Abstract
OBJECTIVE: To investigate the causes of recurrence and malignant change of pleomorphic adenoma (benign mixed tumour) of lacrimal gland. METHODS: 42 cases with the adenoma were followed postoperatively, the follow-up periods ranging from 0.5 to 17.0 years. RESULTS: In the follow-up, 34 cases had no recurrence or malignant change, and 8 cases had recurrences. Of the cases with recurrences, 7 cases had undergone several times of surgeries, because of incomplete resection of the tumor leading to recurrence. CONCLUSION: The key points to obtain success of the surgery and to decrease the rate of recurrence are complete removal of the tumor in its capsule in the initial surgery, and avoidance of aspiration or biopsy made before the operation.
