Existing descriptions have largely focused on well\u2010developed lesions, leaving the histopathologic features of smaller, localized lesions poorly characterized. We report an attenuated OM in a 45\u2010year\u2010old woman highlighting subtle but characteristic histopathologic features of OM, including a focal CD34\u2010positive spindle cell population in the superficial submatrical dermis, matrical epithelial papillation, and focal serum\u2010filled cavity formation within the nail plate. Compared with classic OM, these findings were more localized and less architecturally developed, while still retaining key diagnostic features. Improved recognition of these subtle features in attenuated lesions will facilitate earlier diagnosis, reduce misclassification, and refine clinicopathologic criteria for this important nail unit tumor.<\/jats:p>","DOI":"10.1111\/cup.70223","type":"journal-article","created":{"date-parts":[[2026,10,6]],"date-time":"2026-10-06T04:29:57Z","timestamp":1791260997000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Histopathologic Features of an Attenuated Onychomatricoma: A Novel Variant"],"prefix":"10.1111","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6075-4475","authenticated-orcid":false,"given":"Archie","family":"Spindler","sequence":"first","affiliation":[{"name":"The Ronald O.
