Despite the fact that the epidemiologic, clinical, and therapeutic literature regarding female breast cancer is well documented, little is known about the features of male breast cancer. Here, we present a case of cytological pleural metastasis from ductal breast carcinoma in a 55\u2010year\u2010old man. Immunohistochemical staining showed that the tumor cells were positive for BerEp4, GATA\u20103, AE1\/AE3, CAM5.2, ER (70%), AR (10%), PR (10%), and ki67 (10%). In our experience, effusion cytology remains an accurate tool for the diagnosis of metastatic carcinomas.<\/jats:p>","DOI":"10.1002\/dc.70049","type":"journal-article","created":{"date-parts":[[2025,11,15]],"date-time":"2025-11-15T12:01:17Z","timestamp":1763208077000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Pleural Metastasis From Male Breast Cancer: A Case Report"],"prefix":"10.1002","volume":"54","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-1079-8390","authenticated-orcid":false,"given":"Patrizia","family":"Straccia","sequence":"first","affiliation":[{"name":"Division of Anatomic Pathology and Histology Catholic University of Sacred Heart, Foundation \u201cAgostino Gemelli\u201d University Hospital  Rome Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Esther Diana","family":"Rossi","sequence":"additional","affiliation":[{"name":"Division of Anatomic Pathology and Histology Catholic University of Sacred Heart, Foundation \u201cAgostino Gemelli\u201d University Hospital  Rome Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,11,15]]},"reference":[{"key":"e_1_2_8_2_1","first-page":"1975","article-title":"CA Cancer J.
