Insights
A rare primary cardiac angiomyolipoma, a benign tumor typically found in the kidney, was surgically removed from a man's left ventricle. This case highlights a unique presentation of this uncommon heart tumor.
Area of Science:
- Cardiology
- Oncology
- Pathology
Background:
- Primary cardiac tumors are exceptionally rare, constituting only 0.3% of cardiac surgical procedures.
- Angiomyolipomas are typically benign tumors originating in the kidney, often associated with tuberous sclerosis.
Observation:
- A 39-year-old male presented with chest discomfort.
- Enhanced chest computed tomography revealed a mass within the left ventricular myocardium.
- Surgical resection of the intramyocardial tumor was performed under cardiopulmonary bypass.
Findings:
- Pathological examination identified a 4×3×3 cm, dome-shaped, solid tumor.
- Histopathological analysis confirmed the tumor as an angiomyolipoma, composed of vascular, smooth muscle, and adipose tissue.
- The patient showed no evidence of tuberous sclerosis.
Implications:
- This case represents a rare instance of primary cardiac angiomyolipoma, expanding the known locations for this tumor type.
- Surgical resection is a viable treatment for symptomatic cardiac angiomyolipomas.
- Further research may elucidate the specific mechanisms and associations of cardiac angiomyolipomas independent of tuberous sclerosis.
Abstract:
Primary tumors of the heart are rare. In the literature operations for heart tumors account for 0.3% of all cardiac surgical procedures. We report a very rare case of primary cardiac angiomyolipoma. A 39-years-old man was admitted with chest discomfort. A mass was detected in the left ventricular myocardium by enhanced chest computed tomography. We performed resection of the intramyocardial tumor under cardiopulmonary bypass. Pathologic examination revealed a 4×3×3 cm, dome-shaped, solid tumor composed of a mixture of blood vessels, smooth muscle, and fat tissue. Histopathological findings showed that the tumor was angiomyolipoma. Angiomyolipoma is a benign tumor and usually develop in the kidney and are associated with tuberous sclerosis. In our case, there was no evidence of tuberous sclerosis.
