Abstract

The authors reviewed 95 cases (46 men and 49 women) of the orbital tumors diagnosed histopathologically at the Department of Ophtalmology, Yeungnam University Hospital from March 1984 through August 1994. Seventy-five cases of benign tumors were found evenly in all decades, but twenty cases of malignant tumors were noticed more frequently in 1st, 6th, and 7th decades. The frequency of benign orbital tumors was in this order; dermolipoma (21%, 20 cases), dermoid cyst (11.6%, 11 cases), mucocele (8.4%, 8 cases), lipoma (7.4%, 7 cases) and pleomorphic adenoma (5.3%, 5 cases). Of malignant orbital tumors, the frequency was in this order; retinoblastoma (3 cases), malignant melanoma (2 cases), sebaceous carcinoma (2 cases), and maxillary sinus carcinoma (2 cases). Malignant orbital tumors of 8 expired patients were revealed as secondary or metastatic tumors.
