Their histologic appearance is due to excessive amounts of cytoplasmic mitochondria. Oncocytes generally occur in the setting of benign neoplasms. Oncocytomas, or tumors composed primarily of oncocytes, are typically found in the kidneys. Other common sites include the salivary, thyroid, and parathyroid glands. Oncocytic metaplasia has only been rarely reported in various cutaneous neoplasms. We report a case of an elderly male presenting with a 5\u2009mm erythematous papule on his left scalp, who underwent a shave biopsy showing a nodular, dermal\u2010based adnexal tumor with prominent ductal differentiation, composed of multiple small, well\u2010formed lumina surrounded by enlarged and bland\u2010appearing epithelioid cells. Cytokeratin 7 (<jats:styled-content style=\"fixed-case\">CK7<\/jats:styled-content>), epithelial membrane antigen (EMA) and monoclonal carcinoembryonic antigen (mCEA) immunohistochemical stains were positive, consistent with adnexal differentiation. Phosphotungstic acid\u2010hematoxylin (PTAH) and Luxol fast blue (LFB) stains highlighted the cytoplasmic granules, consistent with mitochondria. The overall findings were consistent with an oncocytic nodular hidradenoma. Oncocytic hidradenoma is a very rare entity, with only 1 previously reported case in the literature.<\/jats:p>","DOI":"10.1111\/cup.12883","type":"journal-article","created":{"date-parts":[[2016,12,30]],"date-time":"2016-12-30T05:46:40Z","timestamp":1483076800000},"page":"289-291","source":"Crossref","is-referenced-by-count":5,"title":["A rare case of cutaneous oncocytic hidradenoma"],"prefix":"10.1111","volume":"44","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3295-8021","authenticated-orcid":false,"given":"Shivani P.","family":"Reddy","sequence":"first","affiliation":[{"name":"School of Medicine University of Illinois at Chicago College of Medicine  Chicago Illinois"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kim","family":"Chong","sequence":"additional","affiliation":[{"name":"Departments of Dermatology and Pathology Kaiser Permanente Los Angeles Medical Center  Los Angeles California"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8875-0858","authenticated-orcid":false,"given":"David S.","family":"Cassarino","sequence":"additional","affiliation":[{"name":"Departments of Dermatology and Pathology Kaiser Permanente Los Angeles Medical Center  Los Angeles California"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2017,2,2]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/00000372-199606000-00013"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0560.2006.00620.x"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/cup.12223"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/cup.12647"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1097\/00000372-200212000-00002"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.1177\/112067219100100405"},{"issue":"2","key":"e_1_2_5_8_1","first-page":"162","article-title":"Tumors of the skin composed of large cells with abundant eosinophilic cytoplasm","volume":"16","author":"Suster S","year":"1999","journal-title":"Semin Diagn Pathol"},{"key":"e_1_2_5_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(196209\/10)15:5<1019::AID-CNCR2820150519>3.0.CO;2-5"},{"key":"e_1_2_5_10_1","first-page":"263","article-title":"Oncocytes, oncocytosis, and oncocytic tumors","volume":"27","author":"Chang A","year":"1992","journal-title":"Pathol Annu"},{"key":"e_1_2_5_11_1","doi-asserted-by":"publisher","DOI":"10.1055\/s-2004-814267"}],"container-title":["Journal of Cutaneous Pathology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fcup.12883","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/cup.12883","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,3]],"date-time":"2023-10-03T18:12:01Z","timestamp":1696356721000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/cup.12883"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,2,2]]},"references-count":10,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2017,3]]}},"alternative-id":["10.1111\/cup.12883"],"URL":"https:\/\/doi.org\/10.1111\/cup.12883","archive":["Portico"],"relation":{},"ISSN":["0303-6987","1600-0560"],"issn-type":[{"value":"0303-6987","type":"print"},{"value":"1600-0560","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017,2,2]]}}}
