Abstract

Carcinoma of the uterine cervix with cardiac metastasis is not uncommon in autopsy cases. However, an intraatrial tumor extending through the inferior vena cava (IVC) from the site of para-aortic lymph node metastasis has never been reported. A 57-year-old Japanese woman was admitted to an emergency care unit complaining of mild chest pain and shortness of breath. She had progressive multiple lymphatic metastases of stage IIIB squamous cell carcinoma of the uterine cervix that had initially been treated with concurrent chemoradiation. Echocardiogram showed pedunculated tumor in the right atrium (RA), and computed tomography demonstrated multiple pulmonary tumor embolism. Surgical specimen from the RA showed squamous cell carcinoma resembling the primary cervical tumor, and the peduncle appeared to originate from within the IVC. Postoperative ultrasonography showed severe stenosis of the abdominal IVC due to the invasive growth of para-aortic lymph node metastases. The stalk of the tumor originated from this lesion. We present an extremely unusual case of intraatrial metastatic tumor originating from the para-aortic lymph nodes of cervical cancer.
