title: Sebaceous carcinoma of the eyelid - different diagnostic times, different outcomes: case reports.
abstract: Sebaceous carcinoma of the eyelid is a very rare slow-growing tumor and is considered an aggressive eyelid neoplasm. It can reach mortality rate of about 6%. Diagnosis is often delayed because of its ability to masquerade as other periocular lesions, both clinically and histologically. We present three cases of sebaceous carcinoma, with different surgical outcomes, showing the importance of early diagnosis.
