Although secondary ITP, caused by various underlying diseases, including some malignant tumors, has been reported, instances of ITP resolving after successful treatment of the underlying cause are uncommon and noteworthy. Herein, we present a case of a patient with perihilar cholangiocarcinoma (pCCA) and ITP who achieved drug-free remission of ITP following tumor resection. A 76-year-old man presented with pCCA complicated by ITP. Prednisolone treatment successfully managed his thrombocytopenia, allowing for a left hepatopancreatoduodenectomy. ITP relapse did not occur after discontinuation of prednisolone postoperatively. This case suggests that surgical resection of the underlying malignancy may induce remission of secondary ITP associated with pCCA.<\/jats:p>","DOI":"10.1093\/jscr\/rjae607","type":"journal-article","created":{"date-parts":[[2024,9,27]],"date-time":"2024-09-27T02:46:57Z","timestamp":1727405217000},"source":"Crossref","is-referenced-by-count":0,"title":["Drug-free
