ABSTRACT
<p>It is reported that myasthenia gravis (MG) with thymoma occupy 20% of all MG and extended thymectomy is recommended. After having operation, it is rare, but cases of recurrence of thymoma and, what is worse, thymic cancer from residual thymus tissue are reported. A 69-year-old man came to our hospital to have his dyspnea level examined. He had a past history of MG with thymoma and he had undergone extended thymectomy 17 years previously. Enhanced CT showed pericardial thickening and many tumors in the epicardium. Catheterization study showed dip and plateau pattern of left ventricular pressure. We therefore diagnosed constrictive pericarditis (CP). We performed pericardiectomy under cardiopulmonary bypass. He was discharged ambulatorily on postoperative day 24. Histological findings of the tumor and the pericardium showed that they were dissemination of thymic cancer. It was considered that thymic cancer caused CP and it was an extremely rare case. We think this is the first report to the best of our knowledge.</p>
ABSTRACT
This report documents the case of a male in his sixties who developed multiple lymph node metastases after receiving external beam radiation therapy and androgen deprivation therapy for locally advanced prostate cancer. Agglomerated pelvic lymph node metastases caused lower extremity lymphedema, however the patient was administered systemic chemotherapy with docetaxel. Because surrounding normal tissue was already irradiated by the prior therapy, radiation against pelvic lymph nodes by LINAC was in danger of exceeding tolerance dose. Therefore, the patient received stereotactic radiosurgery by cyberknife that has a high degree of accuracy in target identification and localization for pelvic lymph node metastases. The lower extremity lymphedema was declined and his activity of daily living was recovered without obvious side effects. Here we report the case of successfully controlled lymphedema by palliative cyberknife therapy.
