Comparison of the clinical characteristics of benign and malignant eyelid lesions: an analysis of 1423 eyelid lesions, compared between ophthalmology department and plastics department.

Abstract

Oculoplastic surgeons excise and reconstruct eyelid tumors, although plastic surgeons have traditionally managed these cases. Current demand of this surgery is growing, and planning referral services is a health management necessity. This pilot study retrospectively reviewed same population eyelid specimens excised by both disciplines comparing data. Clinical and epidemiologic features of 1423 eyelid lesions biopsied between 2015- 2020 in Emek Medical Center (EMC), Israel were reviewed. Among 1423 specimens, 1210 (85.0%) were benign and 213 (15.0%) were malignant/pre-malignant. Mean age at diagnosis was significantly higher in malignant tumors than in benign tumors (76 and 59years respectively, p value < 0.001). The most common benign eyelid lesions were soft fibroma (20.1%), seborrheic keratosis (11.0%) and melanocytic nevus (10.3%). The most common malignant/pre-malignant eyelid tumors were basal cell carcinoma (BCC) (9.2%), actinic keratosis (2.6%) and Bowen's disease (1.9%). Ophthalmology removed 37 malignant/pre-malignant lesions (5.4%) out of 683 compared to plastics removing 142 malignant/pre-malignant lesions out of 740 (19.2%) specimens. Eyelid malignancy in the plastics department was significantly higher than in the ophthalmology department (p value < 0.001). 270 (70.0%) lesions caused by UV exposure were removed by plastics and 116 (30.0%) were removed by ophthalmology (p value < 0.001). Eyelid lesions in patients aged 76 or older are more likely to be malignant. Ophthalmology eyelid specimens in younger patients are more commonly benign and related to inflammation. Specimens from the plastics department are more commonly malignant, related to UV-exposure, and are from older patients. This difference may be due to a misconception that plastic surgeons have more eyelid cancer reconstruction experience than oculoplastic surgeons, or less awareness of the oculoplastic expertise available today.
