Key result
Complete resection of a primary epithelioid hemangioendothelioma of the right atrium in a 77-year-old woman resulted in no recurrence or metastasis at 4 years post-operation.
Case Report (n=1)
Primary cardiac epithelioid hemangioendothelioma is an extremely rare vascular tumor with malignant potential that can be successfully managed with surgical resection, though long-term follow-up is necessary.
Supports resection feasibility in rare right atrial epithelioid hemangioendothelioma; leaves open generalizability and optimal management in larger cohorts.
Primary cardiac epithelioid hemangioendothelioma (EHE) is extremely uncommon. To our knowledge, only fourteen cases have been reported. We report a case of a primary EHE of the right atrium which incidentally detected in 77-year-old woman. Echocardiograhpy revealed a 26 × 16 mm right atrial mass attached to the base of the interatrial septum and moderate regurgitation of the tricuspid valve. The tumor and stalk were completely resected from the interatrial septum with a partial resection of the septal leaflet of the tricuspid valve. The patient had an uneventful postoperative course and no signs of recurrence nor metastasis of EHE 4 years after operation. Because of malignant potential of EHE, a longer period of close follow up is necessary.

Sugimoto et al. (2013) conducted a case report in Primary cardiac epithelioid hemangioendothelioma (EHE) of the right atrium (n=1). Complete resection of the tumor and stalk with partial resection of the septal leaflet of the tricuspid valve was evaluated on Recurrence or metastasis. Complete resection of a primary epithelioid hemangioendothelioma of the right atrium in a 77-year-old woman resulted in no recurrence or metastasis at 4 years post-operation.
