Proximally, there are serum-filled invaginations of nail matrix epithelium into the stroma, and distally, dermal protrusions perforate the nail plate. Because other matrical tumors of follicular and odontogenic origin express nuclear \u03b2-catenin, we examined the expression of cadherin\/catenin proteins in this onychomatricoma case. The patient presented with a toenail yellow streak, and the biopsy revealed an onychomatricoma. E-cadherin and \u03b2-catenin were at the cell membrane in the epithelial invaginations. P-cadherin was restricted to basal cells. In contrast to other matrical tumors, nuclear \u03b2-catenin was not present. These results suggest that onychomatricoma may lack the transcriptional activating role of \u03b2-catenin that characterizes follicular and odontogenic matrical tumors. This is the first report on the expression of cadherin\/ catenin cell\u2014cell adhesion proteins in this rare nail tumor.<\/jats:p>","DOI":"10.1177\/1066896907310374","type":"journal-article","created":{"date-parts":[[2008,6,23]],"date-time":"2008-06-23T02:17:37Z","timestamp":1214187457000},"page":"349-353","source":"Crossref","is-referenced-by-count":11,"title":["Expression
