RESUMO
Acute promyelocytic leukemia is a special type of acute myeloid leukemia. Patients with this disease are at high risk of complications. Right atrial thrombosis is a rare but potentially serious complication. A 55-month-old girl with acute promyelocytic leukemia M3 was in her last phase of treatment. Radiologic examination revealed an echo structure in the right atrium that was still present after 6 weeks of anticoagulation treatment with enoxaparin. Cardiac surgery was performed to remove the mass, which was found to be a calcified thrombus. Although this is a rare occurrence, recognition of the possibility of a calcified thrombus may minimize misdiagnosis and allow surgical retrieval if the thrombus is sufficiently large.
RESUMO
Primary pericardial mesothelioma is an extremely rare cancer with a short survival prognosis. Clinical symptoms are often atypical, and most patients are diagnosed after surgery or at autopsy. We report a case of a 35-year-old female patient with multiple serous membrane effusion for more than 1 year. The patient underwent pericardial, pleural, and peritoneal fluid drainage many times and underwent many laboratory tests to find the cause; however, there was no definitive diagnosis. She was admitted to the hospital because of shortness of breath, cough, and sputum for 5 days. She underwent extensive pericardiectomy to resolve the dyspnea and pericardial surgery to find the cause of the multiple serous membrane effusion. After surgery, her dyspnea was relieved, and the serous effusion gradually decreased.
