RESUMO
A 38-year-old man presented with typical squeezing-type anterior chest pain. An initial electrocardiogram (ECG) showed prominent ST-segment elevation (V1-V4 lead, 3 mm). Suddenly, the patient fell unconscious and had no pulse. At that time, the ECG showed polymorphic ventricular fibrillation (VT). After direct current (DC) cardioversion, the patient regained vital signs and defibrillation converted the VT into an accelerated idioventricular rhythm with resolution of the ST-segment elevation. The patient was referred to our hospital for close observation and further evaluation. At our hospital, an ECG showed normal sinus rhythms and cardiac enzymes were within normal limits. We diagnosed the patient with variant angina rather than ST elevation myocardial infarction (STEMI), because his clinical manifestations were quite distinct; ST-segment elevations disappeared slowly at the reperfusion stage. However, the patient's final diagnosis was STEMI because coronary angiography showed severe eccentric tubular stenosis (85%) with remnant thrombus in the middle left anterior descending artery. Defibrillation likely removed the thrombus, which led to STEMI.

Imatinib mesylate, a selective inhibitor of BCR-ABL kinase activity, has demonstrated significant clinical efficacy in the treatment of chronic myeloid leukemia (CML) and gastrointestinal stromal tumors (GISTs). It has become the standard of treatment for these diseases. Although the toxicity profile of imatinib is superior to that of interferon or other cytotoxic agents, some adverse events including edema, gastrointestinal toxicities and hematologic toxicities are commonly observed in the patients treated by imatinib. We present two cases of imatinib induced interstitial pneumonitis during the treatment of a chronic phase of CML.

Thromboembolism is one of the common complications in nephrotic syndrome. The incidence of renal vein thrombosis in the setting of nephrotic syndrome varies from 5% to 62%. Membranous glomerulonephritis (MGN) has been rarely manifested as inferior vena cava (IVC) and/or renal vein thrombosis. We report a case of acute IVC and left renal vein thrombosis as initial manifestation of MGN. The renal vein thrombosis was successfully treated with systemic thrombolysis with temporary IVC filter insertion. After 4 months, MGN was diagnosed by renal biopsy.

Primary cardiac lymphomas (PCL) are extremely rare. Clinical manifestations may be variable and are attributed to location. Here, we report on a case of PCL presenting with atrioventricular (AV) block. A 55 year-old male had experienced chest discomfort with unexplained dyspnea and night sweating. His initial electrocardiogram (ECG) revealed a first degree AV block. Along with worsening chest discomfort and dyspnea, his ECG changed to show second degree AV block (Mobitz type I). Computed tomography (CT) scan showed a cardiac mass (about 7 cm) and biopsy was performed. Pathologic finding confirmed diffuse large B-cell lymphoma. The patient was treated with multi-drug combination chemotherapy (R-CHOP: Rituximab, cyclophoshamide, anthracycline, vincristine, and prednisone). After treatment, ECG changed to show normal sinus rhythm with complete remission on follow-up CT scan.
