Bone metastasis of glandular cardiac myxoma mimicking a metastatic carcinoma.

Skeletal metastasis from a cardiac myxoma is rare. We describe an extremely unusual case of a cardiac myxoma metastasing to the femur in a 46-year-old female presenting with pain in the right hip. Radiographs showed an expansile lytic lesion with pathological fracture involving the neck and proximal shaft of the right femur. Histology revealed features of cardiac myxoma with heterologous glandular elements, which was initially mistaken for a metastatic mucin-secreting adenocarcinoma.
