From dyspnea to diagnosis, unmasking undifferentiated cardiac sarcoma: a case report.

backgroundSarcomas are the most common type of cardiac malignancy, but they are extremely rare. Within this group, angiosarcomas have the highest frequency, followed by undifferentiated sarcomas. This type of tumor has a poor prognosis and a high recurrence rate. Information about these tumors is limited, relying mainly on case reports and autopsy series. The purpose of this case report is to detail the multifaceted approach to diagnosing and managing an undifferentiated cardiac sarcoma and contribute to the literature. CASE PRESENTATION: A 28-year-old man presented with dyspnea and chest pain, which had developed progressively over several weeks. Physical examination revealed low blood pressure, elevated heart rate, and diminished heart sounds. Imaging, including a CT scan, identified a hypodense mass in the right ventricle. Further evaluation through echocardiograms and contrast angiotomography confirmed a mass causing right ventricular obstruction. Part of the tumor was surgically removed and diagnosed  as cardiac sarcoma.  Histopathological analysis of the mass showed an undifferentiated cardiac sarcoma.

conclusionThis case underscores the significance of including cardiac tumors as a potential cause when diagnosing cardiac masses. It also demonstrates the poor prognosis and tendency for recurrence, while revealing the absence of established management guidelines.
