Lymphoreticular tumors of the orbit.
Lymphoreticular tumors in the orbit are uncommon. Only 42 patients were identified from over 2000 patients with tumors of lymphoid tissue seen between 1958 and 1979. The patients were divided into 3 groups: primary malignant, secondary malignant, and benign lymphoma. In the primary malignant lymphoma groups, there were 24 patients with a median age of 64 (40 to 87) years and a 2.4:1 female to male ratio: 2 cases were bilateral. In 19 (79%) patients with the lymphoma limited to one orbit the tumor was controlled in every case with doses from 25 to 45 Gy. There were no serious complications. Subsequently lymphoma developed at other sites in 7 (37%) patients. The 5 and 10 year cause specific actuarial survival rates were 70 and 62%. In the 8 patients with secondary malignant lymphoma, the orbital disease was controlled by irradiation, although all patients required further treatment and died of their disease. Radiotherapy controlled all 7 patients with benign lymphoma without any complications.
