Trousseau’s Syndrome and Marantic Endocarditis in a Patient with Pulmonary Adenocarcinoma: A Case Report and Review of Literature

Background: Trousseau’s syndrome, characterized by recurrent thromboembolic events and non-bacterial thrombotic endocarditis, represents a severe paraneoplastic condition associated with poor prognosis in cancer patients. Methods: We describe a case of a 63-year-old male presenting with ischemic stroke and mitral valve marantic endocarditis, ultimately diagnosed with pulmonary adeno-carcinoma. The case description is followed by a brief review of the current literature on the condition. Discussion and Conclusion: This case highlights the complexity of diagnosing and managing Trousseau’s syndrome. Early recognition, appropriate anti-coagulation strategies, and the need for multidisciplinary management are crucial to improve the outcomes and the quality of life of cancer patients.
