Though the breast lumps appeared suspicious on ultrasonography, the core biopsy was reported to be benign. In view of the clinical and radiological suspicion of malignancy, she underwent a diagnostic excision of both the lumps, the histopathology was consistent with mammary hibernoma. To the best of the authors\u2019 knowledge, this is the first report of a bilateral mammary hibernoma in an elderly postmenopausal woman. Given the clinical presentation, it is important to differentiate mammary hibernoma from carcinoma breast, which is a more common condition in this age group. However, preoperative diagnosis is challenging in view of the lack of definitive radiological and histological features. Although benign, hibernoma may have a propensity for local recurrence and, therefore, complete surgical excision remains the mainstay of treatment.<\/jats:p>","DOI":"10.1136\/bcr-2020-240552","type":"journal-article","created":{"date-parts":[[2021,3,22]],"date-time":"2021-03-22T13:11:21Z","timestamp":1616418681000},"page":"e240552","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Bilateral mammary hibernoma mimicking breast carcinoma: a diagnostic challenge"],"prefix":"10.1136","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1273-6712","authenticated-orcid":false,"given":"Royson","family":"Dsouza","sequence":"first","affiliation":[{"name":"General Surgery, Gudalur Adivasi Hospital, Nilgiris, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3649-8846","authenticated-orcid":false,"given":"Anish Jacob","family":"Cherian","sequence":"additional","affiliation":[{"name":"Endocrine Surgery, Christian Medical College and Hospital Vellore, Vellore, Tamil Nadu, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Radha","family":"Ananthakrishnan","sequence":"additional","affiliation":[{"name":"Laboratory Medicine and Pathology, G Kuppuswamy Naidu Memorial Hospital, Coimbatore, Tamil Nadu, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nandakumar","family":"Menon","sequence":"additional","affiliation":[{"name":"General Surgery, Gudalur Adivasi Hospital, Nilgiris, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,3,22]]},"reference":[{"key":"2025082800305922000_14.3.e240552.1","doi-asserted-by":"publisher","DOI":"10.1002\/ijc.25516"},{"key":"2025082800305922000_14.3.e240552.2","doi-asserted-by":"publisher","DOI":"10.4103\/2279-042X.132704"},{"key":"2025082800305922000_14.3.e240552.3","doi-asserted-by":"crossref","first-page":"16","DOI":"10.4103\/0019-509X.58853","article-title":"Profile of breast cancer patients at a tertiary care hospital in North India","volume":"47","author":"Sandhu","year":"2010","journal-title":"Indian J Cancer"},{"key":"2025082800305922000_14.3.e240552.4","unstructured":"Natural history of age-related lobular involution and impact on breast cancer risk.
