This paper analysed the pathologic classification of 435 primary orbital tumors, which were mainly divided into eight types, including 83 cases (19.1%) of cystic lesions, 64 cases (14.7%) of vasculogenic lesions, 50 cases (11.5%) of mesenchymal tumors, 73 cases (16.8%) of lacrimal gland epithelial lesions, 54 cases (12.4%) of neural tissue tumors, 55 cases (12.6%) of lymphocytic lesions, 16 cases (3.7%) of histiocytic lesions and 40 cases (9.2%) of idiopathic orbital pseudotumor. The clinicopathologic characteristics of the common orbital tumors were also discussed.
