Lipoma of the mitral valve in a child.
Echocardiographic examination, performed in an asymptomatic 5 year old boy for a perimembranous ventricular septal defect (VSD), revealed a 6 x 6 mm tumor on the anterior leaflet of the mitral valve. Clinically, it was diagnosed as a benign myxoma. Histopathologic diagnosis of the excised mitral valve tumor was benign lipoma. The third case of mitral valve lipoma in the pediatric age group is reported along with a review of the literature. Echocardiogram remains the most sensitive diagnostic modality in the early detection of such neoplasms.
