From his physical examination, microscopy of a blood smear, and what was then known about the life cycle of platelets, he concluded that his patient\u2019s bleeding diathesis and enlarged spleen were linked: she had no platelets because they were being destroyed by the organ. He convinced the chief of surgery to remove the patient\u2019s spleen, a landmark operation that succeeded beyond \u201cthe wildest expectations\u201d. He stayed on faculty, but his promising academic career was derailed by virulent antisemitism, first in his own university medical school, then his home country. Forced into exile in 1939 he found refuge in the United Kingdom, which allowed him to practice medicine but denied him formal residency. At war\u2019s end he found himself unwanted in the West by his Russian heritage and citizenship in an Iron Curtain country. Czechoslovakia\u2019s newly installed communist regime barred his repatriation due to the ambiguous circumstances of his wartime residency in England. Today treatment of ITP is directed toward controlling autoimmune reaction against platelet antigens. Splenectomy is done only after nonsurgical options have been exhausted. The operation and its history are a fading coda to the story of a medical prodigy whose career was crushed by prejudice and world events.<\/jats:p>","DOI":"10.1177\/00031348251363850","type":"journal-article","created":{"date-parts":[[2025,7,28]],"date-time":"2025-07-28T04:14:31Z","timestamp":1753676071000},"page":"307-310","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Paul Kaznelson, Immune Thrombocytopenic Purpura, and Splenectomy: The Tragic Story of a Medical Prodigy"],"prefix":"10.1177","volume":"92","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-9324-9031","authenticated-orcid":false,"given":"Don K.","family":"Nakayama","sequence":"first","affiliation":[{"name":"Mercer University School of Medicine"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2025,7,27]]},"reference":[{"issue":"18","key":"e_1_3_3_2_2","first-page":"454","article-title":"Die essentielle Thrombopenies (konstitutionelle Psuedohaemophilie)","volume":"52","author":"Frank E","year":"1915","unstructured":"Frank E.
