The 51 cases of eye tumors were evaluated histologically from May 1980 to August 1987 at Department of Ophthalmology, Catholic University Medical College, Kangnam St. Mary's Hospital. The results were as follows: 1. The ratio of male to female among 51 cases was 1:1.04 and histologically benign tumors 25 cases(49%), malignant tumor 26 cases(51%) respectively. 2. Histopathologic type of the most common benign tumor is dermoid cyst(9 cases, 36%), the next nevi(4 cases, 16%) and the third mixed tumor(3 cases, 12%). Among malignant tumor, retinoblastoma(17 cases, 65.5%) was most common and malignant melanoma(5 cases, 19.3%) follows next. 3. In case of benign tumor, there was almost no occurring differences in each age group but in malignant tumor, it showed the high incidence prior to 9 years of age and after 40 years of age. 4. The locations of tumor in benign tumor were conjunctiva, eyelid, lacrimal apparatus in erder. The most common location in malignant tumor was retina. 5. Looking at histopathologic findings of retinoblastoma, there were endophytic types(13 cases, 76.5%) and exophytic types(4 cases, 23.5%). There were 10 cases(52.5%) of optic nerve invasion and 3 cases among total 4 cases of exophytic types. And also, only one case of optic nerve invasion occurred in cases of rosette formation. |
