Seventy-one cytologic specimens were studied; 52 were carcinomas, 15 fibroadenomas and 4 fibrocystic dysplasia. TPA was visualized with the peroxidaseantiperoxidase method, using 3-3 \u2018diaminobenzidine as chromogen and hematoxylin as counterstaining. The incidence of TPA-positive aspiration smears was 88.5% in the carcinomas and 26.7% in the fibroadenomas. The four cases of fibrocystic dysplasia showed variable behaviour. The intensity of the TPA staining varied from \u2013 to + + + and was most frequently high in the carcinomas. The results of this research show a good correlation between a diagnosis of carcinoma and TPA positivity in fine needle aspirates of solid breast nodules.<\/jats:p>","DOI":"10.1177\/172460089300800206","type":"journal-article","created":{"date-parts":[[2018,4,16]],"date-time":"2018-04-16T10:15:05Z","timestamp":1523873705000},"page":"103-107","source":"Crossref","is-referenced-by-count":0,"title":["Tissue Polypeptide Antigen Immunostaining in Fine Needle Aspirates from Solid Breast Nodules"],"prefix":"10.1177","volume":"8","author":[{"given":"S.","family":"Battistelli","sequence":"first","affiliation":[{"name":"Institute of Histology and Laboratory Analysis, University of Urbino, Urbino"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"F.","family":"Marcheggiani","sequence":"additional","affiliation":[{"name":"Institute of Histology and Laboratory Analysis, University of Urbino, Urbino"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"I.","family":"Pecorella","sequence":"additional","affiliation":[{"name":"Department of Human Biopathology, Section of Pathologic Anatomy, \u201cLa Sapienza\u201d University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Sessa","sequence":"additional","affiliation":[{"name":"Center for Cancer Prevention and Diagnosis, USL RM1"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Malatesta","sequence":"additional","affiliation":[{"name":"Institute of Histology and Laboratory Analysis, University of Urbino, Urbino"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G.","family":"Ligori","sequence":"additional","affiliation":[{"name":"Center for Cancer Prevention and Diagnosis, USL RM1"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R.","family":"Troccoli","sequence":"additional","affiliation":[{"name":"Department of Human Anatomy, \u201cLa Sapienza\u201d University, Roma -
