In human, Human Papilloma Virus(HPV) is associated with benign squamous tumors in a variety of body sites. But the relationship between HPV infection and malignant epithelial lesions is not clear. Esophageal squamous papilloma is relatively rare tumor but it is reported with increasing frequency recently. We reviewed twenty six patients of esophageal papilloma diagnosed by endoscopic biopsy from 1990 to 1994. The results are as follows; The peak age is fifth decade, men and women ratio is 1: 1.2. Most papillomas located in distal esophagus and have no specific symptoms related to papilloma. All case are sessile form and no malignant change in follow up endoscopy.

Objectives: The effect of coronary artery diameterson theoccurrence of atherosclerosis is unknown. However, several studies have shown that the larger the vessel lumen diameter after coronary interventions, the less the probability of restenosis. We supposed that larger coronary arteries have a lower prevalence of atherosclerosis. Methods and Materials: We measured the diameters of major coronary arteries in 231 patients undertaken coronary arteriography who admitted to Paik hospital from August 1996 to May 1997. Results: The mean diameters of the left main coronary, the right coronary, the left anterior descending and the left circumflex arterieswere 4.50±0.372, 3.62±0.391. 3.55±0.404, and 3.17±0.392mm respectively. On the basis of these dimen-sion of each artery, all patients were divided into 3 groups according to the diameter: gloup A (average), group S(small), group L(large). Group A means that the diameter is within 1 SD of the mean. Group S and group L mean that the diameters are>1 SD smaller and larger, respecti-vely, than the mean. We compared the frequency of lesions ≥50% dia- meter stenosis in groups S and L for each artery. In group S versus L, respectively, the frequency of ≥50% lesion was 6.7% versus 2.6% (P = 0.40 7) in the left main artery, 60% versus 33.3%(P = 0.030) in the right coronary artery, 57.1% versus 35% (P = 0.044) in the left anterior descending artery, and 47.2% versus 23.7% (P = 0.034) in the left circu- mflex artery. For the left main artery, there was a trend toward higher frequency of lesions ≥50% stenosis in group S versus group L. For the other major vessels, the fr-equency of lesions ≥50% in the proximal or midsegment was significantly higher in gr- oup S than in group L. Conclusion: We observed that smaller coronary arteries had a higher prevalence of co- ronary disease in this study. Thus, small coronary artery dia- meter may be a risk factor for atherosclerosis.
