Rhabdomyosarcoma from uterus to heart

Abstract

Rhabdomyosarcoma (RMS) is a malignant soft tissue tumor of the pediatric population which is (A) over cap rarely seen in adults. Metastatic rhabdomyosarcoma is even rarer. We present an unusual case of a 49 year old female presenting with palpitations and uterine bleeding. An Echo-cardiogram revealed a large oval mass on the posterior mitral leaflet and a Computerized Tomography (CT) scan of the abdomen revealed a uterine growth. Surgical excision of the cardiac mass was done and histological analysis of cardiac lesion confirmed it to be rhabdomyosarcoma with a primary source in the uterus. The patient became asymptomatic from a cardiac standpoint after excision of the mass and was scheduled for chemo/radiation therapy for the primary uterine malignancy. (A) over cap Metastatic cardiac rhabdomyosarcoma can be confused with a myxoma or any other primary or secondary cardiac tumors resulting in delayed diagnosis. However, its aggressive nature makes it a (A) over cap life-threatening tumor that requires an early diagnosis to prevent fatal consequences.
