A Case of Pheochromocytoma Presented with Cardiogenic Shock and Followed by Spontaneous Remission

Pheochromocytoma is derived from the chromaffin cells and patients with pheochromocytoma present with several signs and symptoms by producing, storing and secreting catecholamine. Spontaneous rupture or necrosis of pheochromocytoma is extremely rare, but it can be lethal because of the dramatic change in the circulation such as an acute abdominal emergency or shock. Spontaneous remission of the clinical symptoms due to necrosis of the pheochromocytoma is rare. We describe such a case that presented with cardiogenic shock due to extensive necrosis of the pheochromocytoma and this was followed by spontaneous remission of the clinical symptoms without removal of the pheochromocytoma.

A Case of Intermediate Grade Bronchial Mucoepidermoid Carcinoma and Review in Korean Cases / 결핵및호흡기질환

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.
