Unusual case of spindle cell sarcoma metastases to right ventricle: a case report and a literature review

The Heart of the Matter: A Unique Convergence of Cardiac Neoplasm, Hereditary Nonpolyposis Colorectal Cancer, and Spindle Cell Sarcoma

Primary cardiac tumours are exceedingly unusual and aggressive; they often develop in younger patients and present with advanced disease. The rarity and heterogeneity of primary cardiac tumours challenge the standardisation of therapeutic guidelines. Undifferentiated primary cardiac spindle cell sarcomas, a distinct subset of primary cardiac sarcomas, are especially unique with <20 cases reported worldwide, the majority of which are of left atrial origin. This article presents a review of the aetiology, pathophysiology, and therapy of undifferentiated primary cardiac spindle cell sarcomas. In conjunction, the authors present a unique case of a woman with hereditary nonpolyposis colorectal cancer (Lynch syndrome) who presented with a primary cardiac spindle cell sarcoma of left ventricular origin; this is the first case of this type and location of cardiac tumour reported in a patient with Lynch syndrome.

Electrocardiographic changes in right ventricular metastatic cardiac tumor mimicking acute ST elevation myocardial infarction: A case of misdiagnosis

INTRODUCTION

In patients with ST elevation myocardial infarction (STEMI), minimizing the reperfusion time is the goal of therapy worldwide. However, the differential diagnosis is critical and when a patient is encountered with chest pain and ST elevation, STEMI should not be the only diagnosis considered. By detailed history and focused physical examination, it is possible to avoid a mistaken diagnosis.

CASE PRESENTATION

In this report, we present a case of a male patient with tongue cancer and accompanying myocardial metastasis that causes electrocardiographic changes, who was initially misdiagnosed with ST elevation myocardial infarction.

CONCLUSION

Here, we reported a case of metastatic cancer in the heart which was initially diagnosed as acute myocardial infarction. Echocardiography, computed tomography and magnetic resonance imaging of the heart were used accordingly to confirm the myocardial metastasis.
