We report an extremely rare case of cystic-tumor like formations that originated from the mitral valve tissue affected by verrucous endocarditis, leading to floppy mitral valve syndrome. These cystic tumoral formations were discovered during two-dimensional echocardiographic examination of a 46 year-old woman with cardiac symptoms of palpitation, dyspnea, and exertional angina pectoris. Multiple cysts were attached to the anterior mitral leaflet, resulting in pansystolic pseudoparachute-like floppy mitral valve prolapse, and severe mitral regurgitation. The patient underwent prosthetic mitral valve replacement following removal of the mitral valve and multiple cystic-tumoral formations. She had an uneventful postoperative course. Histological diagnosis was diffuse angiomatous cystic development of vasculatory tumor- like structures due to verrucous endocarditis.
