Eccrine poroma is a benign neoplasm, whicn is thought to originate from the eccrine sweat gland. Previous studies suggest that these are primarily lesions of the hairless acral surface. We report a clinicopathological case of a 30-year-old man who presented with a 2.0 by 1.2 cm sized, unusual scalp lesion, which proved to be an eccrine poroma. There has been no local recurrence in the 4 months since complete excision.

To investigate the receptors mediating the regulation of norepinephrine (NE) release in human cerebral cortex slices, we examined the effects of opioid agonists for mu-, delta-, and kappa -receptors on the high potassium (15 mM) -evoked release of [3H]NE. [3H]NE release induced by high potassium was calcium-dependent and tetrodotoxin-sensitive. [D-Pen2, D-Pen5]enkephalin (DPDPE) and deltorphin II (Delt II) inhibited the stimulated release of norepinephrine in a dose-dependent manner. However, Tyr-D-Ala-Gly- (Me) Phe-Gly-ol and U69, 593 did not influence the NE release. Inhibitory effect of DPDPE and Delt-II was antagonized by naloxone, naltrindole, 7-benzylidenaltrexone and naltriben. These results suggest that both delta 1 and delta 2 receptors are involved in regulation of NE release in human cerebral cortex.

Most patients with hypertension and no definable cause are said to primary or essential hypertension, while other patients with hypertension and specific causes are siad to secondary hypertension. Approximately 5% fo patients with hypertension have specific causes. The patients of secondary hypertension should not be ignored for the reason: The elimination of cause for hypertension can normalize the blood pressure. Juxtaglomerular cell tumor is a rare condition of secondary hypertension, with only approximately 70 cases reported to date. The higher the level of blood pressure, the most likely that various cardiovascular diseases will develop prematurely through acceleration of atherosclerosis. But Acute myocardial infarction in young hypertensives has been reported rarely. We describe the rare case of a young patient with acute myocardial infarction associated with secondary hypertension by renal juxtaglomerular cell tumor.

Zollinger-Ellison syndrome is a very rare disease that's caused by tumor having gastrin-producing cells, and this is accompanied by hypergastrinemia leading to gastric acid hypersecretion, peptic ulcer and their complications. A 60-year-old man presented with epigastric pain and soreness he had experienced for 7 days. The endoscopic findings showed reflux esophagitis and multiple active ulcers at the antrum, the duodenal bulb and the 2nd and 3rd portions of the duodenum. The fasting serum gastrin level was markedly elevated above 1,470 pg/mL and this was consistent with the findings of gastrinoma. We confirmed the presence of gastrinoma via the abdomen CT scan and selective intra-arterial calcium injection. This is the first Korean case report of gastrinoma that was localized by selective intra-arterial calcium injection.

We experienced a rare case of trachea diverticula combined with the sequela of tuberculosis and a fungus ball. The patient had complained of coughing and hemoptysis for a long time after experiencing tuberculosis. He was admitted due to hemoptysis and the aggravation of coughing. The CT scan showed a variable sized trachea diverticula combined with tuberculosis sequela and a fungus ball in the right lung fields. The diagnosis was made by bronchoscopy and a CT scan. After bronchial artery embolization and conservative treatment, the patient's symptoms improved and the patient was discharged.
