As a result, many cases of benign thyroid enlargement caused by amyloid deposits remain undiagnosed. A 28-year-old male patient noticed progressive neck circumference enlargement, voice alteration, decreased appetite, weight loss, dysphagia, fever, and night sweats. Fine-needle aspiration biopsy of the thyroid gland did not reveal the cause of the goitre. A total thyroidectomy was performed. Histopathological examination confirmed advanced thyroid amyloidosis.<\/jats:p>","DOI":"10.3390\/jcm14196741","type":"journal-article","created":{"date-parts":[[2025,9,24]],"date-time":"2025-09-24T13:16:11Z","timestamp":1758719771000},"page":"6741","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Rare Case of Systemic Amyloidosis Involving the Thyroid in a Young Patient"],"prefix":"10.3390","volume":"14","author":[{"given":"Oliwia Julia","family":"Kasprzak","sequence":"first","affiliation":[{"name":"Surgical Scientific Society at the Department of General and Oncological Surgery, Pomeranian Medical University in Szczecin, 71-252 Szczecin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kamila","family":"St\u0119pi\u0144ska","sequence":"additional","affiliation":[{"name":"Surgical Scientific Society at the Department of General and Oncological Surgery, Pomeranian Medical University in Szczecin, 71-252 Szczecin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kaja","family":"Kiedrowska","sequence":"additional","affiliation":[{"name":"Surgical Scientific Society at the Department of General and Oncological Surgery, Pomeranian Medical University in Szczecin, 71-252 Szczecin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomasz","family":"B\u0142aszkowski","sequence":"additional","affiliation":[{"name":"Surgical Scientific Society at the Department of General and Oncological Surgery, Pomeranian Medical University in Szczecin, 71-252 Szczecin, Poland"},{"name":"Department of General and Oncological Surgery, Pomeranian Medical University in Szczecin, 71-252 Szczecin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aleksandra","family":"Kudrymska","sequence":"additional","affiliation":[{"name":"Department of Pathomorphology, Pomeranian Medical University in Szczecin, 71-252 Szczecin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sylwia","family":"Sikora","sequence":"additional","affiliation":[{"name":"Department of Pathomorphology, Pomeranian Medical University in Szczecin, 71-252 Szczecin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maciej","family":"Miernik","sequence":"additional","affiliation":[{"name":"Department of General and Oncological Surgery, Pomeranian Medical University in Szczecin, 71-252 Szczecin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7401-9877","authenticated-orcid":false,"given":"Maciej","family":"Romanowski","sequence":"additional","affiliation":[{"name":"Surgical Scientific Society at the Department of General and Oncological Surgery, Pomeranian Medical University in Szczecin, 71-252 Szczecin, Poland"},{"name":"Department of General and Oncological Surgery, Pomeranian Medical University in Szczecin, 71-252 Szczecin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,9,24]]},"reference":[{"doi-asserted-by":"crossref","unstructured":"Giorgetti, A., Pucci, A., and Aimo, A.
