DCIS. While mammary fibroadenomas are common benign lesions, their coexistence with DCIS often leads to missed diagnoses, potentially resulting in serious consequences. This case study highlights the importance of enhancing clinicians' understanding of breast lesion complexity and optimizing diagnostic and therapeutic protocols.<\/jats:p>","DOI":"10.1002\/ccr3.71794","type":"journal-article","created":{"date-parts":[[2026,1,6]],"date-time":"2026-01-06T16:02:38Z","timestamp":1767715358000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Bilateral Breast Fibroadenoma With Bilateral Ductal Carcinoma In\u00a0Situ: A Case Report"],"prefix":"10.1002","volume":"14","author":[{"given":"Siyang","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Breast and Thyroid Surgery, Daping Hospital Army Military Medical University  Chongqing China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaohua","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Breast and Thyroid Surgery, Daping Hospital Army Military Medical University  Chongqing China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6414-6808","authenticated-orcid":false,"given":"Wuguo","family":"Tian","sequence":"additional","affiliation":[{"name":"Department of Breast and Thyroid Surgery, Daping Hospital Army Military Medical University  Chongqing China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2026,1,6]]},"reference":[{"key":"e_1_2_13_2_1","first-page":"127","article-title":"Management of Fibroadenoma of the Breast","volume":"77","author":"Carty N.
