Papillary eccrine adenoma is a rare sweat gland tumor with a characteristic histopathological appearance and has a benign clinical course. Five cases were reported in Korea since a report by Song et al. in 1988. We report a case of papillary eccrine adenoma in a 38-year-old male who had a firm, dark brown nodule on the medial surface of the left thigh. Microscopically, the tumor was composed of multiple dilated ducts lined by two or more layers of epithelial cells and the luminal cells showed papillary projections into the lumen in some tubules. Immunoperoxidase staining was positive for CEA, S-100, and EMA. We excised the lesion completely and no evidence of recurrence was observed for 6 months.

To examine prospectively the efficacy and reliability of excimer laser photorefractive keratectomy for myopia. we treated 147 eyes of 86 patients with a VisX Twenty/Twenty excimer laser and followed them up for 1 year and follow up 48 eyes of 26 patients for 2 years. The patients were divided into two groups with preoperative myopia: group 1 with diopters between -1.50 and -6.00, group 2 with diopters between -6.01 and -10.00. At 1 year, the group 1 with a mean preoperative refractive error of -4.61D changed to -0.40D, the group 2 changed from -7.50D to -0.92D. At 2 years, the group 1 with a mean preoperative refractive error of -4.28D changed to -0.41D, the group 2 changed from -7.75D to -1.04D. At 1 yera, in group 1, 90.91% (70 of 77) of eyes and in group 2, 64.29%(45 of 70) of eyes were corrected within 1D of intended refraction,respectively. At 1 years, in group 1, 94.81% (73 of 77) of eyes and in group 2, 84.29%(59 of 70) of eyes achieved an uncorrected visual acuity of 0.5 or better. And at 2 years, in group 1, 81.82% (18 of 22)of eyes, and in group 2, 50.00% (13 of 26) of eyes were corrected within 1D of intended refraction, respectively. At 2 years, in group 1, 95.50% (21% of 22) of eyes and in group 2, 84.62%(22 of 26) of eyes achieved an uncorrected visual acuity of 0.5 or better.

The authors experienced a case of embryonal rhabdomyosarcoma. The patient was 13 years old bov who had exophthalmos, ocular deviation to upper direction and visual disturbance of his left eye. We excised the exposed mass of tumor by exploration of the orbit and postoperative irradiation with Cobalt-60 was followed. There were no signs of recurrence of the tumor or metastasis to the other part of body until now, 7 months after surgery. We had a study of the histopathologic findings for a case of rhabdomyosarcoma with a brief review of relating literature.

In man the epiglottis is a thin lamella of yellow elastic cartilage. The upper part is free and is known asleaf and lower part participates in the formation of the anterior wall of the vestibule of the larynx. Theipithelial covering extends forwards onto the base of the tongue over the medial glossoepiglottic folds. The sidesof epiglottis are connected with the cartilages of Wrisberg and arytenoid cartilage by the aryepiglottic fold. Inview of these anatomical complexities, the function and physiology of the epiglottis have been debated sinceMagendi(1815), who proposed the theory that the epiglottis acts as a flap valve to prevent food entering thewindpipe, and who found that he could remove the free part of the epiglottis in dog without spoiling the dog.Follwoing the introduction of laryngoscopy(Garcia, 1815; Liston, 1840; Czermark, 1861) and modern cineradiographicequipments in 1950's, the anatomy and physiology of epiglottis has become much clearrer. Age as it is seen on thelateral x-ray of the neck. In the present study we have made an attempt to systematically analyze aging changes ofthe epiglottis in the lateral x-ray of the neck in 245 healthy adults. The age ranged from 16 to 65 years old.Based on our observation the epiglottis was classified into type A, B, and C according to their curvatures. Thus,type A represented those with posterior curvature, type B those with straight epiglottis and type C anteriorcurvature. Type C was sudivided into I, II and III according to the degree of curvature. Thus, type C-I, C-II andC-III represented mild, moderated and marked anterior curvature, respectively. Type A epiglottis was found in thesecond, third and fourth decades and type C-III in the older age group. Type A was least comon and type C mostprevalent. It seems that the epiglottis inclines anteriorly with backward curvature with age (p<0.0001).

The authors experienced a case of falciform retinal fold which occurred congenitally in the right eye of a 13 years old Korean female. This was situated in the inferior nasal quadrant in the extreme periphery of the retina and was associated with abnormal shape and position of disc and macula without foveal reflex. Visual acuity of right eye was 20/50 and refractive error was not present. We described the characteristic fundus findings of this case with brief review of relating literature.
