Eccrine poroma is a benign skin appendage tumor originating from the intradermal part of the sweat duct. It is found commonly on the hairless surface of the feet, although eccrine poroma of the hands, head, trunk, and legs have been reported. Histopathologically, the tumor extends from the lower portion of the epidermis into the dermis as broad, anastomosing bands. The tumor cells are smaller than squamous cells, having a uniform cuboidal appearance and a round, deeply basophilic nucleus, connected by intercellular bridges. In eccrine poromas, narrow ducta1 lumina and occasional cystic spaces are found within the tumor bands, but a large cystic space is very unusual. We report a case of eccrine poroma with a large cystic space extending from epidermis into the reticular dermis.

Diffuse neonatal hemangiomatosis is rare and a life-threatening disorder characterized by multiple cutaneous and visceral hemangiomas. The organs most commonly affected are the liver, lung. brain, GI tract. The complications are high output cardiac failure, hemorrhage, Kassabach-Meritt syndrome, etc. A 30-day-old girl was diagnosed to have diffuse neonatal hemangiomatosis by her multiple cutaneous and hepatic hemangiomas. She was treated with corticosteroid and interferon alfa-2a. During the treatment the number and size of hemangiomas were markedly reduced.

BACKGROUND: The coronary collateral circulation has been frequently observed in significant coronary artery disease and its protective role in ischemic myocardium is still remained unclear. But the study on the anti-ischemic effect in human model of ischemic myocardium is rare. METHODS: To observe the anti-ischemic role of coronary collateral circulation in ischemic myocardium, perfusion defect areas were measured during PTCA(percutaneous transluminal coronary angioplasty) in angina patients with single vessel disease and analyzed according to the grade of collateral circulation. The 99mTc-MIBI myocardial scanning images were obtained at 24 hours before PTCA with dipyridamole stress, at ballooning during PTCA and at 24 hours after the opening of the artery and perfusion defect volume ratios(DVR) were measured in each of the images of the patient with angina and single vessel disease. RESULTS: 1) Studied subjects were 14 patients(10 male, 4 female, mean age : 56.6+/-103) and subdivided into two groups. All patients had angina with single vessel disease, 7 proximal left anterior descending artery(LAD) stenosis, 4 middle LAD stenosis, 1 middle right coronary artery(RCA) stenosis and 2 proximal left circumflex artery(LCX) stenosis. Group A was composed of 7 patients with angina and coronary collateral circulation more than grade 1. Group B was 7 patients with angina and grade 0 collateral. 2) Mean age of group A was 62.4+/-8.2 years, 5 male and 2 female patients, That of group B was 56.6+/-8.9 years and all male patients. Group A was composed of 7 patients ; 5 unstable and 2 stable angina ; 2 proximal LAD stenosis, 3 midddle LAD stenosis, 1 middle RCA stenosis and 1 proximal LCX stenosis. One patients had grade 1, two patients grade 2 and four patients grade 3 coronary collateral circulation. All of the patients were unstable angina in group B showing 5 proximal LAD stenosis, 1 middle RCA stenosis and 1 proximal LCX stenosis. No collateral circulation was demonstrated in group B. 3) In group A, DVR was 17.5+/-13.9% on stress image before PTCA and 7.1+/-1.4% on the ballooning image during PTCA. DVR was smaller in ballooning image than in stress image(p<0.01). 4) In group B, DVR was 12.4+/-16.0% on stress image before PTCA and 26.6+/-10.0% on ballooning image during PTCA. DVR was larger in ballooning image than in stress image(p<0.001). 5) DVR on stress image and open image were not different in both groups, but DVR on ballooning image were 7.1+/-4.7% in group A and 26.6+/-10.0% in group B, which was larger than in group A(p<0.01). CONCLUSION: These results suggest that myocardial perfusion defect area may be smaller in angina patients with good collateral circulation than patients with no collateral, and coronary collateral circulation have a protective role on the jeopardized myocardium during coronary artery occlusion.

BACKGROUND: Idiopathic left ventricular tachycardia (ILVT), one of common idiopathic ventricular tachycardias which develop without structural abnormality of the heart. It has been reported that ILVT has a typical QRS morphology of right bundle branch block and left axis and unique clinical and electrophysiological characteristics. Intravenous verapamil is shown to be very effective in acute termination. However, radio-frequency catheter ablation is now recommended as the treatment of choice for long-term managemnt. This study was performed to determine the clinical and electrophysiological characteristics of ILVT and to evaluate the effects of radiofrequency catheter ablation (RFCA) of ILVT. METHODS: Seventeen patients (12 men, 5 women:mean age : 39+/-15 years) with ILVT were included in this study. ILVT was diagnosed based on the results of electrocardiogram, echocardiogram, cardiac catheterization, and electrophysiology study (EPS). EPS was performed with the standard technique in fasting state for more than 6 hours. In patients with their clinical VTs reproducibly induced during EPS, RFCA was attempted using endocardial activation mapping and pace-mapping. The mode of induction and termination, response to verapamil, and site of origin of the ILVT were evaluated. The local electrogram chacteristics at the sites of successful catheter ablation were also evaluated in patients undergoing RFCA. RESULTS: All 17 patients presented with recurrent palpitation but none with syncope or sudden cardiac death. None had a significant heart disease. The spontaneous ventricular tachycardias were of right bundle branch block morphology with left superior axis in 11 cases, right inferior axis in 1, and northwest axis in 5. The VTs were terminated with intravenous verapamil in all of 14 patients receiving IV verapamil. VT of same morphology as the clinical VT was induced with programmed electrical stimulation in 13 cases (76.4%), of whom 2 cases required isoproterenol infusion. The most frequent mode of induction was single ventricular extrastimulation (7 cases). Mean cycle length of the induced VTs was 320+/-59 ms. RFCA was attempted in 11 cases and successful in 9 (82%). The successful ablation sites were and central mid septum (3 cases), posterior mid septum (3 cases), posterior apical septum (3 patients) of the left ventricle (3 patients). At the successful ablation sites, the local ventricular activation preceded the onset of QRS complex by 34+/-15 ms (range : 10-58) and the paced QRS complexes during pace-mapping were identical to those of the induced or spontaneous VTs in 11.7+/-0.4 leads (range : 11-12). However, Purkinje potential was recorded only in 2 cases. There were no complications associated with EPS and RFCA. CONCLUSIONS: The present study suggests that ILVT is mild in symptoms, highly sensitive to verapamil, mostly caused by reentry, and can be cured by radiofrequency catheter ablation guided by pace-mapping and activation mapping.

Annular elastolytic giant cell granuloma (AEGCG) is an inflammatory disorder characterized by the annular plaques with serpiginous raised borders on the sun-exposed area. Its pathologic finding shows the patchy granulomatous infiltration composed of multinucleated giant cells, histiocytes, lymphocytes and disappearance of the elastic fibers secondary to being engulfed by the giant cells. We report a case of AEGCG in a 59-year-old-male. He had several annular, erythematous plaques with raised borders on his dorsum of the hand, neck, back and the typical histologic features of AEGCG.

PURPOSE: To compare the clinical outcomes between refractive-type multifocal intraocular lenses (IOL) (Lentis Mplus(R) LS 313, Oculentis GmbH., Berlin, Germany) and diffractive-type multifocal IOL (Acrysof Restor(R); SN6AD1, Alcon Lab., Fort Worth, TX, USA) with same near added. METHODS: We evaluated 30 eyes implanted with Lentis Mplus(R) IOL and 33 eyes implanted with Acrysof Restor(R) IOL after phacoemulsification. The distant, intermediate, and near uncorrected visual acuities of the 2 groups were evaluated at 2 weeks and 1, 3, and 6 months postoperatively. Optical quality obtained using the Optical Quality Analysis System II (OQAS II(R), Visiometrics, Castelldefels, Barcelona, Spain), higher-order aberrations (HOAs), and patient satisfaction questionnaire of the 2 groups were evaluated at 3 months postoperatively. RESULTS: The visual acuity of intermediate 100 cm was statistically better in the Lentis Mplus(R) group (p < 0.05). There were no significant differences between the 2 groups with distant, intermediate 63 cm, and near vision. At the 3-month postoperative follow-up, objective scatter index, modulation transfer function (MTF) cutoff value, and pseudo-accommodation range measured by OQAS II(R) showed no differences between the 2 groups, but Strhel ratio was higher in the Acrysof Restor(R) group. HOAs of 5 mm and 6 mm increased significantly in the Lentis Mplus(R) group. No significant differences were found in the patient satisfaction questionnaire. CONCLUSIONS: Both refractive and diffractive-type multifocal IOL implantation in patients with cataracts and presbyopia offered good and comparable visual acuity at distance and near. However, the Lentis Mplus(R) IOL provided better intermediate vision than the Acrysof Restor(R) IOL.

BACKGROUND/AIMS: Superficial esophageal squamous cell carcinoma (SESCC) is being increasingly detected during screening endoscopy. Endoscopic submucosal dissection (ESD) allows for en bloc and histologically complete resection of lesions. This study assessed the technical feasibility and long-term outcomes of ESD for SESCCs. METHODS: Between January 2005 and August 2012, 27 patients with 28 SESCCs underwent ESD at Pusan National University Hospital. The en bloc and pathologically complete resection rates, complication (perforation and bleeding) rate, incidence of esophageal stricture after ESD, and overall and disease-specific survival rates were evaluated. RESULTS: The en bloc and pathologically complete resection rates were 93% and 83%, respectively. No significant bleeding occurred, and perforation with mediastinal emphysema was observed in two patients (7%). Post-ESD stricture occurred in two patients (7%) who had mucosal defects involving more than three-fourths of the esophageal circumference. During a mean follow-up of 23 months, local tumor recurrence was seen in two of four lesions with pathologically incomplete resection; one was treated by re-ESD, and the other was treated by surgical esophagectomy. The 5-year overall and disease-specific survival rates were 84% and 100%, respectively. CONCLUSIONS: ESD seems to be a feasible, effective curative treatment for SESCCs. All patients should be closely followed after ESD.
