Pericardial effusion-induced subcutaneous edema in the trunk and lower limbs after percutaneous drainage for carcinomatous pericarditis: report of a case.

The recurrence of gastric cancer is rarely associated with cardiac tamponade induced by carcinomatous pericarditis. We encountered a patient in whom cancer recurred as carcinomatous pericarditis 9 years after surgery for advanced gastric cancer. Furthermore, pericardial effusion caused marked subcutaneous edema in her trunk and lower limbs after percutaneous pericardial drainage was applied to treat cardiac tamponade. A 49-year-old woman presented with lower limb edema and exertional dyspnea 9 years after distal gastrectomy for advanced gastric cancer. Chest computed tomography and ultrasonography showed bilateral pleural effusion and pericardial effusion. Pericardial drainage and thoracocentesis were performed, and her symptoms of respiratory distress remitted. Class V adenocarcinoma was detected on cytology from both effusions, and was diagnosed as the recurrence of gastric cancer. After systemic chemotherapy, she was admitted for the aggravation of dyspnea because of recurrent retention of pericardial effusion. Pericardiocentesis was repeated. The pericardial effusion became subcutaneously retained in the trunk below the puncture site over the lower limbs via the drainage route. Edema in the trunk below the abdomen and lower limbs gradually aggravated over time. The skin extended and became sclerotic because of severe edema, liquid leaked from abdominal skin injuries, and the condition became similar to skin lymphorrhea in lymphedema. Neoplastic cardiac tamponade due to gastric cancer has an extremely low incidence and a poor prognosis. We encountered a patient in whom pericardial effusion caused subcutaneous edema in the trunk and lower limbs after percutaneous pericardial drainage was applied to treat carcinomatous pericarditis associated with gastric cancer.
