Abstract
THERE ARE few population-based studies on malignant tumors of the skin other than those for melanoma, basal cell, and squamous cell carcinoma.1,2 Even less epidemiologic information exists for malignant tumors from defined anatomic regions such as the eyelids. Knowledge about uncommon malignant tumors of the eyelid is based principally on case series from tertiary care facilities, where referral bias may affect results and incidence rates cannot be determined because denominator populations are unknown.3-7 We used the Florida Cancer Data System (FCDS) registry to study the types and distribution of malignant tumors of the eyelid other than basal cell and squamous cell carcinoma.
