Résumé
We report an extremely rare case of renal cell carcinoma (RCC) extending into the left atrium through the pulmonary vein next to lung metastasis. The patient was a 76-year-old man. Extirpation of the RCC in the right kidney was carried out. Metastasis to the lungs, mediastinal lymph nodes and the pubis were diagnosed and 4 years later, a myxoma-like tumor was formed in the left atrium by echocardiography. We extirpated of the tumor. During surgery, continuity with the metastatic lesion in the right lung, right inferior pulmonary vein and the left atrium was suggested. Histopathologic examination showed the same histopathology as seen in the RCC.
Résumé
The prognosis of rhabdomyosarcoma is poor, and its estimated survival is less than year even after radical resection. We report a patient with recurrent rhabdomyosarcoma 11 years after obtaining remission by radical surgical resection and chemotherapy.
Résumé
Primary cardiac tumors are extremely rare and can originate within the heart or be the result of tumor spread from other sites. We report a female patient with a pulmonary vein tumor extending into the left atrium that had a suspicious primary malignant origin with a sacral metastatic carcinoma. The patient was admitted complaining of pain in her buttock area as a result of a sacral tumor. It was believed that the sacral tumor was a metastasis from the imaging study and clinical manifestation. The primary malignant origin was evaluated. The chest CT showed a left atrium thrombus-like lesion without a pulmonary abnormality. After a transesophageal echocardiogram, the patient was diagnosed with a pulmonary vein tumor extending to the left atrium. The patient was given palliative radiotherapy for the sacral pain. Initially, the clinical impression was a metastatic sacral tumor with a thromboembolism of the left atrium. However, this patient was finally diagnosed with a pulmonary vein tumor with a left atrium extension by a transesophageal echocardiogram.
