RESUMO
Coronary vasospasm plays an important role in the pathogenesis not only of variant angina, but also of ischemic heart disease in general, including other forms of angina pectoris, acute myocardial infarction, and sudden death. Vasoactive events leading to an acute reduction in regional myocardial flow in the presence of a normal or previously compromised circulation are a common cause of arrhythmias. However, coronary vasospasm-induced electrical and mechanical complications are rarely reported in patients with angiographically normal or near-normal coronary arteries. This paper presents our experience with a patient presenting with coronary vasospasm-associated ventricular fibrillation without findings of significant coronary artery disease.

Bronchial mucoepidermoid carcinoma is uncommon, representing 0.2% of all lung tumors. The disease usually presents with symptoms of airway obstruction and recurrent pneumonia. It is commonly classified into two grades in Korea, low and high. We report a case of a bronchial mucoepidermoid carcinoma in a 40-year-old woman who complained of symptoms of an upper respiratory infection. The histological grade after a bronchoscopic biopsy was intermediate. A left upper lobectomy was performed as treatment. The TNM stage of this case was IA (T1N0M0). In addition, 25 cases of bronchial mucoepidermoid carcinoma from 1984 in Korea are also reviewed from the viewpoint of the relationship between the histological grade, TNM stage and clinical course of the tumor.
