EMP most frequently arises in the head and neck region, particularly within soft-tissue structures of the upper aerodigestive tract. Herein, we present a case report of a 31-year-old patient diagnosed with a localized extramedullary plasmacytoma (EMP) of the left palatine tonsil at the University Hospital in Krakow. We are also presenting a summary of the EMP of the tonsil case reports from the PubMed database. This article aims to present a clinical case of extramedullary plasmacytoma involving the palatine tonsil in a 31-year-old woman, with a detailed description of the diagnostic process and therapeutic management. In addition, the article reviews alternative diagnostic approaches and treatment modalities reported in the literature.<\/jats:p>","DOI":"10.36740\/merkur202601114","type":"journal-article","created":{"date-parts":[[2026,2,26]],"date-time":"2026-02-26T19:44:53Z","timestamp":1772135093000},"page":"89","source":"Crossref","is-referenced-by-count":0,"title":["Case report of extramedullary plasmacytoma within the left palatine tonsil in a 31-year-old female patient"],"prefix":"10.36740","volume":"54","author":[{"given":"Gabriela","family":"Kubicka","sequence":"first","affiliation":[{"name":"JAGIELLONIAN UNIVERSITY MEDICAL COLLEGE, CRACOW, POLAND"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wiktoria","family":"Soboci\u0144ska","sequence":"additional","affiliation":[{"name":"JAGIELLONIAN UNIVERSITY MEDICAL COLLEGE, CRACOW, POLAND"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcin","family":"Soboci\u0144ski","sequence":"additional","affiliation":[{"name":"DEPARTMENT OF HEMATOLOGY, UNIVERSITY HOSPITAL IN CRACOW, CRACOW, POLAND"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"\u0141ukasz","family":"Ko\u0142ody\u0144ski","sequence":"additional","affiliation":[{"name":"JAGIELLONIAN UNIVERSITY MEDICAL COLLEGE, CRACOW, POLAND"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"22436","published-online":{"date-parts":[[2026,2,15]]},"reference":[{"key":"ref0","doi-asserted-by":"crossref","unstructured":"1.
