Basal cell carcinoma is rare in children and usually is associated with genetic or immune predisposing factors. A 14-year-old otherwise healthy boy who had an eyelid basal cell carcinoma is presented. The tumor was in the subcilliary area in the lateral part of the lower eyelid, was ulceronodular with some pigmentation, and had grown over the past 6 months. The patient's medical history was unremarkable. Systemic and immunologic studies did not find any abnormality that could present a predisposition to skin cancer. The tumor was excised and the resulting eyelid defect was repaired with a semicircular flap. During a follow-up period of 44 months, the patient did not develop any recurrence, de novo tumor, or extraocular disease of any significance.
