The aim of this study was to determine the clinicopathologic characteristics and evaluate the prognostic factors in eyelid malignancies. This was a retrospective, comparative, case series of 70 patients with eyelid malignancies. The mean age at diagnosis was 72.0 years (range 30.5–93.0 years) with 64.3% female. The 2 most common histologic types were basal cell carcinoma (BCC) followed by sebaceous gland carcinoma (SGC). In total, 47.1% of the malignancies were located in the lower eyelid and the majority of tumor (T) category was T1. The authors assessed the disease-specific survival rates of 64 surgical patients using Kaplan Meier curves. Univariate and multivariate analyses identified the predictors associated with disease-specific survival. Of the 64 surgical patients, 4 had regional nodal metastasis (2 SGC, 1 squamous cell carcinoma [SCC], and 1 adenocarcinoma) and distant metastasis at diagnosis was in 3 patients (2 SGC and 1 malignant melanoma [MM]). Six patients died of disease during follow-up. The 5-year disease-specific survival in BCC, SCC, and SGC were 100%, 100%, and 64.8%, respectively. The predictive factors affecting worse disease-specific survival on multivariate models were T4 category (adjusted hazard ratio [aHR] 14.15, P = 0.022) and tumor recurrence (aHR 6.84, P = 0.045). In conclusion, BCC was the most common eyelid malignancy in southern Thailand followed by SGC. In this study, T4 category and tumor recurrence were the most important prognostic factors in eyelid malignancies.
