Studies dedicated to plurihormonal tumours are rare and quite heterogenous with their results, bearing in mind changes in diagnostic criteria and inconsistent use of antibodies for anterior pituitary transcription factors in the diagnostic immunohistochemical panel.\n                    <jats:italic toggle=\"yes\">Material and Methods.<\/jats:italic>\n                    We retrospectively analysed all patients surgically treated for PitNETs from 2016 to July 2022 in a tertiary healthcare institution. All tumours previously diagnosed PitNETs with the word \u201cplurihormonal\u201d were re-examined and potentially re-classified, according to 2022 WHO classification of endocrine tumours.\n                    <jats:italic toggle=\"yes\">Results.<\/jats:italic>\n                    Among 721 patients surgically treated for PitNET in 5.5 years period, the diagnosis of plurihormonal PitNET was established in 11 tumours (1.3%). All tumours showed diffuse and intensive positivity for anterior pituitary transcription factors PIT1 and SF1. Clinically, all patients presented with acromegaly.\n                    <jats:italic toggle=\"yes\">Conclusions.<\/jats:italic>\n                    Retrospective studies related to newly defined plurihormonal PitNETs with a reassessment of diagnoses are necessary due to their rarity and ambition to investigate their origin and biological behaviour. The fact that the majority of plurihormonal PitNETs are clinically presented with acromegaly and show simultaneous positivity to PIT1 and SF1 transcription factors deserve special attention and need for further research in larger cohorts of these exceptional tumours.\n                  <\/jats:p>","DOI":"10.1177\/10668969231183712","type":"journal-article","created":{"date-parts":[[2023,7,13]],"date-time":"2023-07-13T01:54:28Z","timestamp":1689213268000},"page":"470-477","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":7,"title":["Plurihormonal Pituitary Neuroendocrine Tumours \u2013 A Single Centre Experience"],"prefix":"10.1177","volume":"32","author":[{"given":"Milena","family":"Mihajlovi\u0107","sequence":"first","affiliation":[{"name":"University Clinical Center of Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sandra","family":"Peki\u0107","sequence":"additional","affiliation":[{"name":"University Clinical Center of Serbia"},{"name":"Faculty of Medicine, University of Belgrade"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mirjana","family":"Dokni\u0107","sequence":"additional","affiliation":[{"name":"University Clinical Center of Serbia"},{"name":"Faculty of Medicine, University of Belgrade"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marko","family":"Stojanovi\u0107","sequence":"additional","affiliation":[{"name":"University Clinical Center of Serbia"},{"name":"Faculty of Medicine, University of Belgrade"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dejan","family":"Ra\u0161i\u0107","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, University of Belgrade"},{"name":"University Clinical Center of Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dragana","family":"Milji\u0107","sequence":"additional","affiliation":[{"name":"University Clinical Center of Serbia"},{"name":"Faculty of Medicine, University of Belgrade"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Milan","family":"Petakov","sequence":"additional","affiliation":[{"name":"University Clinical Center of Serbia"},{"name":"Faculty of Medicine, University of Belgrade"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emilija","family":"Manojlovi\u0107 Ga\u010di\u0107","sequence":"additional","affiliation":[{"name":"Institute of Pathology, Faculty of Medicine, University of Belgrade, Belgrade, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2023,7,12]]},"reference":[{"key":"e_1_3_3_2_2","unstructured":"WHO Classification of Tumours Editorial Board WHO classification of tumours of endocrine organs 5th edn.
