Insights
A rare malignant hemangioendothelioma cardiac tumor was found in a 32-year-old man. Surgical resection was successful, highlighting the rarity of this cardiac tumor in Japan.
Area of Science:
- Cardiology
- Oncology
- Pathology
Background:
- Cardiac tumors are rare, with malignant primary tumors being even rarer.
- Malignant hemangioendothelioma is an uncommon vascular tumor with a propensity for cardiac involvement.
- Few cases of cardiac malignant hemangioendothelioma have been reported globally, particularly in Japan.
Abstract:
A 32-year-old man was admitted to our hospital because a cardiac tumor had been pointed out by a physician. CT scans showed a mass lesion with irregular patterns in the right atrium. The patient had the diagnosis of a malignant cardiac or pericardial tumor and an operation was performed. The mass originated from the right atrium included massive coagulated blood, and was resected with the pericardium and the right pleura. The histological diagnosis was malignant hemangioendothelioma. We present this case because only 35 patients with cardiac malignant hemangioendothelioma were reported in Japan.
