No significant differences between CD20 and CD3 lymphocytes were found in peri-epithelial areas. However, there were more intra-ductal\/lobular epithelial CD3 than CD20 lymphocytes (p&lt;0.001). For T lymphocyte subsets, more CD4 than CD8 lymphocytes were found in the peri-lobular\/vascular regions (p\u22640.026); but an opposite trend was seen in the intra-ductal\/lobular regions (p&lt;0.001). In the peri-lobular\/vascular regions, generally, different lymphocyte subsets correlated with each other. Interestingly, in the peri-ductal region, only CD4 lymphocytes showed significant correlations with all other subsets (p\u22640.020). Regarding their relationship with the degree of inflammation, significant positive correlations were observed for all subsets in peri-vascular\/lobular regions (p\u22640.045). Only regulatory T cells, but not the others, at the peri-ductal region showed significant correlation with the degree of inflammation at all three regions (p\u22640.014).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>In addition to B lymphocyte subsets, T lymphocyte subsets could be involved differently in SLL. CD4 lymphocytes may have a pivotal role in recruiting other subsets to the inflamed site, and triggered the cascade of inflammatory changes resulting in fibrosis.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1136\/jclinpath-2015-203334","type":"journal-article","created":{"date-parts":[[2015,11,18]],"date-time":"2015-11-18T22:43:46Z","timestamp":1447886626000},"page":"527-532","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":6,"title":["Lymphocyte subsets contribute to the degree of lobulitis and ductitis in sclerosing lymphocytic lobulitis of the breast"],"prefix":"10.1136","volume":"69","author":[{"given":"Lin-Ying","family":"Chen","sequence":"first","affiliation":[{"name":"Department of Pathology, The First Affiliated Hospital of Fujian Medical University, Fuzhou, Fujian, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julia Y S","family":"Tsang","sequence":"additional","affiliation":[{"name":"Department of Anatomical and Cellular Pathology, Prince of Wales Hospital, The Chinese University of Hong Kong, Shatin, NT, Hong Kong"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yun-Bi","family":"Ni","sequence":"additional","affiliation":[{"name":"Department of Anatomical and Cellular Pathology, Prince of Wales Hospital, The Chinese University of Hong Kong, Shatin, NT, Hong Kong"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Siu-Ki","family":"Chan","sequence":"additional","affiliation":[{"name":"Department of Pathology, Kwong Wah Hospital, Hong Kong, Hong Kong"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kui-Fat","family":"Chan","sequence":"additional","affiliation":[{"name":"Department of Pathology, Tuen Mun Hospital, Hong Kong, Hong Kong"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sheng","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Pathology, The First Affiliated Hospital of Fujian Medical University, Fuzhou, Fujian, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gary M","family":"Tse","sequence":"additional","affiliation":[{"name":"Department of Anatomical and Cellular Pathology, Prince of Wales Hospital, The Chinese University of Hong Kong, Shatin, NT, Hong Kong"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2015,11,18]]},"reference":[{"key":"2025092503240404000_69.6.527.1","first-page":"49","article-title":"Lymphocytic mastitis and fibrosis of the breast in long-standing insulin-dependent diabetics.
