case_images: (A): Echocardiogram showed a mobile lobulated polypoid mass, originating from the anterior leaflet of the tricuspid valve. (B): Echocardiogram showed severe tricuspid regurgitation caused by the mass. (C): The tricuspid valve leaflet and chordae tendinae were eroded by the mass. (D): Part of the tricuspid valve and the mass were resected. (E): Anatomopathological examination of the tumor ( HE stained, original magnification x40). (F): Immunohistochemical examination of the tumor (original magnification x40).

case_images: During right ventricular systole, a portion of the mass prolapsed into the right atrium, obstructing the tricuspid orifice and leading to severe tricuspid regurgitation (Figure 1 Panel A and B). The leaflet and chordae tendinae were eroded by the mass (Figure 1 Panel C and D). Anatomopathological examination showed a rare, benign cardiac tumor: hemangioma (Figure 1 Panel E, HE stained, original magnification x40). Immunohistochemistry demonstrated lining cells in the tumor expressed CD34, desmin, and SMA (Figure 1 Panel F, original magnification x40).
