Abstract
Summary A retrospective review of 376 pediatric orbital tumor cases seen at the Ankara University Eye Clinic between 1963 and 1993 was undertaken. The diagnosis was made histologically in every case. Secondary tumors accounted for 127 cases (33.8%), cystic lesions for 82 cases (21.8%), rhabdomyosarcomas for 66 cases (17.6%), neurogenic tumors for 23 cases (6.1%), vascular lesions for 21 cases (5.6%), inflammatory lesions for 21 cases (5.6%), lymphoma and leukemias for 18 cases (4.8%), other mesenchymal tumors for 11 cases (2.9%), metastatic tumors for 5 cases (1.3%), traumatic foreign bodies for 2 cases (0.5%), and lacrimal fossa lesions for 1 case (0.3%). The most common benign orbital tumors were the cystic lesions. The most common primary malignant tumor was rhabdomyosarcoma. Overall, the most frequent orbital lesion was the secondary orbital invasion of retinoblastoma.
