Synchronous triple cancers of synchronous endometrial and ovarian carcinoma complicated by renal cancer: a case report

This case report adds to the limited literature on synchronous triple primary malignancies. For synchronous endometrial and ovarian cancer, distinguishing between primary tumors and metastases is clinically critical. Notably, the presence of MMRd subtype in such synchronous tumors does not inherently indicate Lynch syndrome. This case underscores the importance of integrating molecular testing and clinical manifestations to accurately diagnose multiple primary malignancies and formulate tailored treatment plans.
