Key result
Rare composite hemangioendothelioma can present as a calcified cardiac mass mimicking right atrial myxoma.
Why the study?
Composite hemangioendothelioma is a rare vascular tumor typically found in dermis and subcutaneous tissue, with rare cardiac involvement.
Highlights a rare presentation of composite hemangioendothelioma in the heart mimicking a right atrial myxoma.
Composite hemangioendothelioma (CHE) is a rare vascular tumor which shows varying combination of benign, low-grade, and malignant vascular components on pathology. CHE is usually located on the surface of the dermis and subcutaneous tissue of the extremities. We report an unusual case of CHE in the heart.
