Abstract
Purpose :
To examine the clinical features of eyelid tumors in a tertiary hospital over a 13-year period.
Methods :
Eyelid tumors referred to our hospital, Jichi Medical University, Japan, between 2004 and 2016 were evaluated retrospectively. The incidence of benign or malignant lesions, the pathological classification, age, sex, and tumor location were investigated. Cysts and inflammatory lesions were taxonomically classified into benign tumors. Chalazia and pediatric dermoid cysts were excluded in this study.
Results :
A total of 234 cases were identified. The mean age at diagnosis was 66 +/-18 years. One hundred sixty-one（68.8％）of the tumors were found to be benign cases. The common benign eyelid tumors were 47 (29.1%) nevocellular nevi, 39 (24.2%) seborrheic keratosis, 14 (8.7%) epidermoid cysts, and 14 (8.7%) verruca vulgaris. Seventy-three (31.2％) eyelid tumors were malignant. These included 34 (46.6%) sebaceous gland carcinomas (SGC), 26 (35.6%) basal cell carcinomas (BCC), and 4 (5.5%) squamous cell carcinomas. Whereas BCC affected the lower eyelid more frequently, SGC affected more the upper eyelid than the lower eyelid. Female predominance was seen in both SGC and BCC.
Conclusions :
SGC was the most common malignant tumor in this study which differs from the previous reports in any other countries.
