Cardiac metastasis from gastric adenocarcinoma: A rare case report.

Introduction And Significance: Cardiac dissemination of gastric adenocarcinoma represents an exceedingly uncommon clinical scenario. To date, there is an absence of documentation concerning the presence of tumor emboli within the cardiac chambers originating from gastric cancer, particularly following a possible transvenous migration.

Case Presentation: This report delineates the clinical journey of a 60-year-old female diagnosed with inoperable diffuse gastric adenocarcinoma, who developed cardiac metastases.

Clinical Discussion: The prognostication of isolated cardiac metastasis in oncology patients is fraught with difficulty due to its infrequency and non-specific clinical manifestations. While systematic screening for cardiac metastasis is not part of standard oncological protocols, heightened vigilance is warranted in specific scenarios such as advanced-stage malignancies or in the presence of suggestive cardiac symptomatology, thereby prompting further exploration.

Conclusion: Cardiac metastasis, while infrequent, constitutes a dire clinical entity that must be contemplated in the differential diagnosis of cardiac mass presentations in individuals with a neoplastic history. Prompt recognition and deployment of appropriate diagnostic imaging are pivotal for informed therapeutic decision-making. An integrative, multidisciplinary strategy is imperative for the formulation of an optimal treatment paradigm, encompassing surgical and palliative care options.

Key Clinical Message: Cardiac metastasis of gastric adenocarcinoma are extremely rare, however, in gastric cancer cases with cardiopulmonary manifestation should be considered as a probable differential diagnoses.
