Background:
Primary cardiac sarcomas are quite uncommon. Among them, sarcomas originating from the mitral valve are exceedingly rare. They are often misdiagnosed due to non-specific symptoms. The prognosis of cardiac sarcomas remains poor, and finding a more effective therapy poses a big challenge for the doctors. Currently, complete surgical resection of the tumor is still the most popular treatment in cases that without metastases.
Case Presentation:
A 38-year-old female was transported to our department with persistent cough and chest pain. The operation of mitral valve replacement was scheduled after a provisional diagnosis of serious mitral stenosis. During the operation, we found that a large polypoid mass infiltrating mainly the mitral valve and part of the left atria. We removed the tumor as completely as possible and replaced the mitral valve. Histology confirmed the diagnosis of undifferentiated sarcoma after operation. The patient was asymptomatic with no recurrence at 3-month follow-up.
Conclusion:
Primary cardiac sarcomas is a rare and the prognosis is poor. The sarcomas is often found by chance during the operation. Surgical operation need to be carried out directly.
Insights
Primary cardiac sarcomas, especially those on the mitral valve, are rare and difficult to diagnose. Complete surgical removal offers the best treatment option for this challenging condition.
Area of Science:
- Cardiovascular Pathology
- Surgical Oncology
Background:
- Primary cardiac sarcomas are rare malignancies.
- Mitral valve sarcomas are exceptionally uncommon, often presenting with non-specific symptoms leading to misdiagnosis.
- The prognosis for cardiac sarcomas is generally poor, highlighting the need for effective therapeutic strategies.
Observation:
- A 38-year-old female presented with persistent cough and chest pain, initially diagnosed with mitral stenosis.
- Intraoperative findings revealed a large polypoid mass infiltrating the mitral valve and left atrium.
- The mass was surgically resected, and mitral valve replacement was performed.
Findings:
- Histological examination confirmed the resected mass as an undifferentiated sarcoma.
- The patient remained asymptomatic with no evidence of recurrence at the 3-month follow-up.
Implications:
- This case underscores the importance of considering rare cardiac tumors in the differential diagnosis.
- Complete surgical resection is a critical intervention for primary cardiac sarcomas.
- Early detection and surgical management are crucial for improving patient outcomes in these rare cases.
