Pathological Outcomes of Eyelid Tumors Running title: Eyelid Tumors

Abstract

Objectives: To evaluate and compare the pathological outcomes, demographic and clinical features of benign and malignant tumors of the eyelid. Methods: The records of patients who were operated on for eyelid tumors in the oculoplastic surgery unit of our clinic were retrospectively reviewed. The age and sex of the patient, the location and laterality of the tumor, the histopathological diagnosis of the lesion, and whether it was benign or malignant were recorded. Results: A total of 251 patients who were operated on for eyelid tumors and underwent histopathological examination were included in the study. Histopathological results showed benign eyelid tumors in 230 patients (91.6%) and malignant eyelid tumors in 21 patients (8.4%). The age of the patients in the malignant eyelid tumors group was significantly higher than in the benign eyelid tumors group (p<0.001). The localization rate on the right side was significantly higher in malignant eyelid tumors compared to benign eyelid tumors (p=0.003). The lower eyelid localization rate was significantly higher in malignant eyelid tumors than benign eyelid tumors (p<0.001). Conclusion: Although the majority of eyelid tumors are benign, the pathological results of the patients are extremely important so that malignant masses that appear benign are not overlooked. It should be kept in mind that these tumors have a high probability of malignancy, especially in advanced age and lower eyelid locations, and may lead to serious morbidity if treated late.
