The 5 leading malignant orbital tumors were adenocarcinoma (207 cases), squamous cell carcinoma (135 cases), rhabdomyosarcoma (52 cases), lymphosarcoma (39 cases), and malignant mixed tumor (29 cases). The 5 leading benign orbital tumors were cavernous hemangioma (304 cases), benign mixed tumor (109 cases), inflammatory pseudo-tumor of the orbit (101 cases), dermoid cyst (100 cases), and optic meningioma (65 cases). Rare tumors of the orbit included 1 case each of alveolar soft tissue sarcoma, chondrosarcoma, mesenchymal chondrosarcoma, synovial sarcoma, giant cell tumor, granular myoblastoma, metastatic leiomyosarcoma of the uterus and metastatic lymphoepithelioma.
