Insights
This case report details a rare primary cardiac malignant fibrous histiocytoma in a 74-year-old female. Despite successful surgery, the patient succumbed to disseminated intravascular coagulation (DIC).
Area of Science:
- Cardiology
- Oncology
- Pathology
Background:
- Primary cardiac tumors are rare, with malignant fibrous histiocytoma being an exceptionally uncommon diagnosis.
- This report presents the 40th documented case of primary cardiac malignant fibrous histiocytoma.
Observation:
- A 74-year-old female presented with heart failure refractory to medical management.
- Echocardiography identified two left atrial tumors, one significantly obstructing mitral valve inflow.
Findings:
- Surgical resection of the cardiac tumors was performed emergently and successfully.
- Pathological examination confirmed the diagnosis of malignant fibrous histiocytoma.
- The patient developed disseminated intravascular coagulation (DIC) post-operatively, leading to mortality on day 24.
Implications:
- Highlights the diagnostic challenges and aggressive nature of primary cardiac malignant fibrous histiocytoma.
- Underscores the importance of prompt surgical intervention for symptomatic cardiac tumors.
- Emphasizes the potential for severe post-operative complications, including DIC, in such cases.
Abstract:
In this article, we report a case of primary cardiac malignant fibrous histiocytoma. The patient, 74-year-old female, had been treated medically for heart failure with minimal improvement and was referred to our hospital. Echocardiogram revealed two cardiac tumors in the left atrium, one of which was obstructing the inflow of the mitral valve. Emergent surgical resection was performed successfully with shortterm ICU stay, but the patient died of DIC on the 24th day after surgery. The pathological examination revealed malignant fibrous histiocytoma and this report is the 40th case report of this kind of primary cardiac tumor.
