His laboratory findings were significant for hyperprolactinaemia at 28\u2009ng\/mL. Diagnostic work up including mammography, ultrasound and core needle biopsy ultimately revealed a ductal carcinoma in situ and a rare papillary variant of invasive ductal carcinoma. The patient was referred to a multidisciplinary oncology team and underwent a right total mastectomy followed by adjuvant hormonal therapy. The patient made a good postoperative recovery and remains without evidence of recurrence 6 months from surgery. Male breast cancer is rare, but its incidence is increasing. Male breast cancer presenting as ND without a palpable mass is uncommon. Early recognition of breast symptoms in men can lead to earlier diagnoses and improved outcomes.<\/jats:p>","DOI":"10.1136\/bcr-2020-236223","type":"journal-article","created":{"date-parts":[[2020,11,30]],"date-time":"2020-11-30T15:46:05Z","timestamp":1606751165000},"page":"e236223","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Unilateral nipple discharge in a man without a palpable mass diagnosed as breast cancer"],"prefix":"10.1136","volume":"13","author":[{"given":"Karan N","family":"Ramakrishna","sequence":"first","affiliation":[{"name":"Department of Internal Medicine, SUNY Upstate Medical University, Syracuse, New York, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Justin","family":"Durland","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, SUNY Upstate Medical University, Syracuse, New York, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christopher","family":"Ramos","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, SUNY Upstate Medical University, Syracuse, New York, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amit Singh","family":"Dhamoon","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, SUNY Upstate Medical University, Syracuse, New York, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2020,11,30]]},"reference":[{"key":"2025082711403789000_13.11.e236223.1","unstructured":"American Cancer Society .
