Trousseau syndrome (TS)–related nonbacterial thrombotic endocarditis (NBTE) caused by ovarian cancer has rarely been reported. Although primary tumors and cardiac lesions can be treated surgically, there has been a rising concern regarding the use of anticoagulants in the treatment of TS.
The clinical data and course of Trousseau syndrome‐related NBTE in a case of mucinous ovarian carcinoma treated in Shenzhen People's Hospital in 2023 were retrospectively analyzed, and the relevant literature was reviewed.
We report a rare case of Trousseau syndrome‐related nonbacterial thrombotic endocarditis attributable to mucinous ovarian carcinoma. Timely and accurate diagnosis and treatment can improve the prognosis.
