Analysis of Classification and Incidence of Eyelid and Orbital Tumors

ABSTRACT

We histopathologically analysed 221 consecutive cases of lid(97 cases ) and orbital(124 cases) tumors from 1992 through 1996 to investigate types and incidence of tumors. In cases of eyelid tumor, cystic tumors accounted for 32 cases (33.0%), basal cell carcinomas 15 cases, nevus 11 cases, sebaceous gland carcinomas 10 cases, cavernous hemangiomas 9 cases, squamous cell carcinomas 8 cases, papilloma 6 cases, pseudotumors 3 cases and lipoma 3 cases. The most common tumors were basal cell carcinoma(24.6%) in adults and cystic tumors(64.4%) in children. In cases of orbital tumor, cystic tumors were the most frequent type of lesions, responsible for 22 of the 124 cases, followed by secondary tumor 16 cases, lacrymal lesions 15 cases, pseudotumors 15 cases, lymphomas 15 cases, hemangioma 11 cases, lipoma 10 cases, peripheral nerve tumors 6 cases, optic nerve gliomas and meningiomas 5 cases, fibromas 5 cases and rhabdomyosarcomas 4 cases. The most common tumors were lacrimal tumors(17.3%) in adults and cystic tumors(50.0%) in children.
